This is a translation of Hippolyte Taine’s French study of John Stuart Mill, published in London and Edinburgh in 1873 in a version by T. D. Haye. Taine, one of the great nineteenth-century French critics and historians of philosophy, sets out to explain Mill’s thought to a French-reading public and then to argue with it. The book is not a neutral digest but a confrontation: exposition first, then a sustained counter-argument mounted from the French side of the philosophical divide.
The Core Argument
Taine’s central claim is that Mill’s philosophy is the most complete and rigorous expression of a single national temper — the English genius for experience. Mill builds everything from particular facts and their connections, refusing substances, causes, and hidden essences. Taine admires the honesty and precision of this procedure, and he grants its starting point: we know nothing directly of minds or bodies, only transient internal states. But he argues that Mill’s system leaves out the one operation that makes knowledge possible — abstraction, the power of isolating elements within facts and treating them separately. Once abstraction is restored, Taine claims, definitions, proofs, axioms, and induction all change character, and a metaphysics becomes possible again.
Inside the Book
Exposition of Mill’s Philosophy
Taine opens with a scene rather than an argument. At Oxford, during a meeting of the British Association, he falls in with a young Englishman and visits the New Museum, where specimens fill the halls, models of machinery work, lectures are delivered, and “God save the Queen” is sung. Taine admires the zeal and the organizing genius but misses general ideas; the learned men strike him as foremen trading recipes for tanning leather. He tells his friend that England has learned men but no thinkers, and that the national God — guardian of morality, final judge, the most important personage in the country — keeps them from reasoning about causes. He notes the cant and intolerance this produces: a Sanskrit scholar obliged to find the worship of a moral god in the Vedas, a proclamation against Sunday card-playing, a throne speech that must mention Divine Providence. The friend answers that England does have thinkers, and names Stuart Mill: the political writer whose On Liberty decides for individual freedom as Rousseau’s Social Contract decided for state despotism, the economist who subordinates production to man, the logician of his own school. Mill is no system-monger; he proceeds step by step over particular facts, with the astuteness and patience of a lawyer, allied to Locke, Newton, Hume, and Comte. Asked whether Mill has a single governing conception of nature and mind, the friend says yes, but that it must be discovered. Taine takes up the task.
The exposition proper begins with logic, the science whose subject is all other sciences. After we have traversed stars, earth, heat, gravity, minerals, plants, animals, and human events, there remain the classifications and theories — an order of beings and an order of thoughts representing them. Taine then follows Mill through the theory of definition. Mill holds that no definition expresses a thing’s whole nature; every proposition states only part of it. We should give up the hope of a mysterious primitive being behind properties and leave such entities to Duns Scotus. There are no definitions of things, only of names: a phrase does not tell us what a horse is, it explains the meaning of a word. Definition passes from the term to its attributes, then to the sensations underlying them, reducing compound to simple and words to facts. Geometrical definitions seem to yield new truths only because they contain a hidden postulate alongside a convention.
On proof, Mill attacks the syllogism. “All men are mortal; Prince Albert is a man; therefore Prince Albert is mortal” teaches nothing new, since the conclusion is already in the premises. Real premises are particular facts — the mortality of John, Thomas, and Company. General propositions are mementos, abbreviated registers; children and animals reason from particular to particular without them. Logicians, Mill says, have given words precedence over facts. Axioms fare no better: they look necessary and fruitful, but mental contemplation is only a displaced experiment, and the contraries of axioms are inconceivable because they are experimental. Induction is therefore the sole key to nature. It concludes that what is true of certain individuals is true of a whole class, and it leads us up to the uniformity of nature rather than starting from it. Experience is the test of experience. Cause means nothing more than invariable succession: the invariable antecedent is cause, the invariable consequent effect, and the real cause is the whole sum of positive and negative conditions. “Necessary” means unconditional. The will offers no different kind of causation; it produces bodily actions as cold produces ice.
Mill’s four methods follow. Agreement: fifty crucibles and fifty solutions all crystallize, and the one common fact — the passage from liquid to solid — is the invariable antecedent. Difference: a bird breathes in air and ceases to breathe plunged into carbonic acid gas; the one differing circumstance is the cause. Residues: the velocity of sound came out faster than calculation allowed, and Laplace found the surplus in heat developed by the condensation of each sonorous wave. Concomitant Variations: earth and pendulum, moon and tide, cannot be suppressed, so their variations are correlated. Taine then walks through Dr. Wells’s theory of dew as a working demonstration — dew defined against rain and fog, coldness of the dewed object established by thermometer, negative cases such as polished metals, variations showing the worst heat conductors most dewed, and three corroborations from deduction, direct experiment, and nature’s own experiment when clouds withdraw. The section closes on the limits of isolation, on deduction, and on the respective provinces of induction and deduction.
Accordance of This Philosophy with the English Mind
The second part turns from exposition to reply, and Taine speaks as an advocate. He grants Mill’s starting point and goes further: there are no substances at all, only systems of facts; substance, force, and metaphysical existences are scholastic remnants and psychological illusions. But then comes the omission. Abstraction — the power of isolating elements of facts and considering them separately — is the origin of language, the parent of religions and philosophies, the real distinction between man and brute. A square yields equal sides and angles; a cylinder yields a rectangle and its revolution; Mill’s twelve hundred pages yield his leading idea. Abstraction does not pass to a new fact but to another aspect of the same fact, from whole to part, as a curve is expressed by an equation. Hence there are instructive judgments not derived from experience, and essential propositions that are not merely verbal.
