And now I have explained the series of social and intellectual conditions by which the discovery of sociological laws, and consequently the foundation of Positivism, was fixed for the precise date at which I began my philosophical career: that is to say, one generation after the progressive dictatorship of the Convention, and almost immediately after the fall of the retrograde tyranny of Bonaparte.

The Heavenly City outshines Rome, beyond comparison. There, instead of victory, is truth; instead of high rank, holiness; instead of peace, felicity; instead of life, eternity.

A civilization is a social entity that manifests religious, political , legal, and customary uniformity over an extended period, and which confers on its members the benefits of socially accumulated knowledge.

The principles of ethics come from our own nature as social, reasoning beings.

Economic man deals with the "real world" in all its complexity. Administrative man recognizes that the world he perceives is a drastic simplified model... He makes his choices using a simple picture of the situation that takes into account just a few of the factors that he regards as most relevant and crucial.

I have twice gone fishing with rod and line just because other boys asked me to, but this sport was soon made impossible for me by the treatment of the worms that were put on the hook for bait, and the wrenching of the mouths of the fishes that were caught. I gave it up, and even found courage enough to dissuade other boys from going.

I am a lover of liberty. I will not and I cannot serve a party.

Emptiness is not a denial of the proper but an affirmation of it.

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

Most of the luxuries, and many of the so-called comforts of life, are not only not indispensable, but positive hindrances to the elevation of mankind.

There is no more important rule of conduct in the world than this: attach yourself as much as you can to people who are abler than you and yet not so very different that you cannot understand them.

Some propose mere welfare measures - while others come forward with grandiose systems of reform which, under the pretense of re-organizing society, are in fact intended to preserve the foundations, and hence the life, of existing society. Communists must unremittingly struggle against these bourgeois socialists because they work for the enemies of communists and protect the society which communists aim to overthrow.

Aims, principles, &c., have a place in our thoughts, in our subjective design only; but not yet in the sphere of reality. That which exists for itself only, is a possibility, a potentiality; but has not yet emerged into Existence. A second element must be introduced in order to produce actuality - viz. actuation, realization; and whose motive power is the Will - the activity of man in the widest sense.

Comrades, I've voyaged long and far on sea and soul,my eyes have seen disease, gods, ghosts, and men, and yetin no land have I seen a more false, murderous sirenthan that wind-headed, babbling, blind bitch-hound called Hope!

Socrates did not stop with a philosophical consideration of mankind; he addressed himself to each one individually, wrested everything from him, and sent him away empty-handed.

At dawn, when you have trouble getting out of bed, tell yourself: 'I have to go to work - as a human being. What do I have to complain of, if I'm going to do what I was born for - the things I was brought into the world to do? Or is this what I was created for? To huddle under the blankets and stay warm?' 

Our age is retrospective. It builds the sepulchres of the fathers. It writes biographies, histories, and criticism. The foregoing generation beheld God and nature face to face; we, through their eyes. Why should not we also enjoy an original relation to the universe. Why should not we have a poetry and philosophy of insight and not of tradition, and a religion by revelation to us, and not the history of theirs?

books are only what we want them to be; rather, what we read into them.

Jesus is too colossal for the pen of phrasemongers, however artful. No man can dispose of Christianity with a bon mot.

It is indeed a matter of great difficulty to discover, and effectually to distinguish, the true motions of particular bodies from the apparent; because the parts of that immovable space, in which those motions are performed, do by no means come under the observation of our senses. Yet the thing is not altogether desperate; for we have some arguments to guide us, partly from the apparent motions, which are the differences of the true motions; partly from the forces, which are the causes and effects of the true motions.

Philosophy is an everlasting fire, sometimes damped down by setting itself limits, then flaring into new life as it consumes them. Every field of inquiry is limited, but philosophy has an essential relation to the question of limits, to its own limits.

He was a one-book man. Some men have only one book in them; others, a library.

...and woe betide fateful curiosity should it ever succeed in peering through a crack in the chamber of consciousness, out and down into the depths, and thus gain an intimation of the fact that humanity, in the indifference of its ignorance, rests on the pitiless, the greedy, the insatiable, the murderous clinging in dreams, as it were, to the back of a tiger.

What a monument of human smallness is this idea of the philosopher king. What a contrast between it and the simplicity of humaneness of Socrates, who warned the statesmen against the danger of being dazzled by his own power, excellence, and wisdom, and who tried to teach him what matters most - that we are all frail human beings. What a decline from this world of irony and reason and truthfulness down to Plato's kingdom of the sage whose magical powers raise him high above ordinary men; although not quite high enough to forgo the use of lies, or to neglect the sorry trade of every shaman - the selling of spells, of breeding spells, in exchange for power over his fellow-men.

I am for freedom of religion, & against all maneuvres to bring about a legal ascendancy of one sect over another, for freedom of the press, and against all violations of the Constitution to silence by force and not by reason the complaints or criticisms, just or unjust, of our citizens against the conduct of their agents.

Man is forming thousands of ridiculous relations between himself and God.

In the case of colors, there is a tridimensional spread of feelings. Originally all feelings may have been connected in the same way, and the presumption is that the number of dimensions was endless. For development essentially involves a limitation of possibilities. But given a number of dimensions of feeling, all possible varieties are obtainable by varying the intensities of the different elements.

The correct relationship between the higher and lower classes, the appropriate mutual interaction between the two is, as such, the true underlying support on which the improvement of the human species rests. The higher classes constitute the mind of the single large whole of humanity; the lower classes constitute its limbs; the former are the thinking and designing part, the latter the executive part.

Eros conquers depression.

A living dog is better than a dead lion. Shall a man go and hang himself because he belongs to the race of pygmies, and not be the biggest pygmy that he can? Let every one mind his own business, and endeavor to be what he was made. Why should we be in such desperate haste to succeed, and in such desperate enterprises? If a man does not keep pace with his companions, perhaps it is because he hears a different drummer. Let him step to the music which he hears, however measured or far away.

...no legislator, at any period of the world, has willingly placed the seat of active power in the hands of the multitude: Because there it admits of no control, no regulation; no steady direction whatsoever. The people are the natural control on authority; but to exercise and to control together is contradictory and impossible.

Hype is the awkward and desperate attempt to convince journalists that what you've made is worth the misery of having to review it.

The salvation of reality is its obstinate, irreducible, matter-of-fact entities, which are limited to be no other than themselves. Neither science, nor art, nor creative action can tear itself away from obstinate, irreducible, limited facts.

Live among men as if God beheld you; speak with God as if men were listening.

Bishop Berkeley destroyed this world in one volume octavo; and nothing remained after his time, but mind - which experienced a similar fate from the hand of Mr. Hume, in 1737.

An appeal to his alarm is never a good plan to rid oneself of a spirited young man.

Everything is the work of imagination, and... all the faculties of the soul can be correctly reduced to pure imagination...

Modern man may assert that he can dispense with them, and he may bolster his opinion by insisting that there is no scientific evidence of their truth. But since we are dealing with invisible and unknowable things (for God is beyond human understanding, and there is no mean of proving immortality), why should we bother with evidence?

I entirely agree with you, as to the ill tendency of the affected doubts of some philosophers, and fantastical conceit of others. I am even so far gone of late in this way of think, that I have quitted several of the sublime notions I had got in their schools for vulgar opinions. And I give it you on my word, since this revolt from metaphysical notions to the plain dictates of nature and common sense, I find my understanding strangely enlightened, so that I can now easily comprehend a great many thing which before were all mystery and riddle.
