It seemed clear to me that life and the world somehow depended upon me now. I may almost say that the world now seemed created for me alone: if I shot myself the world would cease to be at least for me. I say nothing of its being likely that nothing will exist for anyone when I am gone, and that as soon as my consciousness is extinguished the whole world will vanish too and become void like a phantom, as a mere appurtenance of my consciousness, for possibly all this world and all these people are only me myself.

Kings will be tyrants from policy, when subjects are rebels from principle.

What then did you expect when you unbound the gag that muted those black mouths? That they would chant your praises? Did you think that when those heads that our fathers had forcibly bowed down to the ground were raised again, you would find adoration in their eyes?

It is a paralogism to say, that the good of the individual should give way to that of the public; this can never take place, except when the government of the community, or, in other words, the liberty of the subject is concerned; this does not affect such cases as relate to private property, because the public good consists in everyone's having his property, which was given him by the civil laws, invariably preserved.

The infliction of cruelty with a good conscience is a delight to moralists. That is why they invented Hell.

Logic chases truth up the tree of grammar.

To reckon on anything at all, here or elsewhere, is to afford proofs that we are still burdened with chains. The reprobate aspires to paradise; this aspiration disparages, compromises him. To be free is to rid yourself forever of the notion of reward, it is to expect nothing of men or gods, it is to renounce not only this world and all worlds but salvation itself-it is to destroy even the notion of it, that chain among chains.

We reason deeply, when we forcibly feel.

Hegel's philosophy revolved about the universality of reason; it was a rational system with its every part (the subjective as well as the objective spheres) integrated into a comprehensive whole. Marx shows that capitalist society first put such a universality into practice.

Defined from outside and quite empirically, complete civilization consists in realizing all possible progress in discovery and invention and in the arrangements of human society, and seeing that they work together for the spiritual perfecting of individuals, which is the real and final object of civilization. Reverence for life is in a position to complete this conception of civilization and to build its foundations on what lies at the core of our being. This it does by defining what is meant by the spiritual perfecting of man and making it consist in reaching the spirituality of an ever-deepening reverence for life.

Of what I am, I know no more than that I am, but here no tie is necessary between subject and object. My own being is this tie, I am at once the subject knowing, and the object known of; and this reflection or return of the knowledge on itself is what I designate by the term I, if I have any determinate meaning.

Men exist for the sake of one another. Teach them then or bear with them.

It is the quality of a great soul to scorn great things and to prefer that which is ordinary rather than that which is too great.

Men are eager to tread underfoot what they have once too much feared.

No one has yet added up all the heavy, stress-filled workdays as well as the hundreds, perhaps thousands, of lives that are wasted to produce the world's amusements. It is for this reason that "amusements" are not so amusing.

The Palaetiological Sciences point backwards with lines which are broken, but which all converge to the 'same' invisible point: and this point is the Origin of the Moral and Spiritual, as well as of the natural world.

M. Desargues puts me under obligations on account of the pains that it has pleased him to have in me, in that he shows that he is sorry that I do not wish to study more in geometry, but I have resolved to quit only abstract geometry, that is to say, the consideration of questions which serve only to exercise the mind, and this, in order to study another kind of geometry, which has for its object the explanation of the phenomena of nature... You know that all my physics is nothing else than geometry.

Adam came from great power and great wealth, but he was not worthy of you. For had he been worthy, [he would] not [have tasted] death.

If, then, a phenomenon admits of a complete mechanical explanation, it will admit of an infinity of others, that will render an account equally well of all the particulars revealed by experiment.

Many people think they are thinking when they are merely rearranging their prejudices. 

Nature has placed mankind under the governance of two sovereign masters, pain and pleasure. It is for them alone to point out what we ought to do, as well as to determine what we shall do. On the one hand the standard of right and wrong, on the other the chain of causes and effects, are fastened to their throne. They govern us in all we do, in all we say, in all we think: every effort we can make to throw off our subjection, will serve but to demonstrate and confirm it. In words a man may pretend to abjure their empire: but in reality he will remain subject to it all the while. The principle of utility recognizes this subjection, and assumes it for the foundation of that system, the object of which is to rear the fabric of felicity by the hands of reason and of law. Systems which attempt to question it, deal in sounds instead of sense, in caprice instead of reason, in darkness instead of light.

