What need is there of suspicious fear, since it is in thy power to inquire what ought to be done? And if thy seest clear, go by this way content, without turning back: but if thy dost not see clear, stop and take the best advisers. But if any other things oppose thee, go on according to thy powers with due consideration, keeping to that which appears to be just. For it is best to reach this object, and if thou dost fail, let thy failure be in attempting this. He who follows reason in all things is both tranquil and active at the same time, and also cheerful and collected.

But that which is useful is the better.

There are all kinds of sources of our knowledge; but none has authority ... The fundamental mistake made by the philosophical theory of the ultimate sources of our knowledge is that it does not distinguish clearly enough between questions of origin and questions of validity.

Be your money's master, not its slave.

As soon as the land of any country has all become private property, the landlords, like all other men, love to reap where they never sowed, and demand a rent even for its natural produce.

Scientific truth is characterized by its exactness and the certainty of its predictions. But these admirable qualities are contrived by science at the cost of remaining on a plane of secondary problems. leaving intact the ultimate and decisive questions. ... Yet science is but a small part of the human mind and organism. Where it stops, man does not stop.

Truth is great and its effectiveness endures. 

The mind which is free from passions is a citadel, for man has nothing more secure to which he can fly for refuge and for the future be inexpugnable. He then who has not seen this is an ignorant man: but he who has seen it and does not fly to this refuge is unhappy.

I saw a Divine Being. I'm afraid I'm going to have to revise all my various books and opinions.

On a certain level of generality A which I call the ground level, you have certain theorems that have been proved and certain unsolved problems P of recognised interest. Suppose you discover a generalisation of one of these theorems and thereby rise to a higher level of generality A'. Write it up, but lock it away in a drawer - unless or until it serves to solve one of the problems P on the ground level... But the deeper one drives the spade the harder the digging gets; maybe it has become too hard for us unless we are not given some outside help, be it even by such devilish devices as high-speed computing machines.

Far or forgot to me is near; Shadow and sunlight are the same; The vanished gods to me appear; And one to me are shame and fame.

We are, like Nebuchadnezzar, dethroned, bereft of reason, and eating grass like an ox.

The young today cannot follow narrative but they are alert to drama. They cannot bear description but they love landscape and action.

He who has begun has half done. Dare to be wise; begin!

Let us go on committing suicide by working among our people, and let them dream life just as the lake dreams the sky.

I had hoped that out of so many stories you would at least have produced one or two, which could hardly be questioned, and which would clearly show that ghosts or spectres exist. The case you relate... seems to me laughable. In like manner it would be tedious here to examine all the stories of people, who have written on these trifles. To be brief, I cite the instance of Julius Caesar, who, as Suetonius testifies, laughed at such things and yet was happy. ...And so should all who reflect on the human imagination, and the effects of the emotions, laugh at such notions; whatever Lavater and others, who have gone dreaming with him in the matter, may produce to the contrary.

He who receives a benefit with gratitude, repays the first installment of it.

I prefer a short life with width to a narrow one with length.

Here is a fulfillment of long centuries of civilization and culture; here, in romantic love, more than the triumph of thought or the victories of power is the topmost reach of human beings.

Ethics seems a morass which we have to cross, but get hopelessly bogged in when we make the attempt.

The healthy man does not torture others-generally it is the tortured who turn into torturers.

To die is to wander.

We rarely find anyone who can say he has lived a happy life, and who, content with his life, can retire from the world like a satisfied guest.

My soul is exceeding sorrowful, even unto death: tarry ye here, and watch with me.

A jealous lover of human liberty, deeming it the absolute condition of all that we admire and respect in humanity, I reverse the phrase of Voltaire, and say that, if God really existed, it would be necessary to abolish him. Ch. II; Variants or variant translations of this statement have also been attributed to Bakunin: The first revolt is against the supreme tyranny of theology, of the phantom of God. As long as we have a master in heaven, we will be slaves on earth. A boss in Heaven is the best excuse for a boss on earth, therefore If God did exist, he would have to be abolished.

