More quotes by 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
Every new concept first comes to the mind in a judgment.
Charles Sanders Peirce
All the progress we have made in philosophy ... is the result of that methodical skepticism which is the element of human freedom.
Charles Sanders Peirce
It is not knowing, but the love of learning, that characterizes the scientific man.
Charles Sanders Peirce
Mathematics is distinguished from all other sciences except only ethics, in standing in no need of ethics.
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
All the greatest achievements of mind have been beyond the power of unaided individuals.
Charles Sanders Peirce
The a priori method is distinguished for its comfortable conclusions. It is the nature of the process to adopt whatever belief weare inclined to, and there are certain flatteries to the vanity of man which we all believe by nature, until we are awakened from our pleasing dream by rough facts.
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
We do not really think, we are barely conscious, until something goes wrong.
Charles Sanders Peirce
It is certain that the only hope of retroductive reasoning ever reaching the truth is that there may be some natural tendency toward an agreement between the ideas which suggest themselves to the human mind and those which are concerned in the laws of nature.
Charles Sanders Peirce
Truth is that concordance of an abstract statement with the ideal limit towards which endless investigation would tend to bring scientific belief, which concordance the abstract statement may possess by virtue of the confession of its inaccuracy and one-sidedness, and this confession is an essential ingredient of truth.
Charles Sanders Peirce
We should chiefly depend not upon that department of the soul which is most superficial and fallible (our reason), but upon that department that is deep and sure, which is instinct.
Charles Sanders Peirce
We shall do better to abandon the whole attempt to learn the truthunless we can trust to the human mind's having such a powerof guessing right that before very many hypotheses shall have been tried, intelligent guessing may be expected to lead us to one which will support all tests, leaving the vast majority of possible hypotheses unexamined.
Charles Sanders Peirce
We cannot begin with complete doubt.
Charles Sanders Peirce
Our whole past experience is continually in our consciousness, though most of it sunk to a great depth of dimness. I think of consciousness as a bottomless lake, whose waters seem transparent, yet into which we can clearly see but a little way.
Charles Sanders Peirce
All the evolution we know of proceeds from the vague to the definite.
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
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
