By a clock we understand anything characterized by a phenomenon passing periodically through identical phases so that we must assume, by the principle of sufficient reason, that all that happens in a given period is identical with all that happens in an arbitrary period.

I do feel that evolution is being controlled by some sort of divine engineer. I can't help thinking that. And this engineer knows exactly what he or she is doing and why, and where evolution is headed. That's why we've got giraffes and hippopotami and the clap.

After Plotinus, says Schassler, fifteen centuries passed without the slightest scientific interest for the world of beauty and art. ...In reality, nothing of the kind happened. The science of aesthetics ... neither did nor could vanish, because it never existed. ... the Greeks were so little developed that goodness and beauty seemed to coincide. On that obsolete Greek view of life the science of aesthetics was invented by men of the eighteenth century, and especially shaped and mounted in Baumgarten's theory. The Greeks (as anyone may read in Bénard's book on Aristotle and Walter's work on Plato) never had a science of aesthetics.

Man tries to make for himself in the fashion that suits him best a simplified and intelligible picture of the world; he then tries to some extent to substitute this cosmos of his for the world of experience, and thus to overcome it. This is what the painter, the poet, the speculative philosopher, and the natural scientist do, each in his own fashion. Each makes this cosmos and its construction the pivot of his emotional life, in order to find in this way the peace and security which he cannot find in the narrow whirlpool of personal experience.

Down in adoration falling,Lo! the sacred Host we hail;Lo! o'er ancient forms departing,Newer rites of grace prevail;Faith for all defects supplying,Where the feeble senses fail.

Capitalist production, therefore, develops technology, and the combining together of various processes into a social whole, only by sapping the original sources of all wealth - the soil and the labourer.

Imagination is not an empirical or superadded power of consciousness, it is the whole of consciousness as it realizes its freedom.

It is not because the truth is too difficult to see that we make mistakes. It may even lie on the surface; but we make mistakes because the easiest and most comfortable course for us is to seek insight where it accords with our emotions - especially selfish ones.

He was as great as a man can be without morality.

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.

Man in the electronic age has no possible environment except the globe and no possible occupation except information-gathering.

Jazz is the false liquidation of art - instead of utopia becoming reality it disappears from the picture.

We do not count a man's years until he has nothing else to count.

This Burns appeared under every disadvantage: uninstructed, poor, born only to hard manual toil; and writing, when it came to that, in a rustic special dialect, known only to a small province of the country he lived in. Had he written, even what he did write, in the general language of England, I doubt not he had already become universally recognized as being, or capable to be, one of our greatest men.

Democratic socialists are either proletarians who are not yet sufficiently clear about the conditions of the liberation of their class, or they are representatives of the petty bourgeoisie, a class which, prior to the achievement of democracy and the socialist measures to which it gives rise, has many interests in common with the proletariat. It follows that, in moments of action, the communists will have to come to an understanding with these democratic socialists, and in general to follow as far as possible a common policy with them - provided that these socialists do not enter into the service of the ruling bourgeoisie and attack the communists. It is clear that this form of co-operation in action does not exclude the discussion of differences.

A word, once dissected, no longer signifies anything, is nothing. Like a body that, after an autopsy, is less than a corpse.

The end and aim of the Cynic philosophy, as indeed of every philosophy, is happiness, but happiness that consists in living according to nature, and not according to the opinions of the multitude.

It is truly not the merit of the school if we do not come out selfish. Each sort of corresponding pride and every wind of covetousness, eagerness for office, mechanical and servile officiousness, hypocrisy, etc., is bound as much with extensive knowledge as with elegant, classical education, and since this whole instruction exercises no influence of any sort on our ethical behavior, it thus frequently falls to the fate of being forgotten in the same measure as it is not used: one shakes off the dust of the school.

In your actions, don't procrastinate. In your conversations, don't confuse. In your thoughts, don't wander. In your soul, don't be passive or aggressive. In your life, don't be all about business.

My mind is calm, for my fortune is not my felicity. I know I have clean hands and a clean heart, and I hope a clean house for friends or servants; but Job himself, or whoever was the justest judge, by such hunting for matters against him as hath been used against me, may for a time seem foul, especially in a time when greatness is the mark and accusation is the game.

Kant was also quite aware that "the urgent need" of reason is both different from and "more than mere quest and desire for knowledge." Hence, the distinguishing of the two faculties, reason and intellect, coincides with a distinction between two altogether different mental activities, thinking and knowing.

What I have given in the second book on the nature and properties of curved lines, and the method of examining them, is, it seems to me, as far beyond the treatment in the ordinary geometry, as the rhetoric of Cicero is beyond the a, b, c of children.

It is the destiny of our race to become united into one great body, thoroughly connected in all its parts, and possessed of similar culture. Nature, and even the passions and vices of Man, have from the beginning tended towards this end. A great part of the way towards it is already passed, and we may surely calculate that it will in time be reached.

