Passages from the Life of a Philosopher
Table of Contents
Introduction
A mind forged in numbers confronts a world governed by habit. Charles Babbage’s Passages from the Life of a Philosopher opens not as a quiet recollection but as a sustained encounter between invention and inertia. This autobiography, shaped by decades of effort to design machines that could calculate with unerring exactness, frames an era’s ambitions and anxieties. It navigates the workshop and the committee room, the laboratory and the street, tracing how ideas move from drawing board to public scrutiny. The book offers the record of a life at once technical and civic, attentive to precision yet alert to the human temperaments that enable or obstruct progress.
Its classic status derives from more than historical curiosity; it endures as a defining work in the literature of scientific self-portraiture. Babbage’s prose marries the discipline of engineering with the cadence of Victorian nonfiction, producing a narrative that is both candid and argumentative. The book’s continuing influence rests on its portrayal of the inventor as citizen, designer, and critic. It helped set a pattern for later reflections by technologists who write not only to document achievement but also to interrogate the conditions that make achievement possible. Read as literature, it refines the memoir into a case study of ideas demanding institutions worthy of them.
Passages from the Life of a Philosopher was written by Charles Babbage and published in 1864, in the high Victorian period, after decades devoted to his calculating engines. The volume offers a sequence of episodes from Babbage’s career and public life, combining recollection, analysis, and commentary. It places the reader near the drafting table and the debating hall while keeping the focus on the principles that guided his work. Without offering a comprehensive chronology, it nonetheless sketches the arc of a life devoted to measurement, certainty, and the rational organization of labor. The result is an autobiography unusually sensitive to both mechanism and society.
Babbage’s purpose is plainly stated by the structure of the book itself: he sets out to explain his designs, clarify the reasoning behind them, and record the circumstances that shaped their development. At the same time, he writes to illuminate how scientific work is funded, evaluated, and understood by the public. He defends the integrity of patient inquiry and argues for a culture in which long projects can thrive. The tone moves confidently between exposition and critique, urging readers to see invention as a public good. In doing so, the narrative presents a philosophy of responsibility grounded in facts, figures, and practical experience.
The chapters advance by juxtaposing precise observation with wry, sometimes severe, reflection. Part of the book’s appeal lies in how it captures intellectual temperament: meticulous, resilient, occasionally exasperated, and always intent on clarity. Babbage invites the reader to look closely at tools and processes, to consider the cost of error, and to appreciate how method transforms ambition into reliable action. The prose is attentive to detail without lapsing into opacity, a balance achieved through measured pacing and carefully chosen examples. Memory here is not ornament but instrument, wielded to test assumptions, expose confusions, and model the discipline that underwrites scientific and mechanical success.
A central theme is the moral economy of calculation. For Babbage, accuracy is not merely a technical virtue; it is a civic obligation because the consequences of numerical error extend outward into commerce, navigation, finance, and policy. The book considers how machines can reduce the burden of routine labor while extending the reach of the mind, thereby recasting the relationship between human judgment and mechanical procedure. It also examines the fragility of large undertakings, showing how promise can be delayed when coordination falters. Across these pages, calculation becomes a lens for viewing integrity, foresight, and the careful stewardship of public and private resources.
As literature, the work exemplifies the Victorian art of mixed forms: part memoir, part essay, part technical prospectus, part civic tract. Its episodes are arranged not to satisfy curiosity about every biographical detail but to develop a sustained argument about how knowledge is made operational. Babbage’s narratorial stance is both participant and analyst, bringing the reader into the texture of practice while keeping attention on principle. Rhetorically, he favors the cumulative force of precise cases over abstract flourish, crafting a voice that feels exacting yet accessible. The mosaic structure, with its deliberate digressions, models the very process of iterative design and critical revision he champions.
The book’s influence radiates across histories of technology and studies of Victorian public life. Scholars and general readers alike have turned to it as a primary testimony of early mechanical computation and as an anatomy of how large-scale projects encounter the realities of funding, oversight, and expectation. It shaped the figure of the inventor in cultural memory, not as isolated genius, but as a negotiator of systems. Its blend of personal narrative with policy-minded critique offered a template for later authors seeking to connect technical work with institutional reform. By coupling insight with accountability, it set an enduring standard for technological self-explanation.
For readers interested in the origins of computing, the book presents Babbage’s own account of conceiving, refining, and advocating calculating engines. It shows how ideas evolve through experiment, setback, redesign, and renewed argument, and how public understanding must be cultivated alongside mechanical feasibility. While the narrative refrains from exhaustive specification, it provides the conceptual scaffolding behind designs intended to automate calculation and minimize error. From this vantage, Passages is invaluable: not a schematic, but a reasoning mind on the page, tracing the path from mathematical requirement to engineered possibility, and from private insight to the search for collective means to realize it.
Equally notable is the work’s portrait of scientific culture. Babbage examines how collaboration forms, how credit is assigned, and how standards are established, all while acknowledging the friction that besets deliberative bodies. His analysis is not detached; it is animated by the conviction that institutions must earn public trust by acting with clarity and consistency. The narrative offers glimpses of laboratory habits and workshop economies, and it honors the craftspeople, calculators, and colleagues whose expertise makes theory tractable. In this, it affirms the dignity of distributed skill, suggesting that precision is a social achievement as much as it is an individual virtue.
Passages remains relevant because the questions it asks are still urgent. How should societies support long-horizon research that resists immediate returns? What forms of oversight help, and which hinder? How can complex technologies be explained without distortion or hype? The book’s responses are grounded rather than doctrinaire, insisting on transparency, careful planning, and honest accounting of risk. Contemporary readers will recognize familiar tensions between innovation and policy, enthusiasm and patience, aspiration and constraint. Babbage’s insistence that technical progress and public responsibility must advance together offers a compass for navigating today’s debates about infrastructure, data, automation, and the ethics of design.
