This entry joins Claude Shannon's 1938 master's thesis on relay and switching circuits with his 1948 paper A Mathematical Theory of Communication. The thesis made a decisive engineering move: it showed that Boolean algebra could describe and simplify relay circuits.
An Investigation of the Laws of Thought is George Boole's attempt to express logic, probability, and reasoning in mathematical form. The book begins from a bold premise: the operations of the mind in reasoning can be studied through symbols and laws analogous to those of algebra.
As We May Think is a speculative essay about the problem of intellectual abundance. Written at the end of World War II, it asks what scientists should do when their wartime energies turn toward peace and when the record of human knowledge has grown too large for traditional methods of indexing, filing, and retrieval.
Freud's late essay, in German Das Unbehagen in der Kultur ('the uneasiness in culture'), asks why civilized people, who have built so much for their own protection, are so often unhappy. It is written in eight short chapters in a conversational, self-questioning style.
Cybernetics presents one of the twentieth century's boldest attempts to unite machines, organisms, and societies under a single vocabulary of control, communication, feedback, and information. Wiener begins from wartime problems of prediction, especially the effort to anticipate the path of aircraft quickly enough for anti-aircraft fire.
De Materia Medica is an ancient pharmacopoeia: a systematic guide to plants, animals, minerals, wines, oils and manufactured preparations used as medicines. Dioscorides does not write a narrative.
Destruction and Creation and the OODA Loop Briefings gather John Boyd's strategic thought from thermodynamics and epistemology to conflict, command, and adaptation. Destruction and Creation argues that organisms and organizations must break apart old mental concepts and rebuild new ones in order to cope with a changing reality.
The Discourse on the Method of Rightly Conducting One's Reason and Seeking Truth in the Sciences was published anonymously in Leiden in 1637 as a preface to three scientific essays, the Dioptrics, the Meteors and the Geometry. Descartes wrote it in French rather than Latin so that readers using their natural reason, including women, could judge it without scholastic training, and he presented it not as a treatise but as a history or fable of his own mind.
Dracula is told through journals, letters, phonograph diaries, telegrams and newspaper cuttings assembled by its characters. Jonathan Harker, a young English solicitor, travels to Transylvania to arrange the purchase of a London property, Carfax, for Count Dracula.
First Draft of a Report on the EDVAC is not a polished monograph but a technical memorandum whose influence exceeds its form. Written in 1945 for the Electronic Discrete Variable Automatic Computer project, it describes a general-purpose electronic digital computer in which numerical data and operating instructions occupy the same high-speed memory.
Kokoro, a word meaning heart, mind or the core of things, is in three parts. In the first, 'Sensei and I', a young university student in Tokyo meets an older man at the seaside resort of Kamakura and is drawn to him, calling him Sensei, 'teacher'.
Kraepelin's Lectures on Clinical Psychiatry introduces readers to psychiatric diagnosis through bedside cases and disease course. Rather than beginning with abstract definitions, the lectures proceed from patients: mood disturbance, excitement, confusion, delusions, hallucinations, deterioration, alcoholism, epilepsy, paralysis, dementia praecox, manic-depressive insanity, and other clinical groupings.
Charcot's lectures show clinical neurology becoming a public method: observe signs, localize lesions, correlate symptoms with anatomy, and teach by cases. The English volumes gather Salpetriere lectures on spinal cord disease, paralysis, tremor, sclerosis, locomotor ataxia, hysteria, epilepsy, and related nervous disorders.
Leibniz's logical writings on binary arithmetic and universal character are scattered across essays, letters, drafts, and memoranda rather than gathered in a single finished book. Their unity lies in a dream: reasoning might be made clearer, more reliable, and more inventive by a symbolic language whose elements combine according to rules.
Griesinger gives nineteenth-century psychiatry a somatic and medical program. Mental Pathology and Therapeutics treats insanity as a disorder of the brain, even while admitting how little pathological anatomy could yet prove.
