Charles Sanders Peirce quotes - page 2
Mathematics is distinguished from all other sciences except only ethics, in standing in no need of ethics.
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
The essence of belief is the establishment of a habit; and different beliefs are distinguished by the different modes of action to which they give rise.
Charles Sanders Peirce
It is impossible not to envy the man who can dismiss reason, although we know how it must turn out at last.
Charles Sanders Peirce
Generality is, indeed, an indispensable ingredient of reality; for mere individual existence or actuality without any regularity whatever is a nullity. Chaos is pure nothing.
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
It is the man of science, eager to have his every opinion regenerated, his every idea rationalized, by drinking at the fountain of fact, and devoting all the energies of his life to the cult of truth, not as he understands it, but as he does not yet understand it, that ought properly to be called a philosopher.
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
The development of the human mind has practically extinguished all feelings, except a few sporadic kinds, [like] sound, colors, smells, warmth, etc., which now appear to be disconnected and separate.
Charles Sanders Peirce
The next simplest feature that is common to all that comes before the mind, and consequently, the second category, is the element of Struggle.
Charles Sanders Peirce
Second, by this and other means we are driven to perceive, what is quite evident in itself, that instantaneous feelings flow together in a continuum of feeling, which has in a modified degree the peculiar vivacity of feeling and has gained generality. And in reference to such general ideas, or continua of feeling, the difficulties about resemblance and suggestion and reference to the external, cease to have any force.
Charles Sanders Peirce
What distinct meaning can attach to saying that an idea in the past in any way affects an idea in the future, from which it is completely detached?
Charles Sanders Peirce
From these two immediate perceptions, we gain a mediate, or inferential perception of the relation of all four instants. This mediate perception is objectively, or as to the object being represented, spread over the four instants; but subjectively, or as itself the subject of duration, it is completely embraced in the second moment. (The reader will observe that I use the word instant to mean a point in time, and moment to mean an infinitesimal duration.
Charles Sanders Peirce
Let me now try to gather up all these odds and ends of commentary and restate the law of mind, in a unitary way.
Charles Sanders Peirce
If the sensation that precedes the present by half a second were still immediately before me, then on the same principle, the sensation preceding that would be immediately present, and so on ad infinitum. Now, since there is a time [period], say a year, at the end of which an idea is no longer ipso facto present, it follows that this is true of any finite interval, however short.
Charles Sanders Peirce
The old dualistic notion of mind and matter, so prominent in Cartesianism, as two radically different kinds of substance, will hardly find defenders to-day. Rejecting this, we are driven to some form of hylopathy, otherwise called monism.
Charles Sanders Peirce
Let us not pretend to doubt in philosophy what we do not doubt in our hearts.
Charles Sanders Peirce
Since space is continuous, it follows that there must be an immediate community of feeling between parts of mind infinitesimally close together. Without this, I believe it would have been impossible for any co-ordination to be established in the action of the nerve-matter of one brain.
Charles Sanders Peirce
I think that I have succeeded in making it clear that this doctrine gives room for explanations of many facts which without it are absolutely and hopelessly inexplicable; and further that it carries along with it the following doctrines: first, a logical realism of the most pronounced type; second, objective idealism; third, tychism, with its consequent thoroughgoing evolutionism. We also notice that the doctrine presents no hindrences to spiritual influences, such as some philosophies are felt to do.
Charles Sanders Peirce
The third category of which I come now to speak is precisely that whose reality is denied by nominalism. For although nominalism is not credited with any extraordinarily lofty appreciation of the powers of the human soul, yet it attributes to it a power of originating a kind of ideas the like of which Omnipotence has failed to create as real objects, and those general conceptions which men will never cease to consider the glory of the human intellect must, according to any consistent nominalism, be entirely wanting in the mind of Deity.
Charles Sanders Peirce
You are of all my friends the one who illustrates pragmatism in its most needful forms. You are a jewel of pragmatism.
Charles Sanders Peirce
A finite interval of time generally contains an innumerable series of feelings; and when these become welded together in association the result is a general idea.