To read Passages from the Life of a Philosopher is to encounter a mind that treats autobiography as an experiment in clarity. It is a classic because it articulates enduring themes: the labor of exactness, the politics of knowledge, and the promise of mechanized aid to human thought. Its pages summon curiosity, skepticism, and resolve, inviting readers to measure claims by evidence and to match ambition with method. For contemporary audiences, the book’s lasting appeal lies in its union of intellect and integrity. It affirms that progress is built not only from brilliant ideas, but also from the steady, public-minded work that gives them form.
Synopsis
Passages from the Life of a Philosopher is Charles Babbage’s autobiographical account of his scientific work, public service, and the circumstances surrounding his calculating engines. He frames the book as a factual record meant to clarify aims, methods, and decisions that shaped his career. Setting his narrative in early nineteenth-century Britain, he outlines the institutional landscape of science, the role of government patronage, and the pressures of public scrutiny. The work interweaves personal episodes with technical explanations, emphasizing the practical obstacles of invention and administration. Babbage states his intention to preserve an accurate history of his projects and to inform future efforts in mechanical calculation and scientific organization.
Babbage begins with his early education and introduction to mathematics, culminating in his studies at Cambridge. He recounts founding the Analytical Society with John Herschel and George Peacock, promoting continental methods and Leibnizian notation. These formative experiences establish his focus on rigor and the systematic improvement of science. Alongside academic pursuits, he describes acquaintances with prominent mathematicians and natural philosophers, illustrating how institutional customs and examination practices shaped inquiry. He also notes early encounters with numerical tables and computational errors, foreshadowing his later determination to mechanize calculation. The groundwork of collaboration, reform, and precision laid at this stage guides the developments that follow.
The narrative then turns to the conception of the Difference Engine, prompted by the prevalence of errors in printed mathematical and navigational tables. Babbage presents the principle of finite differences as the engine’s foundation, enabling the automatic production and printing of accurate tables. He recounts securing government support in 1823 and engaging the engineer Joseph Clement to construct parts. Descriptions of workshops, precision tools, and trial assemblies show the technical ambition of the project. Babbage explains partial successes, including a working section demonstrated in the 1830s, while acknowledging incremental revisions as experience revealed new tolerances, costs, and logistical demands inherent to precision machinery.
Practical and administrative difficulties become central as Babbage details breakdowns in relations with his engineer, disputes over costs, and the challenges of relocating machinery and tools. He narrates dealings with the Treasury, committees, and auditors, documenting approvals, delays, and changes in policy. The project’s scale, together with evolving specifications, led to escalating expenses and strained oversight. Ultimately, despite substantial progress on components, construction was suspended, leaving an unfinished engine. Babbage records these events to illustrate the complexities of public funding for innovation, the necessity of clear contracts and continuity, and the consequences of interruptions in large technological enterprises.
The account advances to his broader conception of automatic calculation: the Analytical Engine. Here Babbage distinguishes a general-purpose machine from the earlier special-purpose design. He outlines key features, such as a store and a mill for data and operations, sequences controlled by punched cards adapted from Jacquard looms, and provisions for conditional branching and iteration. He introduces his system of mechanical notation to design and verify complex assemblies. The narrative mentions explanatory examples, including the computation of series, and references to commentary that expounded the engine’s powers. This section emphasizes programmability, precision, and extensibility as central conclusions about the future of calculation.
Beyond machinery, Babbage surveys his interactions with scientific institutions. He recounts founding and participating in societies, contributions to astronomy and statistics, and engagements with international communities. The text presents candid descriptions of elections, committees, and procedures within learned bodies, alongside proposals for clearer rules and more rigorous management. He returns to themes first raised in his earlier critiques, arguing for merit-based recognition and systematic organization to foster discovery. Encounters with leading figures at home and abroad are included to situate British science within a wider European context, showing how standards, communication, and support networks affected the progress and dissemination of research.
The book also treats several public-policy and industrial questions. Drawing on his experience from factories and workshops, Babbage summarizes principles later presented in his writings on the economy of manufactures, including division of labor, standardization, and cost accounting. He reflects on statistics as a tool for administration and improvement. Proposals and observations appear on topics such as railways, signaling, safety, and lighthouses, as well as postal reform and the management of state services. These passages present practical conclusions about measurement, oversight, and incentives, arguing that clear objectives and reliable data can guide both technical systems and public institutions toward greater efficiency and accuracy.
Babbage includes social observations that connect daily life to scientific work. Most notably, he documents campaigns against street nuisances, particularly street music that he argues disrupted concentration necessary for delicate calculations. He compiles instances, petitions, and legal outcomes to demonstrate the impact of noise on study and industry. The discussion extends to urban order, policing, and the responsibilities of authorities to balance entertainment with productive activity. Presented as a record rather than a polemic, these episodes illustrate the conditions under which research proceeds, and how seemingly minor disturbances can influence the pace and reliability of intellectual and mechanical labor.
In closing passages, Babbage reiterates the aims of his memoir: to record the designs and histories of his engines, to outline lessons about administration and invention, and to encourage future realization of automatic calculation. He emphasizes exactness in method, continuity of support for large projects, and the public value of reliable computation. Acknowledging unfinished work, he summarizes what was demonstrated, what was planned, and what remained to be accomplished. The overarching message is that systematic organization, coupled with perseverance and sound design, can advance science and industry. He leaves a documented pathway for successors to refine and implement these ideas.
