By convention sweet is sweet, bitter is bitter, hot is hot, cold is cold, color is color; but in truth there are only atoms and the void.

Thus, all unknown quantities can be expressed in terms of a single quantity, whenever the problem can be constructed by means of circles and straight lines, or by conic sections, or even by some other curve of degree not greater than the third or fourth.But I shall not stop to explain this in more detail, because I should deprive you of the pleasure of mastering it yourself, as well as of the advantage of training your mind by working over it, which is in my opinion the principal benefit to be derived from this science. Because, I find nothing here so difficult that it cannot be worked out by anyone at all familiar with ordinary geometry and with algebra, who will consider carefully all that is set forth in this treatise.

A strong memory is commonly coupled with infirm judgment.

It is the same: a chosen one is a man whom God's finger crushes against the wall.

If people were told: what makes carnal desire imperious in you is not its pure carnal element. It is the fact that you put into it the essential part of yourself-the need for Unity, the need for God - they wouldn't believe it. To them it seems obvious that the quality of imperious need belongs to the carnal desire as such. In the same way it seems obvious to the miser that the quality of desirability belongs to gold as such, and not to its exchange value.

Someone who knows too much finds it hard not to lie.

It is always necessary that the substance or essence of a person be good before there can be any good works and that good works follow and proceed from a person who is already good. Christ says in Matthew 7:18: "A good tree cannot bear bad fruit, nor can a bad tree bear good fruit." ... The fruit does not make the tree good or bad but the tree itself is what determines the nature of the fruit. In the same way, a person first must be good or bad before doing a good or bad work.

But what of the poor Ghosts who never get into the omnibus at all?' 'Everyone who wishes it does. Never fear. There are only two kinds of people in the end: those who say to God, "Thy will be done," and those to whom God says, in the end, "Thy will be done." All that are in Hell, choose it. Without that self-choice there could be no Hell. No soul that seriously and constantly desires joy will ever miss it. Those who seek find. To those who knock it is opened.

Several particular maxims... are as powerful, although false, in carrying away belief, as those the most true.

The good life is one inspired by love and guided by knowledge.

When we have chosen the vocation in which we can contribute most to humanity, burdens cannot bend us because they are only sacrifices for all. Then we experience no meager, limited, egotistic joy, but our happiness belongs to millions, our deeds live on quietly but eternally effective, and glowing tears of noble men will fall on our ashes.

Astronomy is perhaps the science whose discoveries owe least to chance, in which human understanding appears in its whole magnitude, and through which man can best learn how small he is.

The sentiment that dominates all Rousseau's works is a certain plebeian anger that excites him against every kind of superiority. The energetic submission of the wise man bends nobly under the indispensable empire of social distinctions, and never does be appear greater than when he bows; but Rousseau has nothing at all of this loftiness. Weak and surly, he spent his life spouting insults to the great, as he would have offered the same to the people if he had been born a great lord.

The disastrous feature of our civilization is that it is far more developed materially than spiritually. Its balance is disturbed ... Now come the facts to summon us to reflect. They tell us in terribly harsh language that a civilization which develops only on its material side, and not in the sphere of the spirit ... heads for disaster.

I recognize the necessity of animal experiments with my mind but not with my heart.

Those who devote themselves to rituals must ignore themselves. Rituals produce a distance from the self, a self-transcendence.

Do not mistake yourself by believing that your being has something in it more exalted than that of others.

If you get the message, hang up the phone. For psychedelic drugs are simply instruments, like microscopes, telescopes, and telephones. The biologist does not sit with eye permanently glued to the microscope, he goes away and works on what he has seen.

To have faith is to trust yourself to the water. When you swim you don't grab hold of the water, because if you do you will sink and drown. Instead you relax, and float.

He who feared that he would not succeed sat still.

Free in this world as the birds in the air, disengaged from every kind of chains, those who have practiced the Yoga gather in Brahmin the certain fruit of their works. Depend upon it; rude and careless as I am, I would fain practice the yoga faithfully. This Yogi, absorbed in contemplation, contributes in his degree to creation; he breathes a divine perfume, he heard wonderful things. Divine forms traverse him without tearing him and he goes, he acts as animating original matter. To some extent, and at rare intervals, even I am a Yogi.

It may be expedient but it is not just that some should have less in order that others may prosper.

Zeno: The many do not know that except by this devious passage through all things the mind cannot attain to the truth. Zeno: Most people are not aware that this roundabout progress through all things is the only way in which the mind can attain truth and wisdom.

Music must take rank as the highest of the fine arts - as the one which, more than any other, ministers to human welfare.