On definitions, Taine answers that defining a sphere as generated by a revolving semicircle asserts that all its properties derive from this formula; it expresses the essence, the internal primordial cause. True definitions mark the generating quality, and every science aims at one — planetary motion by tangential force and central attraction, chemical bodies by equivalent, living bodies by type. On proof, the mortality of a living man is not proved from John and Peter but from the cause: the human body is an unstable chemical compound. Aristotle is cited — a fact is proved by pointing out its cause — and the syllogism passes from abstract to concrete, from cause to effect. On axioms, Taine deduces them from definitions: describe a straight line as traced by a point moving toward another point only, and two straight lines with two points in common must coincide, enclosing nothing. Axioms are identical propositions, analyses; there is only one axiom, that of identity. This restores absolute and universal knowledge, since one fact includes the other. Induction itself is the triumph of abstraction, not pure experience: cold and dew, liquid-to-solid and crystallization, are abstract facts isolated by subtraction, and induction links abstract antecedent to abstract consequent.
Two moving powers thus govern the mind: experience and abstraction, two kingdoms of complex facts and simple elements, effect and cause, the one deducible from the other. Facts are arbitrary groupings made by our senses; nature is a tapestry seen reversed. We seek laws, real groups and connections, passing from accidental to necessary. Decomposition continues until entirely simple elements, whose decomposition would contradict itself. The axiom of causation, mutilated by Mill, means that everything has a reason and a law, every compound reduces to simples, the product equals its factors, and cause does not differ in nature from effect.
Can we know these first elements? Taine thinks we can, since abstracts are comprised in facts. The German metaphysicians seized the truth of simple notions but ignored our limits; outflanked by infinity of time and space, we find chance at the end of knowledge as at the beginning of postulates. An initial state must be accepted as a pure postulate, and a primitive accidental fact extends its effects everywhere — different planets, compounds, vegetables, animals, races. An ant transported elsewhere would not see the same trees, insects, soil, atmosphere. There is a local, accidental portion in every fact, connected to primitive laws only through an infinite circuit bridged by infinite deductions. The Germans tried to deduce the planetary system, physical and chemical laws, types of life, civilization, and thought from elementary theorems, discarding chance; the void destroyed their edifice. Yet not everything is local: an ant, if it could experiment, might attain physical law, living form, sensation, abstract thought; if it could reason, arithmetic, algebra, geometry, mechanics; if a philosopher, being, nothingness, metaphysics. However limited the mind’s field, it contains universal and absolute truths, since the more general a fact, the fewer objects are needed to meet it. Metaphysics is possible if we remain at a great height, considering only the simplest elements and most general tendencies. Whoever collected the three or four great ideas in which the sciences end — duration and extension, physical laws, chemical types, living species, and Mind, which without falling into quantity reproduces the two others and itself — and showed they must combine as they do, would sketch a metaphysics without encroaching on the positive sciences.
The conclusion gathers the whole: experience and abstraction comprise all the mind’s resources, practical and speculative. The first leads us to consider nature as an assemblage of facts, the other as a system of laws. The exclusive employment of the first is English, of the second German. France, Taine says, holds the place between them: having extended eighteenth-century English ideas, in the nineteenth it can give precision to German ones, restraining, correcting, and completing both types.
Key Ideas
The book turns on a single opposition. On one side stands Mill’s positivism: knowledge reduces to facts and their connections, definition concerns names, proof is a register of particulars, axioms are experimental, cause is invariable succession, and induction is the whole of method. On the other stands Taine’s corrective: abstraction is a real operation, definitions express generating causes, proofs run from cause to effect, axioms are identical propositions deduced from definitions, and induction itself depends on abstract elements isolated from concrete facts. Around this axis cluster Taine’s secondary themes — the national character of philosophies, the difference between the English, German, and French tempers, the possibility of a metaphysics that stays at the level of the simplest elements, and the place of chance at the limits of knowledge.
Themes
Taine’s book is as much a portrait of a civilization as a study of a philosopher. He reads Mill’s logic as the codified form of the English mind: empirical, precise, legalistic, suspicious of causes, at home among particulars. The opening Oxford scene and the running contrast with Germany and France make the argument cultural rather than merely technical. A second theme is the cost of that temper. Taine admires Mill’s honesty but argues that a philosophy built on experience alone cannot account for the very abstractions that make science possible, and so leaves the mind without access to necessary truth. A third theme is mediation. Taine presents France as the nation positioned to complete what England and Germany each do one-sidedly — to give precision to German abstraction while restraining it with English fact. The book’s epilogue, “Oxford at Sunrise,” closes the frame opened at the museum, returning the argument to the place where it began.
Why It Matters
The book matters for two reasons. It is one of the earliest sustained French engagements with Mill’s Logic, written while Mill was still alive and corrected by Mill himself in correspondence — Mill praised the accuracy of the exposition while disputing that his views were especially English, counting twenty a priori and spiritualist philosophers for every partisan of experience. And it is a compact statement of Taine’s own position, the empiricism and abstraction he would carry into his later work. For a reader today it offers something rare: a philosopher of the first rank arguing with another philosopher of the first rank, in prose meant for the general educated public, about what it means to know anything at all.