Historical Context
Charles Babbage’s Passages from the Life of a Philosopher (1864) chronicles a life spanning late Georgian through mid-Victorian Britain, principally centered in London and Cambridge but extending to Paris and Turin. The book’s events unfold amid the consolidation of the British Empire, the maturation of industrial capitalism, and the professionalization of science. Britain’s factories, workshops, and learned societies formed a dense ecosystem in which mechanical invention and mathematical ambition intertwined. Urban growth, new policing, sanitary reforms, and railways transformed daily routines. Scientific London—Royal Society meetings at Somerset House and Burlington House, the Astronomical Society, and later the British Association—provided the institutional stage on which Babbage’s calculating engines, critiques, and campaigns were performed and judged.
The period saw Britain’s ascent as a global manufacturing and maritime power, with steam power, precision engineering, and new machine tools reshaping economic life. Cambridge served as Babbage’s intellectual launchpad, while Paris, still radiant from Enlightenment science despite post-Napoleonic turbulence, offered continental models of state-backed computation. London’s government offices, workshops in Clerkenwell and the West End, and private drawing rooms doubled as laboratories for technological demonstration and debate. Passages reflects this geography: it moves from academic reforms to Treasury negotiations, from international correspondence to salon-like gatherings where fragments of the Difference Engine were shown. The book thereby captures a city and a century where scientific aspiration collided with administrative habit and social anxiety about machines.
An early continental spark came from revolutionary France’s grand project to compute mathematical tables. Around 1819, Babbage studied Gaspard de Prony’s organization of human “computers” for logarithmic and trigonometric tables, an enterprise begun in the 1790s under the Bureau du Cadastre. Guided by division of labor and inspired by Adam Smith, de Prony’s method used platoons of trained clerks to reduce computation to routine. This historical precedent, observed in Paris and reported by savants like François Arago, convinced Babbage that mechanical computation was possible and desirable. In Passages, he links this French administrative ambition to his own vision: replacing regiments of human computers with precise, tireless engines.
The Cambridge Analytical Society, founded in 1812 by Babbage with John Herschel and George Peacock, spearheaded a reform of British mathematical practice. They promoted Leibnizian differential notation over Newtonian fluxions, translating Lacroix and advocating continental rigor. By the 1820s, the movement reshaped the Cambridge Tripos and seeded a new generation of mathematically literate engineers and astronomers. Passages recalls this milieu to show how institutional reform in education enabled more ambitious scientific projects. Babbage’s engines required the language of analysis for error bounds, series expansions, and algorithmic schemes, and the book repeatedly returns to Cambridge debates to explain how improved notation and pedagogy catalyzed his mechanical designs.
Astronomy and navigation created powerful demand for accurate tables in the 1820s. Babbage helped found the Astronomical Society of London in 1820 (later the Royal Astronomical Society), aligning observational needs with computational supply. The Nautical Almanac, the Board of Longitude (abolished 1828), and observatories at Greenwich and abroad depended on reliable numbers for ephemerides and navigation. Passages situates the Difference Engine as an instrument serving this scientific-industrial state: improved tables would reduce maritime risk and commercial loss. By aligning a machine with national needs—astronomy, geodesy, and surveying—Babbage positioned his work within broader British efforts to standardize and systematize knowledge critical to commerce and empire.
The British government’s funding of the Difference Engine between 1823 and 1842 forms the book’s central historical drama. In 1823, after Babbage proposed a machine to compute and print mathematical tables by the method of differences, the Treasury granted initial support; over the next two decades, public expenditure on the project rose to roughly £17,000, a very substantial sum. Babbage employed the master engineer Joseph Clement, whose exceptional workshop skills advanced precision engineering—improved lathes, planers, and gauges—indispensable to early nineteenth-century machine-making. However, by 1834, disputes arose: Clement demanded payment for moving his workshop and resisted relocating equipment to Babbage’s purpose-built facility in Dorset Street. Work stalled amid contractual ambiguity, rising costs, and shifting priorities within government. The political context changed too: ministries fell and returned; fiscal caution and skepticism about speculative science hardened. Despite partial construction of an advanced calculating section, the Treasury formally canceled support in 1842, concluding the cost and risks outweighed anticipated benefits. Passages narrates these events with dates, letters, and meetings, presenting them as a case study in how administrative timidity and poor project governance can derail transformative technology. Babbage links workshop economics to national policy, arguing that Britain forfeited leadership not for lack of ingenuity but because of patronage, fragmented responsibility, and procurement habits ill-suited to pioneering research. The chronology—1823 grant, 1834 rupture with Clement, 1842 termination—structures the book’s critique of public science funding and its defense of mechanical computation’s promise.
Babbage’s Analytical Engine, conceived around 1834, extended beyond table-making to general symbolic manipulation using a “store” (memory) and “mill” (processor). International engagement sharpened the project. In 1840, Babbage lectured in Turin before the Reale Accademia delle Scienze; Luigi Federico Menabrea produced a French account (1842), which Augusta Ada King, Countess of Lovelace, translated and annotated in 1843, adding algorithmic examples and conceptual insights. Passages emphasizes this European network—Turin and London exchanging ideas—to show how the engine grew from British mechanical skill and continental mathematical method. The book frames the Analytical Engine as a product of transnational science and as Britain’s missed opportunity to institutionalize programmable computation.
Institutional politics in London shaped scientific practice. Babbage was elected Fellow of the Royal Society in 1816, yet he assailed its governance in The Decline of Science in England (1830), criticizing social prestige over merit. The British Association for the Advancement of Science (founded 1831 in York) sought to redistribute authority, promote provincial science, and regularize research funding. Passages revisits these controversies, naming presidents, committees, and procedures to demonstrate how patronage and election practices could throttle innovation. The book thereby mirrors broader reforms in Victorian associational life, arguing for transparent peer evaluation and public accountability in the allocation of status, medals, and money.
