Dear youths, I warn you cherish peace divine, And in your hearts lay deep these words of mine.

He was not merely a chip of the old Block, but the old Block itself.

The sensate body possesses an art of interrogating the sensible according to its own wishes, an inspired exegesis The Visible and the Invisible, trans.

We are living in the most destructive and, hence, the most stupid period of the history of our species.

To be acutely conscious is a disease, a real, honest-to-goodness disease.

The way positive reinforcement is carried out is more important than the amount.

A fool is known by his Speech; and a wise man by Silence.

When we assume God to be a guiding principle-well, sure enough, a god is usually characteristic of a certain system of thought or morality. For instance, take the Christian God, the summum bonum: God is love, love being the highest moral principle; and God is spirit, the spirit being the supreme idea of meaning. All our Christian moral concepts derive from such assumptions, and the supreme essence of all of them is what we call God.

Philosophy ... is a science, and as such has no articles of faith; accordingly, in it nothing can be assumed as existing except what is either positively given empirically, or demonstrated through indubitable conclusions.

Neither a person nor a nation can exist without some higher idea. And there is only one higher idea on earth, and it is the idea of the immortality of the human soul, for all other "higher" ideas of life by which humans might live derive from that idea alone.

In the present state of society it appears necessary to go back to first principles in search of the most simple truths, and to dispute with some prevailing prejudice every inch of ground. To clear my way, I must be allowed to ask some plain questions, and the answers will probably appear as unequivocal as the axioms on which reasoning is built; though, when entangled with various motives of action, they are formally contradicted either by the words or conduct of men.

On the frontiers of the self: "What I have suffered, what I am suffering, no one will ever know, not even I."

An arrogant person considers himself perfect. This is the chief harm of arrogance. It interferes with a person's main task in life-becoming a better person.

We should be clear that neither genuine religious nor genuine moral impulses will ever be expressed in terms that tie the two essentially together. If you view religion as necessary for ethics, you've reduced us to the ethical level of 4 year olds. "If you follow these commandments you'll go to heaven, if you don't' you'll burn in hell" is just a spectacular version of the carrots and sticks with which you raise your children.

The three qualities of space and time reciprocally affect and qualify one another in experience. Space is inane save as occupied with active volumes. Pauses are holes when they do not accentuate masses and define figures as individuals. Extension sprawls and finally benumbs if it does not interact with place so as to assume intelligible distribution. Mass is nothing fixed. It contracts and expands, asserts and yields, according to its relations to other spatial and enduring things.... these are then the common properties of the matter of arts because there are general conditions without which an experience is not possible. As we saw earlier, the basic condition is felt relationship between doing and undergoing as the organism and environment interact.

Morally, it is wrong to suppose the source of evil is outside oneself, that one is a vessel of holiness running over with virtue. Such a disposition is the best soil for a hateful and cruel fanaticism. It is as wrong to impute every wickedness to Jews, Freemasons, "intellectuals," as it is to blame all crimes on the bourgeoisie, the nobility, and the powers that were. No; the root of evil is in me as well, and I must take my share of the responsibility and the blame. That was true before the revolution and it is true still.

For already, sometime, I have been a boy and a girl, a shrub, a bird, and a silent fish in the sea.

Revolutionaries do not make revolutions! The revolutionaries are those who know when power is lying in the street and when they can pick it up. Armed uprising by itself has never yet led to revolution.

A wise man never loses anything, if he has himself.

There is nothing more visible than what is secret, and nothing more manifest than what is minute. Therefore the superior man is watchful over himself, when he is alone.

The only thing we are naturally afraid of is pain, or loss of pleasure. And because these are not annexed to any shape, colour, or size of visible objects, we are frighted of none of them, till either we have felt pain from them, or have notions put into us that they will do us harm.

Do not be too timid and squeamish about your actions. All life is an experiment. The more experiments you make the better.

The big advantage of being a chemistry major was the freedom to be tasteless.

They call it "friendship" and "peace," and further "harmony" and "unanimity": for these are all cohesive and unificatory of opposites and dissimilars. Hence they also call it "marriage." And there are also three ages in life.

The highest manifestation of life consists in this: that a being governs its own actions. A being that is always subject to the direction of another is somewhat of a dead thing. Variant translation: Now slavery has a certain likeness to death, hence it is also called civil death. For life is most evident in a thing's moving itself, while what can only be moved by another, seems to be as if dead. But it is manifest that a slave is not moved by himself, but only at his master's command.

He that is not with me is against me: and he that gathereth not with me scattereth.

Yes, truly, it is a great thing for a Nation that it get an articulate voice; that it produce a man who will speak forth melodiously what the heart of it means!

Man must not only make himself: the weightiest thing he has to do is to determine what he is going to be. He is causa sui to the second power.

The first intellectual operation in which I arrived at any proficiency, was dissecting a bad argument, and finding in what part the fallacy lay: and though whatever capacity of this sort I attained was due to the fact that it was an intellectual exercise in which I was most perseveringly drilled by my father, yet it is also true that the school logic, and the mental habits acquired in studying it, were among the principal instruments of this drilling. I am persuaded that nothing, in modern education, tends so much, when properly used, to form exact thinkers, who attach a precise meaning to words and propositions, and are not imposed on by vague, loose, or ambiguous terms. The boasted influence of mathematical studies is nothing to it; for in mathematical processes, none of the real difficulties of correct ratiocination occur.

What is food to one, is to others bitter poison.

Patriots always talk of dying for their country, and never of killing for their country.

"And your education! Is not that also social, and determined by the social conditions under which you educate, by the intervention, direct or indirect, of society, by means of schools, etc.? The Communists have not invented the intervention of society in education; they do but seek to alter the character of that intervention, and to rescue education from the influence of the ruling class."

My main theme is the extension of the nervous system in the electric age, and thus, the complete break with five thousand years of mechanical technology. This I state over and over again. I do not say whether it is a good or bad thing. To do so would be meaningless and arrogant.

Solicitation and effort or conation belong properly to animate beings alone. When they are attributed to other things, they must be taken in a metaphorical sense; but a philosopher should abstain from metaphor.

No differeance without alterity, no alterity without singularity, no singularity without here-now.

I wish to propose for the reader's favourable consideration a doctrine which may, I fear, appear wildly paradoxical and subversive. The doctrine in question is this: that it is undesirable to believe a proposition when there is no ground whatever for supposing it true.

He who perceives death perceives a sense of the human comedy, and quickly becomes a poet.

Empire is emerging today as the center that supports the globalization of productive networks and casts its widely inclusive net to try to envelop all power relations within its world order - and yet at the same time it deploys a powerful police function against the new barbarians and the rebellious slaves who threaten its order.

Fourth, this supreme law, which is celestial and living harmony, does not so much as demand that the special ideas shall surrender their peculiar arbitrariness and caprice entirely; for that would be self-destructive. It only requires that they influence and be influenced by one another.

So clearly will truths kindle light for truths.

Its first ethical precept is the identity of means used and aims sought. The ultimate end of all revolutionary social change is to establish the sanctity of human life, the dignity of man, the right of every human being to liberty and wellbeing. Unless this be the essential aim of revolution, violent social changes would have no justification. For external social alterations can be, and have been, accomplished by the normal processes of evolution. Revolution, on the contrary, signifies not mere external change, but internal, basic, fundamental change. That internal change of concepts and ideas, permeating ever-larger social strata, finally culminates in the violent upheaval known as revolution.