I shall within a few days divest myself of the anxieties and the labors with which I have been oppressed, and retire with inexpressible delight to my family, my friends, my farms, and books. There I may indulge at length in that tranquillity and those pursuits from which I have been divorced by the character of the times in which I have lived, and which have forced me into the line of political life under a sense of duty and against a great and constant aversion to it.

When we make ethical judgments, we must go beyond a personal or sectional point of view and take into account the interests of all those affected, unless we have sound ethical grounds for doing otherwise. (...) The essence of the principle of equal consideration of interests is that we give equal weight in our moral deliberations to the like interests of all those affected by our actions. (...) an interest is an interest, whoever's interest it may be.

If there is a state, then necessarily there is domination and consequently slavery. A state without slavery, open or camouflaged, is inconceivable - that is why we are enemies of the state.

It is not possible to run a course aright when the goal itself has not been rightly placed.

How many, once lauded in song, are given over to the forgotten; and how many who sung their praises are clean gone long ago!

Imaginary pains are by far the most real we suffer, since we feel a constant need for them and invent them because there is no way of doing without them.

The pathos of it all is that the America which is to be protected by a huge military force is not the America of the people, but that of the privileged class; the class which robs and exploits the masses, and controls their lives from the cradle to the grave. No less pathetic is it that so few people realize that preparedness never leads to peace, but that it is indeed the road to universal slaughter.

That a man be willing, when others are so too, as farre-forth, as for Peace, and defence of himself he shall think it necessary, to lay down this right to all things; and be contented with so much liberty against other men, as he would allow other men against himself.

The only medicine for suffering, crime, and all the other woes of mankind, is wisdom.

I call a sign which stands for something merely because it resembles it, an icon. Icons are so completely substituted for their objects as hardly to be distinguished from them. Such are the diagrams of geometry. A diagram, indeed, so far as it has a general signification, is not a pure icon; but in the middle part of our reasonings we forget that abstractness in great measure, and the diagram is for us the very thing. So in contemplating a painting, there is a moment when we lose the consciousness that it is not the thing, the distinction of the real and the copy disappears, and it is for the moment a pure dream, - not any particular existence, and yet not general. At that moment we are contemplating an icon.

She [virtue] requires a rough and stormy passage; she will have either outward difficulties to wrestle with, ... or internal difficulties.

Look within. Within is the fountain of the good, and it will ever bubble up, if thou wilt ever dig.

The Methods of Observation of Quantity in general, are 'Numeration', which is precise by the nature of Number; the 'Measurement of Space' and 'of Time', which are easily made precise; the 'Conversion of Space and Time', by which each aids the measurement of the other. The Idea of Space becomes more clear by studying 'Geometry'; the Idea of Force, by studying 'Mechanics'; the Ideas of Likeness, of Kind, of subordination of Classes, by studying 'Natural History'.

Always remember that it is impossible to speak in such a way that you cannot be misunderstood: there will always be some who misunderstand you.

There can be no liberty for a community which lacks the information by which to detect lies.

If I knew of something that could serve my nation but would ruin another, I would not propose it to my prince, for I am first a man and only then a Frenchman, because I am necessarily a man, and only accidentally am I French.

Jesus, in some respects, was an anarchist, for he had no idea of civil government. That government seems to him purely and simply an abuse.

Can the "word" be pinned down to either one period or one church? All churches are, of course, only more or less unsuccessful attempts to represent the unseen to the mind.

Whatever you can lose, you should reckon of no account.

We know very well that we are only allowed to go on eating our dinner, to finish seeing the new play, or to enjoy to the end the ball, the Christmas fete, the promenade, the races or, the hunt, thanks to the policeman's revolver or the soldier's rifle, which will shoot down the famished outcast who has been robbed of his share, and who looks round the corner with covetous eyes at our pleasures, ready to interrupt them instantly, were not policeman and soldier there prepared to run up at our first call for help.

Every nation gets the government it deserves.

For on these matters we should not trust the multitude who say that none ought to be educated but the free, but rather to philosophers, who say that the educated alone are free.

With respect to a true culture and manhood, we are essentially provincial still, not metropolitan, - mere Jonathans. We are provincial, because we do not find at home our standards, - because we do not worship truth, but the reflection of truth, - because we are warped and narrowed by an exclusive devotion to trade and commerce and manufactures and agriculture and the like, which are but means, and not the end.

When I speak of 'negative dialectics' not the least important reason for doing so is my desire to dissociate myself from this fetishization of the positive.

For such is the nature of men, that howsoever they may acknowledge many others to be more witty, or more eloquent, or more learned; Yet they will hardly believe there be many so wise as themselves: For they see their own wit at hand, and other men's at a distance.