Industrialization and labor unrest formed the backdrop to Babbage’s 1832 treatise On the Economy of Machinery and Manufactures. The Luddite disturbances (1811–1816), the Factory Act of 1833, and urban migration sharpened debates about mechanization, wages, and skill. Babbage documented factory workflows, cost accounting, and the division of labor—the “Babbage principle” that assigns simpler tasks to cheaper labor—giving concrete examples from workshops and mills. In Passages, these observations reappear as the social logic behind calculating engines: to mechanize routine operations, minimize error, and print results cheaply. The book thus connects macroeconomic transformation with the engineering of cognition, showing how industrial discipline informed the design of automatic calculation.
The statistical movement institutionalized quantitative governance. The Statistical Society of London (founded 1834; later Royal Statistical Society) and the General Register Office (1837) underpinned vital statistics, with figures like William Farr advancing mortality analysis. Cholera epidemics (notably 1832) demanded reliable data and numerical reasoning in public health. Babbage, a founder of the Statistical Society, championed numerical evidence for policy. Passages links his engines to this administrative arithmetic: printed, error-checked tables could guide pensions, insurance, and sanitary reforms. The book recalls actuarial work and life tables to show how computation stood at the nexus of statecraft and commerce, promising efficient administration if bureaucracy would invest in accuracy.
The Great Exhibition of 1851 in Hyde Park’s Crystal Palace displayed international industrial prowess under Prince Albert’s patronage. Machine tools, steam engines, and precision instruments embodied a celebratory ideology of progress. Babbage, who had long demonstrated parts of the Difference Engine to visitors, used the exhibition’s influx to London to renew conversations with foreign savants, engineers, and administrators. In Passages, he contrasts the Exhibition’s triumphant narrative with the state’s earlier retreat from his project, arguing that genuine leadership requires sustained investment, not spectacular showcases. The event becomes a mirror: Britain could display marvels, yet failed—he believed—to institutionalize the most transformative computational one.
Urban order and policing were central Victorian concerns. The Metropolitan Police were established in 1829, and expanding crowds, traffic, and street entertainments tested regulation. Babbage waged a well-known campaign against street musicians—especially organ grinders—arguing they disrupted work and scientific thought. Passages recounts petitions, magistrates, and Home Office correspondence, embedding his private grievances in the public question of noise, nuisance, and the governance of common spaces. By detailing statutes and cases, the book reflects the era’s negotiation between individual liberty and urban discipline. Babbage’s stance, however idiosyncratic, exposes how productivity ethics and middle-class sensibilities shaped Victorian regulatory politics.
International diffusion of his ideas reached a milestone with the Scheutz Difference Engine, built by Georg and Edvard Scheutz in Sweden in the 1850s. Inspired by Babbage, they presented their machine at the 1855 Exposition Universelle in Paris. In 1859 the British Government purchased a Scheutz engine for the General Register Office to compute and print life tables under William Farr. Passages notes this trajectory to show that foreign initiative and British administrative need converged once a working, cheaper embodiment existed. The episode illustrates a theme of the book: Britain’s institutions hesitated at the prototype stage but adopted when a finished artifact proved utility, often after others bore the development risk.
Mid-century communications and security concerns raised the profile of ciphers. While Friedrich Kasiski published the first general solution to polyalphabetic substitution in 1863, Babbage had independently broken the so-called Vigenère cipher earlier in the 1850s but did not formally publish. Passages alludes to this episode, placing private cryptanalytic work within the wider context of empire, telegraphy, and military intelligence during conflicts such as the Crimean War (1853–1856). The book uses the story to argue that innovative, methodical reasoning—akin to algorithmic decomposition—could serve the state, and that recognition structures often failed to capture or reward such strategically valuable, if confidential, achievements.
Administrative reform gained momentum with the Northcote–Trevelyan Report (1854), advocating merit-based civil service recruitment and clear lines of responsibility. These proposals directly addressed problems Babbage described: patronage, diffused accountability, and inefficient procurement. Passages frames his conflicts with the Treasury and learned societies as symptomatic of a wider governance deficit that reformers sought to cure. By citing committees, minutes, and procedures, Babbage aligns his personal narrative with a national movement toward bureaucratic rationalization. The book thereby situates mechanical calculation within the logic of modern administration: standardized processes, audited costs, and transparent authority—conditions he believed essential for public support of advanced research.
Passages functions as a social and political critique by exposing how class deference and patronage distorted scientific judgment. Babbage documents instances where titled influence outweighed technical merit in elections, awards, and funding, implicating both the Royal Society and government offices. He highlights how urban nuisances, tolerated for entertainment, undermined professional work, reflecting a city that privileged spectacle over productivity. The narrative argues that industrial society’s benefits—precision, standardization, and accountability—should govern institutions as well as factories. In recounting failed negotiations, he indicts opaque decision-making that squandered public funds without delivering public goods, urging a shift from sociability and ceremony to measurable competence.
The book also critiques economic and social inequities exacerbated by rapid industrialization. Babbage accepts mechanization’s efficiencies but demands policies that fairly distribute its gains through accurate statistics, reliable tables, and prudent state investment. His admiration for disciplined labor organization contrasts with contempt for wasteful bureaucratic routines, revealing a politics of improvement rather than laissez-faire complacency. By narrating the Difference Engine’s fate, he exposes systemic risk aversion that privileged immediate savings over long-term national capability. Passages thus interrogates Victorian progress, revealing how class privilege, institutional inertia, and urban disorder impeded a more equitable, knowledge-based society that his engines, and the numerical governance they promised, were meant to advance.
Author Biography
Charles Babbage (1791–1871) was a British mathematician, engineer, and public intellectual whose designs for mechanical computing machines earned him a reputation as a pioneer of the modern computer. Working in the early to mid-nineteenth century, he sought to remove human error from numerical tables used in navigation, astronomy, and finance. He moved fluently between pure mathematics, practical engineering, political economy, and public reform. His proposals for the Difference Engine and the Analytical Engine outlined, for the first time, a general architecture for automatic calculation. Through influential books and leadership in scientific societies, he embedded computation within broader currents of industrialization and professional science.
