We know nothing accurately in reality, but only as it changes according to the bodily condition, and the constitution of those things that flow upon the body and impinge upon it.

The moral decline we are compelled to witness and the suffering it engenders are so oppressive that one cannot ignore them even for a moment. No matter how deeply one immerses oneself in work, a haunting feeling of inescapable tragedy persists. Still, there are moments when one feels free from one's own identification with human limitations and inadequacies. At such moments, one imagines that one stands on some spot of a small planet, gazing in amazement at the cold yet profoundly moving beauty of the eternal, the unfathomable: life and death flow into one, and there is neither evolution nor destiny; only being.

Emptiness simply prevents what is individual from insisting on itself.

And the conversion of the other Don Quixote - he who was converted only to die - was possible because he was mad, and it was his madness, and not his death or his conversion that immortalized him, earning him forgiveness for this crime of having been born. Felix culpa! And neither was his madness cured, but only transformed. His death was his last knightly adventure; in dying he stormed heaven, which suffereth violence.

He who would write heroic poems should make his whole life a heroic poem.

If we admit the existence of the prophetic mission, by putting the idea of possibility, which is in fact ignorance, in place of certainty, and make miracles a proof of the truth of man who claims to be a prophet it becomes necessary that they should not be used by a person, who says that they can be performed by others than prophets, as the Mutakallimun do.

Nothing is hidden so much that it wouldn't be revealed through its fruit.

It appears... that a work similar in its object and general conception to that of Adam Smith, but adapted to the more extended knowledge and improved ideas of the present age, is the kind of contribution which Political Economy at present requires. The Wealth of Nations is in many parts obsolete, and in all, imperfect. Political Economy... has grown up almost from infancy since the time of Adam Smith; and the philosophy of society... has advanced many steps beyond the point at which he left it.

Wisdom, if it were young, would cherish love, nursing it with devotion, deepening it with sacrifice, vitalizing with parentage, making all things subordinate to it till the end. Even though it consumes us in its service and overwhelms us with tragedy, even though it breaks us down with separations, let it be first. How can it matter what price we pay for love?

You rejoice in having made a convert to Atheism. I think there is something unnatural in a zeal of proselytism in an Atheist. I do not believe in an intellectual God, a God made after the image of man. In the vulgar acceptation of the word, therefore, I think a man is right who does not believe in God, but I am also persuaded that a man is wrong who is without religion.

Those who read and rightly understand my teaching will not start an insurrection; they have not learned that from me.

Reason alone does not suffice.

He knows his own strength; he knows that he was born to carry burdens.

What, in unenlightened societies, colour, race, religion, or in the case of a conquered country, nationality, are to some men, sex is to all women; a peremptory exclusion from almost all honourable occupations, but either such as cannot be fulfilled by others, or such as those others do not think worthy of their acceptance.

Serious reflexion about one's own character will often induce a curious sense of emptiness; and if one knows another person well, one may sometimes intuit a similar void in him. (This is one of the strange privileges of friendship.)

Earnest in practicing the ordinary virtues, and careful in speaking about them, if, in his practice, he has anything defective, the superior man dares not but exert himself; and if, in his words, he has any excess, he dares not allow himself such license. Thus his words have respect to his actions, and his actions have respect to his words; is it not just an entire sincerity which marks the superior man?

Bourgeois class domination is undoubtedly an historical necessity, but, so too, the rising of the working class against it. Capital is an historical necessity, but, so too, its grave digger, the socialist proletariat.

The Union was a measure from which infinite Good has been derived to this country.

What was man before the invention of words and the knowledge of language? An animal..

I think he once told us his first short clothes were a hull made mostly or wholly of leather. We all only laughed, for it is now long ago. Thou dear father! Through what stern obstructions was thy way to manhood to be forced, and for us and for our travelling to be made smooth!

Wouldn't it be as farfetched to call birth the cause of death as to call the cat's head the cause of the tail? Lifting the neck of a bottle implies lifting the bottom as well, for the "two parts" come up at the same time. If I pick up an accordion by one end, the other will follow a little later, but the principle is the same. Total situations are, therefore, patterns in time as much as patterns in space.

