More quotes by Charles Sanders Peirce
All the evolution we know of proceeds from the vague to the definite.
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
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
... and it is probably that there is some secret here which remains to be discovered.
Charles Sanders Peirce
It is not knowing, but the love of learning, that characterizes the scientific man.
Charles Sanders Peirce
Truly, that reason upon which we plume ourselves, though it may answer for little things, yet for great decisions is hardly surer than a toss up.
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
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
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
The entire universe is perfused with signs, if it is not composed exclusively of signs.
Charles Sanders Peirce
I define a Sign as anything which is so determined by something else, called its Object, and so determines an effect upon a person, which effect I call its Interpretant, that the latter is thereby mediately determined by the former.
Charles Sanders Peirce
Consider what effects that might conceivably have practical bearings you conceive the objects of your conception to have. Then, your conception of those effects is the whole of your conception of the object.
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
Another characteristic of mathematical thought is that it can have no success where it cannot generalize.
Charles Sanders Peirce
A quality is something capable of being completely embodied. A law never can be embodied in its character as a law except by determining a habit. A quality is how something may or might have been. A law is how an endless future must continue to be.
Charles Sanders Peirce
Whenever a man acts purposively, he acts under a belief in some experimental phenomenon. Consequently, the sum of the experimental phenomena that a proposition implies makes up its entire bearing upon human conduct.
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
If liberty of speech is to be untrammeled from the grosser forms of constraint, the uniformity of opinion will be secured by a moral terrorism to which the respectability of society will give its thorough approval.
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
There is a kink in my damned brain that prevents me from thinking as other people think.
Charles Sanders Peirce