Educated at Cambridge in the 1810s, Babbage studied first at Trinity College before transferring to Peterhouse, where he completed his degree. With contemporaries such as John Herschel and George Peacock, he formed the Analytical Society to promote the continental calculus of Leibniz and Lagrange over prevailing British practices. Their advocacy for clear notation and rigorous analysis shaped his mathematical outlook and his belief that organization could advance science. He read Laplace and other French authors closely, and his early writings reflected a desire to modernize British mathematics. In his twenties he was elected to leading learned societies, consolidating a national reputation.
In the 1820s Babbage joined efforts to professionalize British science. He helped to establish the Astronomical Society (later the Royal Astronomical Society) and promoted systematic data collection and statistics. His interest in instrumentation, metrology, and industrial processes complemented his mathematical work. During this period he began experimenting with mechanical methods for computing and checking numerical tables, a practical need in astronomy, navigation, and insurance. He obtained government support to pursue a large-scale calculating machine and, late in the decade, accepted the Lucasian Professorship of Mathematics at Cambridge. Administrative roles did not displace his engineering ambitions, which increasingly dominated his time.
The Difference Engine was conceived to tabulate polynomial functions using the method of finite differences, and to print results to avoid transcription mistakes. Babbage engaged skilled craftsmen, notably the engineer Joseph Clement, and produced significant portions and test assemblies. The project encountered escalating costs, technical challenges, and disputes over workshop arrangements and ownership of tooling. Government funding, initially supportive, became cautious and was withdrawn in the early 1840s. Although the first engine was never completed, Babbage later designed a refined Difference Engine No. 2, drawing on lessons from earlier trials and aiming for greater simplicity and manufacturability.
While the tabulating machine addressed specific classes of functions, Babbage’s more audacious Analytical Engine, formulated in the late 1830s and 1840s, outlined a general-purpose, programmable mechanical computer. Inspired in part by the punched-card control of the Jacquard loom, its architecture separated a “store” for data from a “mill” for operations and allowed conditional branching and loops. The design remained on paper and in partial models, but its conceptual reach proved lasting. In 1843 Ada Lovelace translated an Italian account of the engine and appended extensive Notes, including a procedure for calculating Bernoulli numbers, widely regarded as the first published algorithm for such a machine.
Babbage’s books extended his influence beyond engineering. On the Economy of Machinery and Manufactures (early 1830s) analyzed factory organization, division of labor, costs, and technological innovation, and was read by economists, managers, and reformers. The Ninth Bridgewater Treatise (late 1830s) considered natural theology in light of scientific law, reflecting his engagement with philosophical debates. His memoir Passages from the Life of a Philosopher (1860s) offers a detailed account of his projects and frustrations. He also wrote on statistics, railway safety and signaling, and postal systems, and undertook cryptanalytic investigations of polyalphabetic ciphers, much of which remained unpublished during his lifetime.
In later years Babbage continued to refine engine designs and cultivate manufacturers capable of precision work, even as he saw no full machine completed. He died in the early 1870s. Twentieth-century historians and computer pioneers increasingly recognized his architectures as a profound anticipation of digital computation. The Science Museum in London demonstrated their practicality by constructing a working Difference Engine No. 2, from his plans, in the late twentieth century and subsequently its printing mechanism. Today Babbage is read as a foundational figure in computing history and as a penetrating analyst of industrial organization, with ideas that continue to illuminate technology’s social dimensions.
Passages from the Life of a Philosopher
CHAPTER I. MY ANCESTORS.
WHAT is there in a name? It is merely an empty basket, until you put something into it. My earliest visit to the Continent taught me the value of such a basket, filled with the name of my venerable friend the first Herschel, ere yet my younger friend his son, had adorned his distinguished patronymic with the additional laurels of his own well-earned fame.
The inheritance of a celebrated name is not, however, without its disadvantages. This truth I never found more fully appreciated, nor more admirably expressed, than in a conversation with the son of Filangieri, the author of the {2} celebrated Treatise on Legislation, with whom I became acquainted at Naples, and in whose company I visited several of the most interesting institutions of that capital.
In the course of one of our drives, I alluded to the advantages of inheriting a distinguished name, as in the case of the second Herschel. His remark was, “For my own part, I think it a great disadvantage. Such a man must feel in the position of one inheriting a vast estate, so deeply mortgaged that he can never hope, by any efforts of his own, to redeem it.”
Without reverting to the philosophic, but unromantic, views of our origin taken by Darwin, I shall pass over the long history of our progress from a monad up to man, and commence tracing my ancestry as the world generally do: namely, as soon as there is the slightest ground for conjecture. Although I have contended for the Mosaic date of the creation of man as long as I decently could, and have even endeavoured to explain away1 some of the facts relied upon to prove man’s long anterior origin; yet I must admit that the continual accumulation of evidence probably will, at last, compel me to acknowledge that, in this single instance, the writings of Moses may have been misapprehended.
1 On the remains of human art, mixed with the bones of extinct races of animals. Proceedings of the Royal Society, 26th May, 1859.
Let us, therefore, take for granted that man and certain extinct races of animals lived together, thousands of years before Adam. We find, at that period, a race who formed knives, and hammers, and arrow-heads out of flint. Now, considering my own inveterate habit of contriving tools, it is more probable that I should derive my passion by hereditary transmission from these original tool-makers, than from any other inferior race existing at that period. {3}
Many years ago I met a very agreeable party at Mr. Rogers’ table. Somebody introduced the subject of ancestry. I remarked that most people are reluctant to acknowledge as their father or grandfather, any person who had committed a dishonest action or a crime. But that no one ever scrupled to be proud of a remote ancestor, even though he might have been a thief or a murderer. Various remarks were made, and reasons assigned, for this tendency of the educated mind. I then turned to my next neighbour, Sir Robert H. Inglis, and asked him what he would do, supposing he possessed undoubted documents, that he was lineally descended from Cain.
