More quotes by Charles Sanders Peirce
The consciousness of a general idea has a certain unity of the ego in it, which is identical when it passes from one mind to another. It is, therefore, quite analogous to a person, and indeed, a person is only a particular kind of general idea.
Charles Sanders Peirce
But the extraordinary insight which some persons are able to gain of others from indications so slight that it is difficult to ascertain what they are, is certainly rendered more comprehensible by the view here taken.
Charles Sanders Peirce
When anything is present to the mind, what is the very first and simplest character to be noted in it, in every case, no matter how little elevated the object may be? Certainly, it is its presentness .
Charles Sanders Peirce
Some think to avoid the influence of metaphysical errors, by paying no attention to metaphysics but experience shows that these men beyond all others are held in an iron vice of metaphysical theory, because by theories that they have never called in question.
Charles Sanders Peirce
Another characteristic of mathematical thought is that it can have no success where it cannot generalize.
Charles Sanders Peirce
It is a common observation that those who dwell continually upon their expectations are apt to become oblivious to the requirements of their actual situation.
Charles Sanders Peirce
All the evolution we know of proceeds from the vague to the definite.
Charles Sanders Peirce
Notwithstanding all that has been discovered since Newton's time, his saying that we are little children picking up pretty pebbles on the beach while the whole ocean lies before us unexplored remains substantially as true as ever, and will do so though we shovel up the pebbles by steam shovels and carry them off in carloads.
Charles Sanders Peirce
In all the works on pedagogy that ever I read — and they have been many, big, and heavy — I don't remember that any one has advocated a system of teaching by practical jokes, mostly cruel. That, however, describes the method of our great teacher, Experience.
Charles Sanders Peirce
There never was a sounder logical maxim of scientific procedure than Ockham's razor: Entia non sunt multiplicanda praeter necessitatem. That is to say before you try a complicated hypothesis, you should make quite sure that no simplification of it will explain the facts equally well.
Charles Sanders Peirce
One will meet, for example, the virtual assumption that what is relative to thought cannot be real. But why not, exactly? Red is relative to sight, but the fact that this or that is in that relation to vision that we call being red is not itself relative to sight it is a real fact.
Charles Sanders Peirce
Doubt is an uneasy and dissatisfied state from which we struggle to free ourselves and pass into the state of belief while the latter is a calm and satisfactory state which we do not wish to avoid, or to change to a belief in anything else.
Charles Sanders Peirce
Bad reasoning as well as good reasoning is possible and this fact is the foundation of the practical side of logic.
Charles Sanders Peirce
It is not knowing, but the love of learning, that characterizes the scientific man.
Charles Sanders Peirce
It has never been in my power to study anything, mathematics, ethics, metaphysics, gravitation, thermodynamics, optics, chemistry, comparative anatomy, astronomy, psychology, phonetics, economics, the history of science, whist, men and women, wine, metrology, except as a study of semeiotic .
Charles Sanders Peirce
... and it is probably that there is some secret here which remains to be discovered.
Charles Sanders Peirce
Theology, I am persuaded, derives its initial impulse from a religious wavering for there is quite as much, or more, that is mysterious and calculated to awaken scientific curiosity in the intercourse with God, and it [is] a problem quite analogous to that of theology.
Charles Sanders Peirce
The truth is, that common-sense, or thought as it first emerges above the level of the narrowly practical, is deeply imbued with that bad logical quality to which the epithet metaphysical is commonly applied and nothing can clear it up but a severe course of logic.
Charles Sanders Peirce
Every new concept first comes to the mind in a judgment.
Charles Sanders Peirce
Theoretically, I grant you, there is no possibility of error in necessary reasoning. But to speak thus theoretically, is to uselanguage in a Pickwickian sense. In practice, and in fact, mathematics is not exempt from that liability to error that affects everything that man does.
Charles Sanders Peirce