I believe in clear-cut positions. I think that the most arrogant position is this apparent, multidisciplinary modesty of "what I am saying now is not unconditional, it is just a hypothesis," and so on. It really is a most arrogant position. I think that the only way to be honest and expose yourself to criticism is to state clearly and dogmatically where you are. You must take the risk and have a position.

It seems as if the female spirit of the world were mourning everlastingly over blessings, not lost, but which she has never had, and which, in her discouragement she feels that she never will have, they are so far off.

Among the foundations of the Higher Mathematics is also the 'Idea of a Limit'. The Idea of a Limit cannot be superseded by any other definitions or Hypotheses.

I came to set fire to the earth, and I wish it were already on fire!

The appearance in nineteenth-century psychiatry, jurisprudence, and literature of a whole series of discourses on the species and subspecies of homosexuality, inversion, pederasty, and "psychic hermaphroditism" made possible a strong advance of social controls into this area of "perversity"; but it also made possible the formation of a "reverse" discourse: homosexuality began to speak in its own behalf, to demand that its legitimacy or "naturality" be acknowledged, often in the same vocabulary, using the same categories by which it was medically disqualified.

For a long time - always, in fact - I have known that life here on earth is not what I needed and that I wasn't able to deal with it; for this reason and for this reason alone, I have acquired a touch of spiritual pride, so that my existence seems to me the degradation and the erosion of a psalm.

Alas! in the clothes of the greatest potentate, what is there but a man?

Interest only becomes one-sided and morbid only when it ceases to be frank, and becomes sly and furtive.

I must interpret the life about me as I interpret the life that is my own. My life is full of meaning to me. The life around me must be full of significance to itself. If I am to expect others to respect my life, then I must respect the other life I see, however strange it may be to mine. And not only other human life, but all kinds of life: life above mine, if there be such life; life below mine, as I know it to exist. Ethics in our Western world has hitherto been largely limited to the relations of man to man. But that is a limited ethics. We need a boundless ethics which will include the animals also.

The gradual spread of sterility in seeding plants would result in a global catastrophe that could eventually wipe out higher life forms, including humans, from the planet.

War prosperity is like the prosperity that an earthquake or a plague brings.

For a good cause, wrongdoing is virtuous.

A man who has never been within the tropics does not know what a thunderstorm means; a man who has never looked on Niagara has but a faint idea of a cataract; and he who has not read Barère's Memoirs may be said not to know what it is to lie.

There are two types of poor people, those who are poor together and those who are poor alone. The first are the true poor, the others are rich people out of luck.

Force overcome by force.

The criticism of religion ends with the doctrine that man is the supreme being for man, hence the categorical imperative to overthrow all those conditions in which man is degraded, enslaved, neglected, contemptible being-conditions which can hardly be better described than in the exclamation of a Frenchman on the occasion of a proposed tax upon dogs: 'Wretched dogs! They want to treat you like men!'

If we could sleep twenty-four hours a day, we would soon return to the primordial slime, the beatitude of that perfect torpor before Genesis-the dream of every consciousness sick of itself.

But like the desire for eternal life, the desire for omniscience and absolute perfection is merely an imaginary desire; and, as history and daily experience prove, the supposed human striving for unlimited knowledge and perfection is a myth. Man has no desire to know everything; he only wants to know the things to which he is particularly drawn.

An irrational fear should never be simply let alone, but should be gradually overcome by familiarity with its fainter forms.

To discover the various use of things is the work of history.

The Vedas contain a sensible account of God." "The veneration in which the Vedas are held is itself a remarkable feat. Their code embraced the whole moral life of the Hindus and in such a case there is no other truth than sincerity. Truth is such by reference to the heart of man within, not to any standard without.

The materialists say, it is by means of a series of straight lines more or less perfect that one imagines the perfect straight line as an ideal limit. That is right, but the progression in itself necessarily contains what is infinite; it is in relation to the perfect straight line that one can say that such and such a straight line is less twisted than some other. ... Either one conceives the infinite or one does not conceive at all.

Victories over ingrained patterns of thought are not won in a day or a year.

All the opinions of the world agree in this, that pleasure is our end.