There is no man so good, who, were he to submit all his thoughts and actions to the laws, would not deserve hanging ten times in his life.

The standard that I always come back to is the health of the world, which is the same as our own personal health. We can't distinguish our health from the health of everything else. And we know enough from the ecologists now to know that health is a very complex and un-understandable complexity of relationships that makes the world whole.

To be without some of the things you want is an indispensable part of happiness.

When we know what words are worth, the amazing thing is that we try to say anything at all, and that we manage to do so. This requires, it is true, a supernatural nerve.

Suppose that I wish to deserve the title of "robber of remorse" and that I place in myself all the townspeople's repentence?

I find it wholesome to be alone the greater part of the time. To be in company, even with the best, is soon wearisome and dissipating. I love to be alone. I never found the companion that was so companionable as solitude. We are for the most part more lonely when we go abroad among men than when we stay in our chambers. A man thinking or working is always alone, let him be where he will... The really diligent student... is as solitary as a dervish in the desert. The farmer can work alone in the field or the woods all day, hoeing or chopping, and not feel lonesome.

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.

The only thing the young should be taught is that there is virtually nothing to be hoped for from life. One dreams of a Catalogue of Disappointments which would include all the disillusionments reserved for each and every one of us, to be posted in the schools.

Our profound human duty is not to interpret or to cast light on the rhythm of God's arch, but to adjust, as much as we can, the rhythm of our small and fleeting life to his. Only thus may we mortals succeed in achieving something immortal, because then we collaborate with One who is Deathless. Only thus may we conquer mortal sin, the concentration on details, the narrowness of our brains; only thus may we transubstantiate into freedom the slavery of earthen matter given us to mold.

The defiance of established authority, religious and secular, social and political, as a world-wide phenomenon may well one day be accounted the outstanding event of the last decade.

When national debts have once been accumulated to a certain degree, there is scarce, I believe, a single instance of their having been fairly and completely paid. The liberation of the public revenue, if it has ever been brought about at all, has always been brought about by bankruptcy; sometimes by an avowed one, but always by a real one, though frequently by a pretend payment.

Too busy with the crowded hour to fear to live or die.

Scientific men get an awkward habit - no, I won't call it that, for it is a valuable habit - of believing nothing unless there is evidence for it; and they have a way of looking upon belief which is not based upon evidence, not only as illogical, but as immoral.

In our contemporary social and intellectual plight, it is nothing less than shocking to discover that those persons who claim to have discovered an absolute are usually the same people who also pretend to be superior to the rest. To find people in our day attempting to pass off to the world and recommending to others some nostrum of the absolute which they claim to have discovered is merely a sign of the loss of and the need for intellectual and moral certainty, felt by broad sections of the population who are unable to look life in the face.

The mind must be indulged, and leisure must be given from time to time, which is the place of food and strength.

The move from a structuralist account in which capital is understood to structure social relations in relatively homologous ways to a view of hegemony in which power relations are subject to repetition, convergence, and rearticulation brought the question of temporality into the thinking of structure, and marked a shift from a form of Althusserian theory that takes structural totalities as theoretical objects to one in which the insights into the contingent possibility of structure inaugurate a renewed conception of hegemony as bound up with the contingent sites and strategies of the rearticulation of power.

The proper method for hastening the decay of error is not by brute force, or by regulation which is one of the classes of force, to endeavour to reduce men to intellectual uniformity; but on the contrary by teaching every man to think for himself.

First we have to believe, and then we believe.

Criticism alone can sever the root of materialism, fatalism, atheism, free-thinking, fanaticism, and superstition, which can be injurious universally; as well as of idealism and skepticism, which are dangerous chiefly to the Schools, and hardly allow of being handed on to the public.

Ignorance is not a simple lack of knowledge but an active aversion to knowledge, the refusal to know, issuing from cowardice, pride or laziness of mind. 

You have theories enough concerning the Rights of Men. It may not be amiss to add a small degree of attention to their Nature and disposition.
