It has always been the task of formal education to set up behavior which would prove useful or enjoyable later in a student's life.

Art is thought, and thought only gives the world an appearance of order to anyone weak enough to be convinced by its show.

The only justification for our concepts and system of concepts is that they serve to represent the complex of our experiences; beyond this they have no legitimacy. I am convinced that the philosophers have had a harmful effect upon the progress of scientific thinking in removing certain fundamental concepts from the domain of empiricism, where they are under our control, to the intangible heights of the a priori. For even if it should appear that the universe of ideas cannot be deduced from experience by logical means, but is, in a sense, a creation of the human mind, without which no science is possible, nevertheless the universe of ideas is just as little independent of the nature of our experience as clothes are of the form of the human body. This is particularly true of our concepts of time and space, which physicists have been obliged by the facts to bring down from the Olympus of the a priori in order to adjust them and put them in a serviceable condition.

Blessed is the healthy nature; it is the coherent, sweetly co-operative, not incoherent, self-distracting, self-destructive one!

And yet it will be obvious that it is difficult to really know of what sort each thing is.

Being asked where in Greece he saw good men, he replied, "Good men nowhere, but good boys at Sparta."

If you wish to be loved, love.

If a captive mind is unaware of being in prison, it is living in error. If it has recognized the fact, even for the tenth of a second, and then quickly forgotten it in order to avoid suffering, it is living in falsehood. Men of the most brilliant intelligence can be born, live and die in error and falsehood. In them, intelligence is neither a good, nor even an asset. The difference between more or less intelligent men is like the difference between criminals condemned to life imprisonment in smaller or larger cells. The intelligent man who is proud of his intelligence is like a condemned man who is proud of his large cell.

What will be the attitude of communism to existing nationalities? The nationalities of the peoples associating themselves in accordance with the principle of community will be compelled to mingle with each other as a result of this association and thereby to dissolve themselves, just as the various estate and class distinctions must disappear through the abolition of their basis, private property.

On James's view, "true" resembles "good" or "rational" in being a normative notion, a compliment paid to sentences that seem to be paying their way and that fit with other sentences which are doing so.

Now, to-day, this moment, is our chance to choose the right side. God is holding back to give us that chance. It will not last for ever. We must take it or leave it.

We were laboring under a dropsical fulness of circulating medium. Nearly all of it is now called in by the banks, who have the regulation of the safety-valves of our fortunes, and who condense and explode them at their will. Lands in this State cannot now be sold for a year's rent; and unless our Legislature have wisdom enough to effect a remedy by a gradual diminution only of the medium, there will be a general revolution of property in this state.

I have no patience with those who say that sexual excitement is shameful and that venereal stimuli have their origin not in nature, but in sin. Nothing is so far from the truth. As if marriage, whose function cannot be fulfilled without these incitements, did not rise above blame. In other living creatures, where do these incitements come from? From nature or from sin? From nature, of course. It must borne in mind that in the apetites of the body there is very little difference between man and other living creatures. Finally, we defile by our imagination what of its own nature is fair and holy. If we were willing to evaluate things not according to the opinion of the crowd, but according to nature itself, how is it less repulsive to eat, chew, digest, evacuate, and sleep after the fashion of dumb animals, than to enjoy lawful and permitted carnal relations?

The end of the republic is to enervate and to weaken all other bodies so as to increase its own body.

Great men are they who see that spiritual is stronger than any material force, that thoughts rule the world. No hope so bright but is the beginning of its own fulfillment. 

The institution of religion exists only to keep mankind in order, and to make men merit the goodness of God by their virtue. Everything in a religion which does not tend towards this goal must be considered foreign or dangerous.

Facts are the materials of science, but all Facts involve Ideas. Since, in observing Facts, we cannot exclude Ideas, we must, for the purposes of science, take care that the Ideas are clear and rigorously applied.

Though he made a joke when asked to do the right thing, he always did it. He was so much more in earnest than he appeared. He did not do himself justice.

This spirit thrusts itself forward, confident of commendation and esteem. It is superior to all, monarch of all it surveys; hence it should be subservient to nothing, finding no task too heavy, and nothing strong enough to weigh down the shoulders of a man.

What is it, in your opinion, to be a great nobleman? It is to be master of several objects that men covet, and thus to be able to satisfy the wants and the desires of many. It is these wants and these desires that attract them towards you, and that make them submit to you: were it not for these, they would not even look at you; but they hope, by these services... to obtain from you some part of the good which they desire, and of which they see that you have the disposal.

Every time a man is begotten and born, the clock of human life is wound up anew to repeat once more its same old tune that has already been played innumerable times, movement by movement and measure by measure, with insignificant variations.