The great and inspiring aims of the Revolution became so clouded with and obscured by the methods used by the ruling political power that it was hard to distinguish what was temporary means and what final purpose. Psychologically and socially the means necessarily influence and alter the aims. The whole history of man is continuous proof of the maxim that to divest one's methods of ethical concepts means to sink into the depths of utter demoralization. In that lies the real tragedy of the Bolshevik philosophy as applied to the Russian Revolution. May this lesson not be in vain.

And thus Christianity is played in, Christendom. Artists in dramatic costumes make their appearance in artistic buildings-there really is no danger at all, anything but that: the teacher is a royal functionary, steadily promoted, making a career-and how he dramatically plays Christianity, in short, he plays comedy. He lectures about renunciation, but he himself is being steadily promoted; he teaches all that about despising worldly titles and rank, but he himself is making a career.

Tis a good word and a profitable desire, but withal absurd; for to make the handle bigger than the hand, the cubic longer than the arm, and to hope to stride further than our legs can reach, is both impossible and monstrous; or that man should rise above himself and humanity; for he cannot see but with his eyes, nor seize but with his hold. He shall be exalted, if God will lend him an extraordinary hand; he shall exalt himself, by abandoning and renouncing his own proper means, and by suffering himself to be raised and elevated by means purely celestial. It belongs to our Christian faith, and not to the stoical virtue, to pretend to that divine and miraculous metamorphosis.

There can be no safer deposit on earth than the Treasury of the United States.

Technologies themselves, regardless of content, produce a hemispheric bias in the users.

As these people are not convicted of forfeiting freedom, they have still a natural, perfect right to it; and the Governments whenever they come should, in justice set them free, and punish those who hold them in slavery.

Within the last half century, the labours of such men as Von Baer, Rathke, Reichert, Bischof, and Remak, have almost completely unravelled... the successive stages of development which... are now as well known to the embryologist as are the steps of the metamorphosis of the silk-worm moth to the school boy.

The different pieces of evidence did not constitute so many neutral elements, until such time as they could be gathered together into a single body of evidence that would bring the final certainty of guilt. Each piece of evidence aroused a particular degree of abomination. Guilt did not begin when all the evidence was gathered together; piece by piece, it was constituted by each of the elements that made it possible to recognize a guilty person. Thus a semi-proof did not leave the suspect innocent until such time as it was completed; it made him semi-guilty; slight evidence of a serious crime marked someone as slightly criminal. In short, penal demonstration did not obey a dualistic system: true or false; but a principle of continuous gradation; a degree reached in the demonstration already formed a degree of guilt and consequently involved a degree of punishment.

A real man is he whose goodness is a part of himself.

What the inventive genius of mankind has bestowed upon us in the last hundred years could have made human life care free and happy if the development of the organizing power of man had been able to keep step with his technical advances. As it is, the hardly bought achievements of the machine age in the hands of our generation are as dangerous as a razor in the hands of a three-year-old child. The possession of wonderful means of production has not brought freedom-only care and hunger.

I have often seen an actor laugh off the stage, but I don't remember ever having seen one weep.

Can one be a saint without God?, that's the problem, in fact the only problem, I'm up against today.

As the mathematics are now understood, each branch - or, if you please, each problem, - is but the study of the relations of a collection of connected objects, without parts, without any distinctive characters, except their names or designating letters. These objects are commonly called points; but to remove all notion of space relations, it may be better to name them monads. The relations between these points are mere complications of two different kinds of elementary relations, which may be termed immediate connection and immediate non-connection. All the monads except as serve as intermediaries for the connections have distinctive designations.

The Master said, "He who exercises government by means of his virtue may be compared to the north polar star, which keeps its place and all the stars turn towards it."

If, then, in the sphere of action there is some one end which we desire for its own sake, and for the sake of which we desire every thing else; and if we do not choose every thing for the sake of something else, for this would go on without limit, and our desire would be idle and futile, it is clear that this must be the supreme good, and the best thing of all.

I am enraptured by Hindu philosophy, whose essential endeavor is to surmount the self; and everything I do, everything I think is only myself and the selfs humiliations.

Emptiness simply prevents what is individual from insisting on itself.

Blot out vain pomp; check impulse; quench appetite; keep reason under its own control.

Literature is the Thought of thinking Souls.

Everything ideal has a natural basis and everything natural an ideal development.

If a work of art is to explore new environments, it is not to be regarded as a blueprint but rather as a form of action-painting.

This "knowing what to do"... is a matter of having the right purpose, the purpose appropriate to the situation in hand... The one who "knows what to do" is the one on whom you can rely to make the best shot at success, whenever success is possible.

Nostalgia, more than anything, gives us the shudder of our own imperfection.
