Morality is not properly the doctrine of how we may make ourselves happy, but how we may make ourselves worthy of happiness.

Men sometimes submit to shame, to tyranny, to conquest, but they never long suffer anarchy. There is no people so barbarous that they escape this general law of humanity.

II. The tax which each individual is bound to pay ought to be certain, and not arbitrary.

The industrial peak of a people when its main concern is not yet gain, but rather to gain.

Everyone who is seriously involved in the pursuit of science becomes convinced that some spirit is manifest in the laws of the universe, one that is vastly superior to that of man.

Even the most insensitive hit song enthusiast cannot always escape the feeling that the child with a sweet tooth comes to know in the candy store.

Now any dogma, based primarily on faith and emotionalism, is a dangerous weapon to use on others, since it is almost impossible to guarantee that the weapon will never be turned on the user.

Frenchmen, it was to the noise of hellish songs, the blasphemy of atheism, the cries of death, and the prolonged moans of slaughtered innocence, it was by the light of flames, on the debris of throne and altar, watered by the blood of the best of kings and an innumerable host of other victims, it was by the contempt of morality and the established faith, it was in the midst of every crime that your seducers and your tyrants founded what they call your liberty.

By doing nothing men learn to do ill.

Children and fools speak the truth; and somehow they find happiness in their sincerity.

Those who have racked their brains to discover new proofs have perhaps been induced to do so by a compulsion they could not quite explain to themselves. Instead of giving us their new proofs they should have explained to us the motivation that constrained them to search for them.

I think being a woman is like being Irish... Everyone says you're important and nice, but you take second place all the same.

Life is a task to be done. It is a fine thing to say defunctus est; it means that the man has done his task.

The human understanding is unquiet; it cannot stop or rest, and still presses onward, but in vain. Therefore it is that we cannot conceive of any end or limit to the world, but always as of necessity it occurs to us that there is something beyond... But he is no less an unskilled and shallow philosopher who seeks causes of that which is most general, than he who in things subordinate and subaltern omits to do so.

By striving to do the impossible, man has always achieved what is possible. Those who have cautiously done no more than they believed possible have never taken a single step forward.

Faith exalts the human heart, by removing it from the market-place, making it sacred and unexchangeable. Under the jurisdiction of religion our deeper feelings are sacralized, so as to become raw material for the ethical life: the life lived in judgement.

It takes two to speak the truth, - one to speak, and another to hear.

In the human reality, all existence that spends itself in procuring the prerequisites of existence is thus an "untrue" and unfree existence. Obviously this reflects the not at all ontological condition of a society based on the proposition that freedom is incompatible with the activity of procuring the necessities of life, that this activity is the "natural" function of a specific class, and that cognition of the truth and true existence imply freedom from the entire dimension of such activity. ... Society still is organized in such a way that procuring the necessities of life constitutes the full-time and life-long occupation of specific social classes, which are therefore unfree and prevented from a human existence. In this sense, the classical proposition according to which truth is incompatible with enslavement by socially necessary labor is still valid.

Many conservative writers have contended that the tendency to equality in modern social movements is the expression of envy. In this way they seek to discredit this trend, attributing it to collectively harmful impulses.

It pays to be obvious, especially if you have a reputation for subtlety.

As soon as the generals and the politicos can predict the motions of your mind, lose it. Leave it as a sign to mark the false trail, the way you didn't go. Be like the fox who makes more tracks than necessary, some in the wrong direction. Practice resurrection.

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.

Now he saw the problem with great clarity. If he lived here, life would be pleasant and safe. But it would also be predictable. A child could be born here, grow up here, die here, without ever experiencing the excitement of discovery. Why did Dona question him endlessly about his life in the burrow and his journey to the country of the ants? Because for her, it represented a world that was dangerous and full of fascinating possibilities. For the children of this underground city, life was a matter of repetition, of habit. And this, he suddenly realized, was the heart of the problem. Habit. Habit was a stifling, warm blanket that threatened you with suffocation and lulled the mind into a state of perpetual nagging dissatisfaction. Habit meant the inability to escape from yourself, to change and develop . . .