Sir Robert said he was at that moment proposing to himself the very same question. After some consideration, he said he should burn them; and then inquired what I should do in the same circumstances. My reply was, that I should preserve them: but simply because I thought the preservation of any fact might ultimately be useful.
I possess no evidence that I am descended from Cain. If any herald suppose that there may be such a presumption, I think it must arise from his confounding Cain with Tubal Cain[1], who was a great worker in iron. Still, however he might argue that, the probabilities are in favour of his opinion: for I, too, work in iron. But a friend of mine, to whose kind criticisms I am much indebted, suggests that as Tubal Cain invented the Organ, this probability is opposed to the former one.
The next step in my pedigree is to determine whence the origin of my modern family name.
Some have supposed it to be derived from the cry of sheep. If so, that would point to a descent from the Shepherd Kings. Others have supposed it is derived from the name of a place called Bab or Babb, as we have, in the West of England, Bab {4} Tor, Babbacombe, &c. But this is evidently erroneous; for, when a people took possession of a desert country, its various localities could possess no names; consequently, the colonists could not take names from the country to which they migrated, but would very naturally give their own names to the several lands they appropriated: “mais revenons à nos moutons.”
How my blood was transmitted to me through more modern races, is quite immaterial, seeing the admitted antiquity of the flint-workers.
In recent times, that is, since the Conquest, my knowledge of the history of my family is limited by the unfortunate omission of my name from the roll of William’s followers. Those who are curious about the subject, and are idlers, may, if they think it worth while, search all the parish registers in the West of England and elsewhere.
The light I can throw upon it is not great, and rests on a few documents, and on family tradition. During the past four generations I have no surviving collateral relatives of my own name.
The name of Babbage is not uncommon in the West of England. One day during my boyhood, I observed it over a small grocer’s shop, whilst riding through the town of Chudley. I dismounted, went into the shop, purchased some figs, and found a very old man of whom I made inquiry as to his family. He had not a good memory himself, but his wife told me that his name was Babb when she married him, and that it was only during the last twenty years he had adopted the name of Babbage, which, the old man thought, sounded better. Of course I told his wife that I entirely agreed with her husband, and thought him a very sensible fellow.
The craft most frequently practised by my ancestors seems {5} to have been that of a goldsmith, although several are believed to have practised less dignified trades.
In the time of Henry the Eighth one of my ancestors, together with a hundred men, were taken prisoners at the siege of Calais.
When William the Third landed in Torbay, another ancestor of mine, a yeoman possessing some small estate, undertook to distribute his proclamations. For this bit of high treason he was rewarded with a silver medal, which I well remember seeing, when I was a boy. It had descended to a very venerable and truthful old lady, an unmarried aunt, the historian of our family, on whose authority the identity of the medal I saw with that given by King William must rest.
Another ancestor married one of two daughters, the only children of a wealthy physician, Dr. Burthogge, an intimate friend and correspondent of John Locke.
Somewhere about 1700 a member of my family, one Richard Babbage, who appears to have been a very wild fellow, having tried his hand at various trades, and given them all up, offended a wealthy relative.
To punish this idleness, his relative entailed all his large estates upon eleven different people, after whom he gave it to this Richard Babbage, who, had there been no entail, would have taken them as heir-at-law.
Ten of these lives had dropped, and the eleventh was in a consumption, when Richard Babbage took it into his head to go off to America with Bamfylde Moore Carew, the King of the Beggars.
The last only of the eleven lives existed when he embarked, and that life expired within twelve months after Richard Babbage sailed. The estates remained in possession of the representatives of the eleventh in the entail. {6}
If it could have been proved that Richard Babbage had survived twelve months after his voyage to America, these estates would have remained in my own branch of the family.
I possess a letter from Richard Babbage, dated on board the ship in which he sailed for America.
In the year 1773 it became necessary to sell a portion of this property, for the purpose of building a church at Ashbrenton. A private Act of Parliament was passed for that purpose, in which the rights of the true heir were reserved.
CHAPTER II. CHILDHOOD.
FROM my earliest years I had a great desire to inquire into the causes of all those little things and events which astonish the childish mind. At a later period I commenced the still more important inquiry into those laws of thought and those aids which assist the human mind in passing from received knowledge to that other knowledge then unknown to our race. I now think it fit to record some of those views to which, at various periods of my life, my reasoning has led me. Truth only has been the object of my search, and I am not conscious of ever having turned aside in my inquiries from any fear of the conclusions to which they might lead.
As it may be interesting to some of those who will hereafter read these lines, I shall briefly mention a few events of my earliest, and even of my childish years. My parents being born at a certain period of history, and in a certain latitude and longitude, of course followed the religion {8} of their country. They brought me up in the Protestant form of the Christian faith. My excellent mother taught me the usual forms of my daily and nightly prayer; and neither in my father nor my mother was there any mixture of bigotry and intolerance on the one hand, nor on the other of that unbecoming and familiar mode of addressing the Almighty which afterwards so much disgusted me in my youthful years.
My invariable question on receiving any new toy, was “Mamma, what is inside of it?” Until this information was obtained those around me had no repose, and the toy itself, I have been told, was generally broken open if the answer did not satisfy my own little ideas of the “fitness of things.”
Earliest Recollections.
Two events which impressed themselves forcibly on my memory happened, I think, previously to my eighth year.