Natural History: A Selection introduces one of antiquity’s great encyclopedic minds. Pliny wants to collect nature and human use together: stars, lands, peoples, animals, plants, metals, pigments, stones, medicines, marvels and technologies all belong to one vast inventory.
Ada Lovelace's Notes on Menabrea's Sketch of the Analytical Engine begin as an act of translation and become a theory of computation. Luigi Menabrea had published a French account of Charles Babbage's proposed Analytical Engine after hearing Babbage lecture in Turin.
The Novum Organum ('new instrument') is the second and only substantially completed part of Bacon's projected Instauratio Magna, a six-part plan to rebuild human knowledge from its foundations. Its title throws down a challenge to the Organon, the collection of Aristotle's logical works that had governed university teaching for centuries.
This paired entry brings together Alan Turing's 1936 paper On Computable Numbers, with an Application to the Entscheidungsproblem and his 1950 essay Computing Machinery and Intelligence. The first paper attacks a precise mathematical problem: what does it mean for a number or function to be computable?
On Formally Undecidable Propositions is one of the decisive works in the history of logic. Godel addresses the dream that mathematics might be placed on a complete and consistent formal foundation, a dream associated with Hilbert's program.
On the Origin of Species argues that species are not fixed, separately created kinds but populations changed over time by variation, inheritance, struggle, natural selection, and descent with modification. Darwin begins with variation under domestication, using pigeons, livestock, and cultivated plants to show how small differences can be preserved and accumulated.
On the Road is narrated by Sal Paradise, a young writer living with his aunt in New Jersey, and records a series of journeys back and forth across the United States and into Mexico between 1947 and 1950. The engine of the book is Dean Moriarty, a fast-talking, car-stealing, endlessly restless young man from Denver who seems to Sal the embodiment of a wild, joyous American energy.
Passages from the Life of a Philosopher is Charles Babbage's late memoir of invention, public controversy, and scientific administration. It is not a continuous autobiography so much as a set of argued recollections.
Newton's Principia sets out the mathematical principles of natural philosophy and shows that the same laws can explain terrestrial motion and celestial order. The work begins with definitions of mass, quantity of motion, inertia, impressed force, centripetal force, absolute and relative space, and absolute and relative time.
Sixty Stories is Donald Barthelme's own selection of his short fiction from roughly two decades, drawn from collections such as Come Back, Dr. Caligari, Unspeakable Practices, Unnatural Acts, City Life, Sadness, Amateurs and Great Days, together with some previously uncollected pieces.
The Art of the Commonplace gathers Wendell Berry's agrarian essays on land, household, work, food, technology, economy, conservation, and the moral scale of community. The collection's title points to Berry's method: he resists abstraction by returning arguments to farms, watersheds, kitchens, tools, soil, neighbors, and inherited obligations.
The Communist Manifesto presents modern history as the history of class struggle and casts the bourgeoisie as both revolutionary and exploitative. Marx and Engels argue that capitalism has dissolved feudal relations, expanded world markets, concentrated production, remade family and nation, and subjected older loyalties to cash exchange.
The Descent of Man applies evolutionary theory to human beings and develops Darwin's account of sexual selection. Darwin argues that humans share ancestry with other animals and that differences between human and animal mental faculties are differences of degree rather than absolute kind.
The River War: An Historical Account of the Reconquest of the Soudan is the young Winston Churchill's history of the Anglo-Egyptian campaigns of 1896–1899 that destroyed the Mahdist state in the Sudan. Churchill begins with geography and the Nile, which he presents as the thread on which the whole story hangs, and then with the rebellion of Muhammad Ahmad, a Dongolawi boat-builder's son and Sufi ascetic who proclaimed himself the Mahdi in 1881.
We is presented as the diary or record of D-503, mathematician and builder of the spaceship Integral in the OneState, a glass-walled totalitarian society ruled by the Benefactor. Citizens, called Numbers, live by tables of hours, regulated labor, monitored sex, prescribed walks and transparent architecture.