What the learned world tends to offer is one second-hand scrap of information illustrating ideas derived from another second-hand scrap of information. The second-handedness of the learned world is the secret of its mediocrity.

Life is writing. The sole purpose of mankind is to engrave the thoughts of divinity onto the tablets of nature.

You do not ask what is the value, or what is the use, of this feeling. Of what use is the universe? What is the practical application of a million galaxies? Yet just because it has no use, it has a use-which may sound like a paradox, but is not. What, for instance, is the use of playing music? If you play to make money, to outdo some other artist, to be a person of culture, or to improve your mind, you are not really playing-for your mind is not on the music. You don't swing. When you come to think of it, playing or listening to music is a pure luxury, an addiction, a waste of valuable time and money for nothing more than making elaborate patterns of sound.

Truth is the cry of all, but the game of the few.

Consider that we shouldn't call our brother a fool, since we don't know ourselves what we are.

That one hundred and fifty lawyers should do business together ought not to be expected.

Truly man is a marvellously vain, diverse, and undulating object. It is hard to found any constant and uniform judgement on him.

The harmony between word and deed in Socrates' life is Dorian... manifested in the courage he showed at Delium. This harmonic accord... distinguishes Socrates from a sophist... [who] can give... fine and beautiful discourses on courage, but is not courageous... [U]nlike the sophist, he can use parrhesia and speak freely because what he says accords... with what he thinks... [which] accords... with what he does.

I always made one prayer to God, a very short one. Here it is: "O Lord, make our enemies quite ridiculous!" God granted it.

As if our birth had at first sundered things, and we had been thrust up through into nature like a wedge, and not till the wound heals and the scar disappears, do we begin to discover where we are, and that nature is one and continuous everywhere.

The ascetic morality is a negative morality. And strictly, what is important for a man is not to die, whether he sins or not.

His imperial muse tosses the creation like a bauble from hand to hand to embody any capricious thought that is uppermost in her mind. The remotest spaces of nature are visited, and the farthest sundered things are brought together by a subtle spiritual connection.

The end cannot justify the means for the simple and obvious reason that the means employed determine the nature of the ends produced.

Do I write out of love to men? No, I write because I want to procure for my thoughts an existence in the world; and, even if I foresaw that these thoughts would deprive you of your rest and your peace, even if I saw the bloodiest wars and the fall of many generations springing up from this seed of thought - I would nevertheless scatter it. Do with it what you will and can, that is your affair and does not trouble me.

Man needed one moral constitution to fit him for his original state; he needs another to fit him for his present state; and he has been, is, and will long continue to be, in process of adaptation. And the belief in human perfectibility merely amounts to the belief that, in virtue of this process, man will eventually become completely suited to his mode of life. Progress, therefore, is not an accident, but a necessity. Instead of civilization being artificial, it is part of nature; all of a piece with the development of the embryo or the unfolding of a flower. The modifications mankind have undergone, and are still undergoing, result from a law underlying the whole organic creation; and provided the human race continues, and the constitution of things remains the same, those modifications must end in completeness.

Young man, there is America - which at this day serves for little more than to amuse you with stories of savage men and uncouth manners; yet shall, before you taste of death, show itself equal to the whole of that commerce which now attracts the envy of the world.

Cartan developed a general scheme of infinitesimal geometry in which Klein's notions were applied to the tangent plane and not to the n-dimensional manifold M itself. On the foundations of general infinitesimal geometry.

The world is the totality of facts, not things.

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.

We are not born free, nor do we come into this world with a self-identity and autonomy of our own. We achieve those things, through the conflict and cooperation that weave us into the social fabric.

1. Fidelity & Allegiance sworn to the King is only such a fidelity and obedience as is due to him by the law of the land; for were that faith and allegiance more than what the law requires, we would swear ourselves slaves, and the King absolute; whereas, by the law, we are free men, notwithstanding those Oaths. 2. When, therefore, the obligation by the law to fidelity and allegiance ceases, that by the Oath also ceases...
