"Deductive" Quotes from Famous Books



... eighteenth century failed to destroy this illiberality owing to the method of the Scotch philosophers. The school which arose was in reaction against the dominant theological spirit; but its method was deductive not inductive. Now, the inductive method, which ascends from experience to theory is anti-theological. The deductive reasons down from theories whose validity is assumed; it is the method of theology itself. In Scotland the ...

... than Heldon Foyle the danger of jumping to conclusions. Inferences, however clever, however sound they may seem when they are drawn, are apt to lead one astray. The detective who habitually used the deductive method would spend a great deal of his time exploring blind alleys.

... conviction that scientific investigation is not, as many people seem to suppose, some kind of modern black art. I say that you might easily gather this impression from the manner in which many persons speak of scientific inquiry, or talk about inductive and deductive philosophy, or the principles of the "Baconian philosophy." I do protest that, of the vast number of cants in this world, there are none, to my mind, so contemptible as the pseudoscientific cant which is talked about ...

... down to the foundations of scientific certainty, but, in his 'Principes de Philosophie,' indicated where the goal of physical science really lay. However, Descartes was an eminent mathematician, and it would seem that the bent of his mind led him to overestimate the value of deductive reasoning from general principles, as much as Bacon had underestimated it.

From this view of the nature of the science, it follows at once that the method to be pursued must be that called by Mill the physical or concrete deductive, which starts from certain known causes, investigates their consequences and verifies or tests the result by comparison with facts of experience. It may, perhaps, be thought that Cairnes gives too little attention to the effects of the organism ...

... the pretensions of the Church depended for success upon a public opinion which was hard to move. Not because the average layman was critical or anti-clerical, but because he was illogical and unimaginative, he remained cold to any programme of reform which could only be justified by long trains of deductive reasoning; his natural impulse was against violent innovations, and he felt rather than argued that the State, as the ultimate guarantee of social order, must be maintained even at some cost of theological consistency. Until he could be convinced that high moral issues and his own ...

... studies which enter into ordinary education do not discipline the mind in this way. Mathematical training is almost purely deductive. The mathematician starts with a few simple propositions, the proof of which is so obvious that they are called self-evident, and the rest of his work consists of subtle deductions from them.

That the sun does not move about the earth, that the earth is but a speck in space, that heaven cannot be above nor hell beneath, these are thoughts which have consequences. Instead of the old deductive method, that of the mediaeval Aristotelianism, which had been worse than fruitless in the study of nature, men now set out with a great enthusiasm to study facts, and to observe their laws. Modern optics, acoustics, chemistry, geology, zoology, psychology and medicine, ...

The purely inductive and descriptive study of the manuscripts does not prove the existence of such a personage, and we must decline to admit him as the result of deductive reasoning. In this so-called "young god", we miss, first of all, a characteristic mark, a distinct peculiarity such as belongs to all the figures of gods in the manuscripts without exception and by which he could be recognized. Except his so-called youthfulness, ...

... philosophical aspect, consists in the reassertion of the importance of the individual instance as against the generalisation. All our social, political, moral problems are being approached in a new spirit, in an inquiring and experimental spirit, which has small respect for abstract principles and deductive rules.

... "mysticism," as a mode of life aiming at the realisation of the presence of God, is as distinct from scholasticism as empiricism is from rationalism, or "tough-minded" philosophy (to use JAMES' happy phrase) is from "tender-minded". But no philosophy can be absolutely and purely deductive. It must start from certain empirically determined facts. A man might be an extreme empiricist in religion (i.e. a mystic), and yet might attempt to deduce all other forms of knowledge from the results of his religious experiences, never caring to gather experience ...

But it makes all the difference which end you start from, the facts or the theory: whether your method is a posteriori or a priori; inductive or deductive; scientific or obscurantist. And Christianity follows the scientific method of starting with the facts. In this lies the justification of its claim to be a religion at once universal and life-giving. It is universal because facts are the common property ...

It is based upon the broadest induction, and it is verified by the most constant, regular, and universal of deductive processes.

This way of treating political theory enabled the writer to assume an air of certitude and precision, which led narrow deductive minds completely captive.

A certain amount of generalization is desirable, but its over-emphasis develops bad habits of mind on the part of the student, and requires radical readjustment of his ideas in subsequent field investigations. To retain ...

Putting these, then, at least for the moment, to one side, we find ourselves face to face with two great and indisputable facts that everywhere force themselves on the attention and compel consideration. ...

Mr. Cromering had been much impressed—he said so—with the logical skill and masterly deductive powers by which Colwyn had reconstructed the hidden events of the night of the murder, like an Owen reconstructing the extinct moa from a single bone, but he was loath to accept that part of the theory which seemed to throw doubt on ...

The practical induction of Bacon, Earl of Verulam, was the death-warrant of the fruitless deductive philosophy which had culminated in the vagaries of Scholasticism. The Declaration of Independence and the Federation of the States were the iconoclast which slew the phantom of the divine necessity of kings. It is thus evident that ...

The sciences would then have been wholly independent of one another; each would have rested entirely on its own inductions, and if deductive at all, would have drawn its deductions from premises exclusively furnished by itself. The fact, however, is otherwise. The relation which really subsists between different kinds of phaenomena, enables the ...

Plato is the great exponent of dialectic, or the reciprocal affinities and necessities of ideas. Aristotle is the founder of deductive logic.

It gave little consideration to man in himself, and said little of the supernatural. Everything was speculative in nature, hypothetical in proposition, and deductive in argument. The Greek mind, departing from its dependence upon mythology, began boldly to assert its ability to find out nature, but ended in a scepticism as to its power to ascertain certainty. There was a final determination as to the distinction ...

This should be done inductively and in an investigative spirit. Our whole system of education seems somewhat vitiated by the deductive attitude and method of teaching—the assuming of theories handed down by the past, without investigation or verification. This is the kind of teaching which has paralyzed China for untold generations. The easiest thing to do is to accept something which somebody else has formulated and then, ...

Thus the effect, where we can best watch its causes, seems mainly produced by a desire for a definite object—in some cases a serious and sensible desire, in others an idle one, in others, again, a mistaken one; and sometimes by a blunder ...
