Science Quotes by William James (28 quotes)

'Facts' are the bounds of human knowledge, set for it, not by it.
— William James
'On Some Hegelisms' (1882). In The Will to Believe and Other Essays in Popular Philosophy (1897), 271.
Science quotes on:  |  Fact (325)  |  Knowledge (679)

A Beethoven string-quartet is truly, as some one has said, a scraping of horses' tails on cats' bowels, and may be exhaustively described in such terms; but the application of this description in no way precludes the simultaneous applicability of an entirely different description.
— William James
The Sentiment of Rationality (1882), 76.
Science quotes on:  |  Beethoven_Ludwig (4)  |  Description (40)

All our scientific and philosophic ideals are altars to unknown gods.
— William James
'The Dilemma of Determinism' (1884). In The Will to Believe and Other Essays in Popular Philosophy (1897), 147.
Science quotes on:  |  Ideal (26)

Consciousness... does not appear to itself chopped up in bits. Such words as 'chain' or 'train' do not describe it fitly as it presents itself in the first instance. It is nothing jointed; it flows. A 'river' or a 'stream' are the metaphors by which it is most naturally described. In talking of it hereafter, let us call it the stream of thought, of consciousness, or of subjective life.
Source of the expression 'stream of consciousness'.
— William James
The Principles of Psychology (1890), Vol. 1, 239.
Science quotes on:  |  Consciousness (36)  |  Nomenclature (102)

Could the young but realize how soon they will become mere walking bundles of habits, they would give more heed to their conduct while in the plastic state. We are spinning our own fates, good or evil, and never to be undone.
— William James

First... a new theory is attacked as absurd; then it is admitted to be true, but obvious and insignificant; finally it is seen to be so important that its adversaries claim that they themselves discovered it.
— William James
'Pragmatism's Conception of Truth', in Pragmatism: A New Name for some Old Ways of Thinking, Popular Lectures on Philosophy (1907), 198.

For this we must make automatic and habitual, as early as possible, as many useful actions as we can, and guard against the growing into ways that are likely to be disadvantageous to us, as we should guard against the plague?
— William James

Genius, in truth, means little more than the faculty of perceiving in an unhabitual way.
— William James
In Psychology (1904), 328.
Science quotes on:  |  Faculty (21)  |  Genius (92)  |  Perception (21)  |  Truth (450)

Habit is thus the enormous fly-wheel of society, its most precious conservative agent. It alone is what keeps us all within the bounds of ordinance, and saves the children of fortune from the envious uprisings of the poor. It alone prevents the hardest and most repulsive walks of life from being deserted by those brought up to tread therein.
— William James
'The Laws of Habit', The Popular Science Monthly (Feb 1887), 447.

Many persons nowadays seem to think that any conclusion must be very scientific if the arguments in favor of it are derived from twitching of frogs' legs—especially if the frogs are decapitated—and that—on the other hand—any doctrine chiefly vouched for by the feelings of human beings—with heads on their shoulders—must be benighted and superstitious.
— William James
Pragmatism: A New Name for Old Ways of Thinking (1907)
Science quotes on:  |  Conclusion (74)  |  Frog (24)  |  Scientific (55)

Nature in her unfathomable designs had mixed us of clay and flame, of brain and mind, that the two things hang indubitably together and determine each other's being but how or why, no mortal may ever know.
— William James
Principles of Psychology (1918), 200.
Science quotes on:  |  Mankind (111)  |  Nature (534)

Objective evidence and certitude are doubtless very fine ideals to play with, but where on this moonlit and dream-visited planet are they found?
— William James
'The Will to Believe' (1896). In The Will to Believe and Other Essays in Popular Philosophy (1897), 14.
Science quotes on:  |  Certainty (59)  |  Evidence (83)  |  Ideal (26)

Our natural way of thinking about these coarser emotions is that the mental perception of some fact excites the mental affection called the emotion, and that this latter state of mind gives rise to the bodily expression. My theory, on the contrary, is that the bodily changes follow directly the perception of the exciting fact, and that our feeling of the same changes as they occur IS the emotion. Common-sense says, we lose our fortune, are sorry and weep; we meet a bear, are frightened and run; we are insulted by a rival, are angry and strike. The hypothesis here to be defended says that this order of sequence is incorrect, that the one mental state is not immediately induced by the other, that the bodily manifestations must first be interposed between, and that the more rational statement is that we feel sorry because we cry, angry because we strike, afraid because we tremble, and not that we cry, strike, or tremble, because we are sorry, angry, or fearful, as the case may be. Without the bodily states following on the perception, the latter would be purely cognitive in form, pale, colorless, destitute of emotional warmth. We might then see the bear, and judge it best to run, receive the insult and deem it right to strike, but we should not actually feel afraid or angry.
— William James
The Principles or Psychology (1890), Vol. 2, 449-50.