When about five years old, I was walking with my nurse, who had in her arms an infant brother of mine, across London Bridge, holding, as I thought, by her apron. I was looking at the ships in the river. On turning round to speak to her, I found that my nurse was not there, and that I was alone upon London Bridge. My mother had always impressed upon me the necessity of great caution in passing any street-crossing: I went on, therefore, quietly until I reached Tooley Street, where I remained watching the passing vehicles, in order to find a safe opportunity of crossing that very busy street.
In the mean time the nurse, having lost one of her charges, had gone to the crier[2], who proceeded immediately to call, by the ringing of his bell, the attention of the public to the fact that a young philosopher was lost, and to the still more important fact that five shillings would be the reward of his fortunate discoverer. I well remember sitting on the steps of {9} the door of the linendraper’s shop on the opposite corner of Tooley Street, when the gold-laced crier was making proclamation of my loss; but I was too much occupied with eating some pears to attend to what he was saying.
The fact was, that one of the men in the linendraper’s shop, observing a little child by itself, went over to it, and asked what it wanted. Finding that it had lost its nurse, he brought it across the street, gave it some pears, and placed it on the steps at the door: having asked my name, the shopkeeper found it to be that of one of his own customers. He accordingly sent off a messenger, who announced to my mother the finding of young Pickle before she was aware of his loss.
Those who delight in observing coincidences may perhaps account for the following singular one. Several years ago when the houses in Tooley Street were being pulled down, I believe to make room for the new railway terminus, I happened to pass along the very spot on which I had been lost in my infancy. A slate of the largest size, called a Duchess,2 was thrown from the roof of one of the houses, and penetrated into the earth close to my feet.
2 There exists an aristocracy even amongst slates, perhaps from their occupying the most elevated position in every house. Small ones are called Ladies, a larger size Countesses, and the biggest of all are Duchesses.
The other event, which I believe happened some time after the one just related, is as follows. I give it from memory, as I have always repeated it.
I was walking with my nurse and my brother in a public garden, called Montpelier Gardens, in Walworth. On returning through the private road leading to the gardens, I gathered and swallowed some dark berries very like black currants:—these were poisonous. {10}
On my return home, I recollect being placed between my father’s knees, and his giving me a glass of castor oil, which I took from his hand.
My father at that time possessed a collection of pictures. He sat on a chair on the right hand side of the chimney-piece in the breakfast room, under a fine picture of our Saviour taken down from the cross. On the opposite wall was a still-celebrated “Interior of Antwerp Cathedral.”
In after-life I several times mentioned the subject both to my father and to my mother; but neither of them had the slightest recollection of the matter.
Having suffered in health at the age of five years, and again at that of ten by violent fevers, from which I was with difficulty saved, I was sent into Devonshire and placed under the care of a clergyman (who kept a school at Alphington, near Exeter), with instructions to attend to my health; but, not to press too much knowledge upon me: a mission which he faithfully accomplished. Perhaps great idleness may have led to some of my childish reasonings.
Relations of ghost stories often circulate amongst children, and also of visitations from the devil in a personal form. Of course I shared the belief of my comrades, but still had some doubts of the existence of these personages, although I greatly feared their appearance. Once, in conjunction with a companion, I frightened another boy, bigger than myself, with some pretended ghost; how prepared or how represented by natural objects I do not now remember: I believe it was by the accidental passing shadows of some external objects upon the walls of our common bedroom.
The effect of this on my playfellow was painful; he was much frightened for several days; and it naturally occurred to me, after some time, that as I had deluded him with ghosts, {11} I might myself have been deluded by older persons, and that, after all, it might be a doubtful point whether ghost or devil ever really existed. I gathered all the information I could on the subject from the other boys, and was soon informed that there was a peculiar process by which the devil might be raised and become personally visible. I carefully collected from the traditions of different boys the visible forms in which the Prince of Darkness had been recorded to have appeared. Amongst them were—
A rabbit,An owl,A black cat, very frequently,A raven,A man with a cloven foot, also frequent.After long thinking over the subject, although checked by a belief that the inquiry was wicked, my curiosity at length over-balanced my fears, and I resolved to attempt to raise the devil. Naughty people, I was told, had made written compacts with the devil, and had signed them with their names written in their own blood. These had become very rich and great men during their life, a fact which might be well known. But, after death, they were described as having suffered and continuing to suffer physical torments throughout eternity, another fact which, to my uninstructed mind, it seemed difficult to prove.
As I only desired an interview with the gentleman in black simply to convince my senses of his existence, I declined adopting the legal forms of a bond, and preferred one more resembling that of leaving a visiting card, when, if not at home, I might expect the satisfaction of a return of the visit by the devil in person. {12}
Accordingly, having selected a promising locality, I went one evening towards dusk up into a deserted garret. Having closed the door, and I believe opened the window, I proceeded to cut my finger and draw a circle on the floor with the blood which flowed from the incision.
I then placed myself in the centre of the circle, and either said or read the Lord’s Prayer backwards. This I accomplished at first with some trepidation and in great fear towards the close of the scene. I then stood still in the centre of that magic and superstitious circle, looking with intense anxiety in all directions, especially at the window and at the chimney. Fortunately for myself, and for the reader also, if he is interested in this narrative, no owl or black cat or unlucky raven came into the room.
In either case my then weakened frame might have expiated this foolish experiment by its own extinction, or by the alienation of that too curious spirit which controlled its feeble powers.