A physician, after he had felt the pulse of Pausanias, and considered his constitution, saying, "He ails nothing," "It is because, sir," he replied, "I use none of your physic."

Two elements must therefore be rooted out once for all-the fear of future suffering, and the recollection of past suffering; since the latter no longer concerns me, and the former concerns me not yet.

...God commanded in the law [Deut. 22:22-24] that adulterers be stoned . . . The temporal sword and government should therefore still put adulterers to death . . . Where the government is negligent and lax, however, and fails to inflict the death penalty, the adulterer may betake himself to a far country and there remarry if he is unable to remain continent. But it would be better to put him to death, lest a bad example be set . . .

Survive in such a way that you avoid limiting others who are also trying to survive. We all live in limited systems. This is the core of ethics.

I think of the course of human history as a long, swelling, increasingly polyphonic poem - a poem that leads up to nothing save itself. When the species is extinct, "human nature's total message" will not be a set of propositions, but a set of vocabularies - the more, and the more various, the better.

First of all, principles should be general. That is, it must be possible to formulate them without use of what would be intuitively recognized as proper names, or rigged definite descriptions.

Treat your inferiors as you would be treated by your betters.

So far as it goes, a small thing may give an analogy of great things, and show the tracks of knowledge.

Stories on digital platforms like Facebook or Instagram are not genuine stories. They have no narrative duration. Rather, they are just sequences of momentary impressions that do not tell us anything.

Among these widely differing families of men, the first that attracts attention, the superior in intelligence, in power, and in enjoyment, is the white, or European, the MAN pre-eminently so called, below him appear the Negro and the Indian.

As long as one does not call his own position into question but regards it as absolute, while interpreting his opponents' ideas as a mere function of the social positions they occupy, the decisive step forward has not yet been taken.

All media of communications are cliches serving to enlarge man's scope of action, his patterns of associations and awareness. These media create environments that numb our powers of attention by sheer pervasiveness.

Humiliate the reason and distort the soul...

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.

Cato the elder wondered how that city was preserved wherein a fish was sold for more than an ox.

In physical reality one cause does not produce a given effect, but a multitude of distinct causes contribute to produce it, without our having any means of discriminating the part of each of them. ...Causes which have produced a certain effect will never be reproduced except approximately.

Even if the whole world were to fall to pieces, the unity of the psyche would never be shattered. And the wider and more numerous the fissures on the surface, the more the unity is strengthened in the depths.

It would be silly, of course, to be either 'for' or 'against' modernity tout court, not only because it is pointless to try to stop the development of technology, science, and economic rationality, but because both modernity and antimodernity may be expressed in barbarous and antihuman terms.

It is a conceded fact that woman is being reared as a sex commodity, and yet she is kept in absolute ignorance of the meaning and importance of sex.

Nor is there any embarrassment in the fact that we're ridiculous, isn't it true? For it's actually so, we are ridiculous, light-minded, with bad habits, we're bored, we don't know how to look, how to understand, we're all like that, all, you, and I, and they! Now, you're not offended when I tell you to your face that you're ridiculous? And if so, aren't you material? You know, in my opinion it's sometimes even good to be ridiculous, if not better: we can the sooner forgive each other, the sooner humble ourselves; we can't understand everything at once, we can't start right out with perfection! To achieve perfection, one must first begin by not understanding many things! And if we understand too quickly, we may not understand well. This I tell you, you, who have already been able to understand. .. and not understand ... so much. I'm not afraid for you now.

The more powerful and original a mind, the more it will incline towards the religion of solitude.

There are no solutions, only cowardice masquerading as such.

For my part, I travel not to go anywhere, but to go. I travel for travel's sake. The great affair is to move.

The First [Friend] is the alter ego, the man who first reveals to you that you are not alone in the world by turning out (beyond hope) to share all your most secret delights. There is nothing to be overcome in making him your friend; he and you join like raindrops on a window. But the Second Friend is the man who disagrees with you about everything... Of course he shares your interests; otherwise he would not become your friend at all. But he has approached them all at a different angle. he has read all the right books but has got the wrong thing out of every one... How can he be so nearly right, and yet, invariably, just not right? He is as fascinating (and infuriating) as a woman.

The concept of guilt is found most powerfully developed even in the most primitive communal forms which we know: ... the man is guilty who violates one of the original laws which dominate the society and which are mostly derived from a divine founder; the boy who is accepted into the tribal community and learns its laws, which bind him thenceforth, learns to promise; this promise is often given under the sign of death, which is symbolically carried out on the boy, with a symbolical rebirth.