Plasticity, then, in the wide sense of the word, means the possession of a structure weak enough to yield to an influence, but strong enough not to yield all at once. Each relatively stable phase of equilibrium in such a structure is marked by what we may call a new set of habits. Organic matter, especially nervous tissue, seems endowed with a very extraordinary degree of plasticity of this sort ; so that we may without hesitation lay down as our first proposition the following, that the phenomena of habit in living beings are due to plasticity of the organic materials of which their bodies are composed.
— William James

Science as such assuredly has no authority, for she can only say what is, not what is not.
— William James
'Is Life Worth Living?' (1895). In The Will to Believe and Other Essays in Popular Philosophy (1897), 56.
Science quotes on:  |  Proof (136)  |  Science (875)

Science can tell us what exists; but to compare the worths, both of what exists and of what does not exist, we must consult not science, but what Pascal calls our heart.
— William James

The art of being wise is the art of knowing what to overlook.
— William James

Science quotes on:  |  Art (80)  |  Knowledge (679)  |  Overlook (6)  |  Wisdom (91)

The first effect of the mind growing cultivated is that processes once multiple get to be performed in a single act. Lazarus has called this the progressive “condensation” of thought. ... Steps really sink from sight. An advanced thinker sees the relations of his topics is such masses and so instantaneously that when he comes to explain to younger minds it is often hard ... Bowditch, who translated and annotated Laplace's Mιchanique Cιleste, said that whenever his author prefaced a proposition by the words “it is evident,” he knew that many hours of hard study lay before him.
— William James

The first thing the intellect does with an object is to class it along with something else. But any object that is infinitely important to us and awakens our devotion feels to us also as if it must be sui generis and unique. Probably a crab would be filled with a sense of personal outrage if it could hear us class it without ado or apology as a crustacean, and thus dispose of it. 'I am no such thing,' it would say; 'I am MYSELF, MYSELF alone.
— William James

The function of ignoring, of inattention, is as vital a factor in mental progress as the function of attention itself.

The God whom science recognizes must be a God of universal laws exclusively, a God who does a wholesale, not a retail business. He cannot accommodate his processes to the convenience of individuals.
— William James
The Varieties of Religious Experience: A Study in Human Nature (1902), 493-5.
Science quotes on:  |  God (234)  |  Law (273)  |  Science And Religion (159)

The history of philosophy is to a great extent that of a certain clash of human temperaments... I will write these traits down in two columns. I think you will practically recognize the two types of mental make-up that I mean if I head the columns by the titles 'tender-minded' and 'tough-minded' respectively.
THE TENDER-MINDED. Rationalistic (going by 'principles'), Intellectualistic, Idealistic, Optimistic, Religious, Free-willist, Monistic, Dogmatical.
THE TOUGH-MINDED. Empiricist (going by 'facts'), Sensationalistic, Materialistic, Pessimistic, Irreligious, Fatalistic, Pluralistic, Sceptical.
— William James

The self-same atoms which, chaotically dispersed, made the nebula, now, jammed and temporarily caught in peculiar positions, form our brains; and the 'evolution' of brains, if understood, would be simply the account of how the atoms came to be so caught and jammed.
— William James
Principles of Psychology (1918), 146.
Science quotes on:  |  Atom (164)  |  Brain (106)  |  Nebula (13)

The traditional psychology talks like one who should say a river consists of nothing but pailsful, spoonsful, quartpotsful, barrelsful, and other moulded forms of water. Even were the pails and the pots all actually standing in the stream, still between them the free water would continue to flow. It is just this free water of consciousness that psychologists resolutely overlook. Every definite image in the mind is steeped and dyed in the free water that flows round it. With it goes the sense of its relations, near and remote, the dying echo of whence it came to us, the dawning sense of whither it is to lead.
— William James
'On Some Omissions of Introspective Psychology', Mind (1884), 9, 16.
Science quotes on:  |  Consciousness (36)  |  Psychology (69)

We have to be ready to live today by what truth we can get today and be ready tomorrow to call it falsehood.
— William James

We [may] answer the question: “Why is snow white?” by saying, “For the same reason that soap-suds or whipped eggs are white”—in other words, instead of giving the reason for a fact, we give another example of the same fact. This offering a similar instance, instead of a reason, has often been criticised as one of the forms of logical depravity in men. But manifestly it is not a perverse act of thought, but only an incomplete one. Furnishing parallel cases is the necessary first step towards abstracting the reason imbedded in them all.
— William James
In The Principles of Psychology (1918), Vol. 2, 363-364.

Whatever universe a professor believes in must at any rate be a universe that lends itself to lengthy discourse. A universe definable in two sentences is something for which the professorial intellect has no use. No faith in anything of that cheap kind!

When two minds of a high order, interested in kindred subjects, come together, their conversation is chiefly remarkable for the summariness of its allusions and the rapidity of its transitions. Before one of them is half through a sentence the other knows his meaning and replies. ... His mental lungs breathe more deeply, in an atmosphere more broad and vast...

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