After waiting some time for my expected but dreaded visitor, I, in some degree, recovered my self-possession, and leaving the circle of my incantation, I gradually opened the door and gently closing it, descended the stairs, at first slowly, and by degrees much more quickly. I then rejoined my companions, but said nothing whatever of my recent attempt. After supper the boys retired to bed. When we were in bed and the candle removed, I proceeded as usual to repeat my prayers silently to myself. After the few first sentences of the Lord’s Prayer, I found that I had forgotten a sentence, and could not go on to the conclusion. This alarmed me very much, and having repeated another prayer or hymn, I remained long awake, and very unhappy. I thought that this forgetfulness was a punishment inflicted {13} upon me by the Almighty, and that I was a wicked little boy for having attempted to satisfy myself about the existence of a devil. The next night my memory was more faithful, and my prayers went on as usual. Still, however, I was unhappy, and continued to brood over the inquiry. My uninstructed faculties led me from doubts of the existence of a devil to doubts of the book and the religion which asserted him to be a living being. My sense of justice (whether it be innate or acquired) led me to believe that it was impossible that an almighty and all-merciful God could punish me, a poor little boy, with eternal torments because I had anxiously taken the only means I knew of to verify the truth or falsehood of the religion I had been taught. I thought over these things for a long time, and, in my own childish mind, wished and prayed that God would tell me what was true. After long meditation, I resolved to make an experiment to settle the question. I thought, if it was really of such immense importance to me here and hereafter to believe rightly, that the Almighty would not consign me to eternal misery because, after trying all means that I could devise, I was unable to know the truth. I took an odd mode of making the experiment; I resolved that at a certain hour of a certain day I would go to a certain room in the house, and that if I found the door open, I would believe the Bible; but that if it were closed, I should conclude that it was not true. I remember well that the observation was made, but I have no recollection as to the state of the door. I presume it was found open from the circumstance that, for many years after, I was no longer troubled by doubts, and indeed went through the usual religious forms with very little thought about their origin.
At length, as time went on, my bodily health was restored {14} by my native air: my mind, however, receiving but little instruction, began, I imagine, to prey upon itself—such at least I infer to have been the case from the following circumstance. One day, when uninterested in the sports of my little companions, I had retired into the shrubbery and was leaning my head, supported by my left arm, upon the lower branch of a thorn-tree. Listless and unoccupied, I imagined I had a head-ache. After a time I perceived, lying on the ground just under me, a small bright bit of metal. I instantly seized the precious discovery, and turning it over, examined both sides. I immediately concluded that I had discovered some valuable treasure, and running away to my deserted companions, showed them my golden coin. The little company became greatly excited, and declared that it must be gold, and that it was a piece of money of great value. We ran off to get the opinion of the usher; but whether he partook of the delusion, or we acquired our knowledge from the higher authority of the master, I know not. I only recollect the entire dissipation of my head-ache, and then my ultimate great disappointment when it was pronounced, upon the undoubted authority of the village doctor, that the square piece of brass I had found was a half-dram weight which had escaped from the box of a pair of medical scales. This little incident had an important effect upon my after-life. I reflected upon the extraordinary fact, that my head-ache had been entirely cured by the discovery of the piece of brass. Although I may not have put into words the principle, that occupation of the mind is such a source of pleasure[1q] that it can relieve even the pain of a head-ache; yet I am sure it practically gave an additional stimulus to me in many a difficult inquiry. Some few years after, when suffering under a form of tooth-ache, not acute though tediously {15} wearing, I often had recourse to a volume of Don Quixote, and still more frequently to one of Robinson Crusoe. Although at first it required a painful effort of attention, yet it almost always happened, after a time, that I had forgotten the moderate pain in the overpowering interest of the novel.
My most intimate companion and friend was a boy named Dacres, the son of Admiral Richard Dacres. We had often talked over such questions as those I have mentioned in this chapter, and we had made an agreement that whichever died first should, if possible, appear to the other after death, in order to satisfy the survivor about their solution.
After a year or two my young friend entered the navy, but we kept up our friendship, and when he was ashore I saw him frequently. He was in a ship of eighty guns at the passage of the Dardanelles, under the command of Sir Thomas Duckworth. Ultimately he was sent home in charge of a prize-ship, in which he suffered the severest hardships during a long and tempestuous voyage, and then died of consumption.
I saw him a few days before his death, at the age of about eighteen. We talked of former times, but neither of us mentioned the compact. I believe it occurred to his mind: it was certainly strongly present to my own.
He died a few days after. On the evening of that day I retired to my own room, which was partially detached from the house by an intervening conservatory. I sat up until after midnight, endeavouring to read, but found it impossible to fix my attention on any subject, except the overpowering feeling of curiosity, which absorbed my mind. I then undressed and went into bed; but sleep was entirely banished. I had previously carefully examined whether any cat, bird, or living animal might be accidentally concealed in my room, {16} and I had studied the forms of the furniture lest they should in the darkness mislead me.
I passed a night of perfect sleeplessness. The distant clock and a faithful dog, just outside my own door, produced the only sounds which disturbed the intense silence of that anxious night.
CHAPTER III. BOYHOOD.
DURING my boyhood my mother took me to several exhibitions of machinery. I well remember one of them in Hanover Square, by a man who called himself Merlin. I was so greatly interested in it, that the Exhibitor remarked the circumstance, and after explaining some of the objects to which the public had access, proposed to my mother to take me up to his workshop, where I should see still more wonderful automata. We accordingly ascended to the attic. There were two uncovered female figures of silver, about twelve inches high.
One of these walked or rather glided along a space of about four feet, when she turned round and went back to her original place. She used an eye-glass occasionally, and bowed frequently, as if recognizing her acquaintances. The motions of her limbs were singularly graceful.
The other silver figure was an admirable danseuse, with a bird on the fore finger of her right hand, which wagged its tail, flapped its wings, and opened its beak. This lady attitudinized in a most fascinating manner. Her eyes were full of imagination, and irresistible. {18}
These silver figures were the chef-d’œuvres of the artist: they had cost him years of unwearied labour, and were not even then finished.
After I left Devonshire I was placed at a school in the neighbourhood of London, in which there were about thirty boys.
My first experience was unfortunate, and probably gave an unfavourable turn to my whole career during my residence of three years.
