Nothing can be of more importance than to separate prejudice and mistake on the one hand from reason and demonstration on the other.

Mr. Sensible learned only catchwords from them. He could talk like Epicurus of spare diet, but he was a glutton. He had from Montaigne the language of friendship, but no friend.

If a lion could talk, we could not understand him.

It is understandable then that tragic heroes, unlike the baroque characters who had preceded them, could never be mad, and that inversely madness could never take on the tragic value we have known since Nietzsche and Artaud. In the classical epoch, tragic characters and the mad face each other without any possible dialogue or common language, for the one can only pronounce the decisive language of being, where the truth of light and the depths of night meet in a flash, and the other repeats endlessly an indifferent murmur where the empty chatter of the day is cancelled out by the deceptive lies of the shadows.

A fool is known by his Speech; and a wise man by Silence.

In the learned professions as in the unlearned, and in human things throughout, in every place and in every time, the true function of intellect is not that of talking, but of understanding and discerning with a view to performing!

Scepticism is the first step towards truth. Variant: A thing is not proved just because no one has ever questioned it. What has never been gone into impartially has never been properly gone into. Hence skepticism is the first step toward truth. It must be applied generally, because it is the touchstone.

If the world were clear, art would not exist.

The whole is a riddle, an aenigma, an inexplicable mystery. Doubt, uncertainty, suspence of judgment appear the only result of our most accurate scrutiny, concerning this subject. But such is the frailty of human reason, and such the irresistible contagion of opinion, that even this deliberate doubt could scarcely be upheld; did we not enlarge our view, and opposing one species of superstition to another, set them a quarrelling; while we ourselves, during their fury and contention, happily make our escape, into the calm, though obscure, regions of philosophy.

The entire lower world was created in the likeness of the higher world. All that exists in the higher world appears like an image in this lower world; yet all this is but One.

Thank you for your letter and for the enclosure which I return herewith. I have been wondering whether there is any means of preventing the confusion between you and me, and I half-thought that we might write a joint letter to The Times in the following terms: Sir, To prevent the continuation of confusions which frequently occur, we beg to state that neither of us is the other. Do you think this would be a good plan?

There stood Mucius, despising the enemy and despising the fire, and watched his hand as it dripped blood over the fire on his enemy's altar, until Porsenna, envying the fame of the hero whose punishment he was advocating, ordered the fire to be removed against the will of the victim.

Whoever complains about the death of anyone, is complaining that he was a man. Everyone is bound by the same terms: he who is privileged to be born, is destined to die.

Then he tried to recall the lessons of Mr. Wisdom. "it is I myself, eternal Spirit, who drives this Me, the slave, along that ledge. I ought not to care whether he falls and breaks his neck or not. It is not he that is real, it is I - I - I.

In my opinion, all things in nature occur mathematically.

I believe that there is a necessary connection in both directions between the physical and the mental, but that it cannot be discovered a priori. Opinion is strongly divided on the credibility of some kind of functionalist reductionism, and I won't go through my reasons for being on the antireductionist side of that debate. Despite significant attempts by a number of philosophers to describe the functional manifestations of conscious mental states, I continue to believe that no purely functionalist characterization of a system entails - simply in virtue of our mental concepts - that the system is conscious.

Poetry is the universal art of the spirit which has become free in itself and which is not tied down for its realization to external sensuous material; instead, it launches out exclusively in the inner space and the inner time of ideas and feelings.

In Lenin I honor a man, who in total sacrifice of his own person has committed his entire energy to realizing social justice. I do not find his methods advisable. One thing is certain, however: men like him are the guardians and renewers [Erneuerer] of mankind's conscience.

No man can have society upon his own terms. If he seeks it, he must serve it too.

The Chinese believe that when there are too many policemen, there can be no individual liberty, when there are too many lawyers, there can be no justice, and when there are too many soldiers, there can be no peace.

It is our deliberate opinion that the French Revolution, in spite of all its crimes and follies, was a great blessing to mankind.

Even where Marx did not soften his main drive to a "revolutionary development," it was still aimed at capitalism alone (a relatively young and derivative cancer) and not equally at the age-old, lasting core of all enslavement, cruelty and exploitation: at militarism, feudalism and the supremacist world at large.

The History of the world is none other than the progress of the consciousness of Freedom; a progress whose development according to the necessity of its nature, it is our business to investigate. 

One naturally regrets not being an expert or one of those insiders who thoroughly understand. It's hell to be an amateur. A little reflection calms your sorrow, however. The experts in their own little speedboat, the rest of us floating with the rest of mankind in a great barge - that is the picture.

One lives but once in the world.

Where the world comes in my way - and it comes in my way everywhere - I consume it to quiet the hunger of my egoism. For me you are nothing but - my food, even as I too am fed upon and turned to use by you. We have only one relation to each other, that of usableness, of utility, of use.

Perhaps misguided moral passion is better than confused indifference.

If there is anyone who owes everything to Bach, it is certainly God.

If a poor person envies a rich person, he is no better than the rich person.

The Pythagoreans made kindness to beasts a training in humanity and pity.

If to describe a misery were as easy to live through it!

Classical science was based upon the belief that it is possible to formulate both the position and velocity at one time of any given particle. It followed that knowledge of the position and velocity of a given number of particles would enable the future behavior of the whole collection to be accurately predicted. The principle of Heisenberg is that given the determination of position, its velocity can be stated only as of a certain order of probability, while if its velocity is determined the correlative factor of position can be stated only as of a certain order of probability. Both cannot be determined at once, from which it follows necessarily that the future of the whole collection cannot possibly be foretold except in terms of some order of probability.

I was still blind, but twinkling stars did dance Throughout my being's limitless expanse, Nothing had yet drawn close, only at distant stages I found myself, a mere suggestion sensed in past and future ages.

Let us ask the Gods not for possessions, but for things to do; happiness is in making things rather than consuming them.

Quite often a man goes on for years imagining that the religious teaching that had been imparted to him since childhood is still intact, while all the time there is not a trace of it left in him.

I shall often go wrong through defect of judgment. When right, I shall often be thought wrong by those whose positions will not command a view of the whole ground. I ask your indulgence for my own errors, which will never be intentional, and your support against the errors of others, who may condemn what they would not if seen in all its parts.

I have often regretted my speech, never my silence.

The divine life that underlies all appearance reveals itself never as a fixed and known entity, but as something that is to be; and after it has become what it was to be, it will reveal itself again to all eternity as something that is to be.

It is the sidereal day, that is, the duration of the rotation of the earth, which is the constant unit of time. ...However ...many astronomers ...think that the tides act as a check on our globe, and that the rotation of the earth is becoming slower and slower. Thus would be explained the apparent acceleration of the motion of the moon...

The greatest events occur without intention playing any part in them; chance makes good mistakes and undoes the most carefully planned undertaking. The world's greatest events are not produced, they happen.

I take toleration to be a part of religion. I do not know which I would sacrifice; I would keep them both: it is not necessary that I should sacrifice either.

On the contrary, to educate rational people, that should be sufficient; it is not really intended for sensible people; to understand things and conditions, there is the matter ended,-to understand oneself does not seem to be everyman's concern.

Behold... the only... rule we can follow: when a phenomenon appears... as the cause of another, we regard it as anterior. ...Therefore by cause... we define time; but...how do we recognize which is the cause and which the effect? We assume... the anterior fact, the antecedent, is the cause of the... consequent. It is then by time that we define cause. ...Shall we escape from this vicious circle?

Any loss of identity prompts people to seek reassurance and rediscovery of themselves by testing, and even by violence. Today, the electric revolution, the wired planet, and the information environment involve everybody in everybody to the point of individual extinction.

The first remark we have to make, and which - though already presented more than once - cannot be too often repeated when the occasion seems to call for it, - is that what we call principle, aim, destiny, or the nature and idea of Spirit, is something merely general and abstract. Principle - Plan of Existence - Law - is a hidden, undeveloped essence, which as such - however true in itself - is not completely real.

Money is a corporate image depending on society for its institutional status.

Why in the world shouldn't they have regarded with awe and reverence that act by which the human race is perpetuated. Not every religion has to have St. Augustine's attitude to sex. Why even in our culture marriages are celebrated in a church, everyone present knows what is going to happen that night, but that doesn't prevent it being a religious ceremony.