It is because you yourself fear the propaganda created, after all, only by the stupidity of your own bigots.

Seek, therefore, thyself! But in finding oneself, does not one find one's own nothingness? ...Carlyle answers (Past and Present, book iii, chap. xi.). "The latest Gospel in the world is, Know thy work and do it. Know thyself: long enough has that poor self of thine tormented thee; thou wilt never get to know it, I believe! Think it thy business, this of knowing thyself; thou art an unknowable individual: know what thou canst work at; and work at it, like Hercules. That will be thine better plan." ...and what is my work? - without thinking about myself, is to love God. ...And on the other hand, in loving God in myself, am I not loving myself more than God, am I not loving myself in God?

What am I, other than a chance in the infinite probabilities of not having been!

A paradise of inward tranquility seems to be faith's usual result.

How good is it to remember one's insignificance: that of a man among billions of men, of an animal amid billions of animals; and one's abode, the earth, a little grain of sand in comparison with Sirius and others, and one's life span in comparison with billions on billions of ages. There is only one significance, you are a worker. The assignment is inscribed in your reason and heart and expressed clearly and comprehensibly by the best among the beings similar to you. The reward for doing the assignment is immediately within you. But what the significance of the assignment is or of its completion, that you are not given to know, nor do you need to know it. It is good enough as it is. What else could you desire?

Writers, poets, painters, musicians, philosophers, political thinkers, to name only a few of the categories affected, must woo their readers, viewers, listeners, from distraction. To this we must add, for simple realism demands it, that these same writers, painters, etc., are themselves the children of distraction. As such, they are peculiarly qualified to approach the distracted multitudes. They will have experienced the seductions as well as the destructiveness of the forces we have been considering here. This is the destructive element in which we do not need to be summoned to immerse ourselves, for we were born to it.

This same Man-of-Letters Hero must be regarded as our most important modern person. He, such as he may be, is the soul of all.

The suppression of liberty is always likely to be irrational.

An ethos of freedom stops power from solidifying into domination and makes sure it remains an open game.

The chief danger to philosophy is narrowness in the selection of evidence.

The thought of every group is seen as arising out of its life conditions. Thus, it becomes the task of the sociological history of thought to anlayse without regard for party biases all the factors in the actually existing social situation which may influence thought. This sociologically oriented history of ideas is destined to provide modern men with a revised view of the whole historical process.

When you have understood that nothing is, that things do not even deserve the status of appearances, you no longer need to be saved, you are saved, and miserable forever.

It seems to me now that mathematics is capable of an artistic excellence as great as that of any music, perhaps greater; not because the pleasure it gives (although very pure) is comparable, either in intensity or in the number of people who feel it, to that of music, but because it gives in absolute perfection that combination, characteristic of great art, of godlike freedom, with the sense of inevitable destiny; because, in fact, it constructs an ideal world where everything is perfect and yet true.

Unbelievers (so called) as well as of believers, there are many species, including almost every variety of moral type. But the best among them, as no one who has had opportunities of really knowing them will hesitate to affirm (believers rarely have that opportunity), are more genuinely religious, in the best sense of the word religion, than those who exclusively arrogate to themselves the title.

People crushed by law, have no hopes but from power. If laws are their enemies, they will be enemies to laws; and those who have much to hope and nothing to lose, will always be dangerous.

It is easy to see that this problem can be solved neither in theoretical nor in practical philosophy, but only in a higher discipline, which is the link that combines them, and neither theoretical nor practical, but both at once.

The nuclear bomb will turn warfare into the juggling of images.

The tyrant has arisen, and the king and oligarchy and aristocracy and democracy, because men are not contented with that one perfect ruler, and do not believe that there could ever be any one worthy of such power or willing and able by ruling with virtue and knowledge to dispense justice and equity rightly to all, but that he will harm and kill and injure any one of us whom he chooses on any occasion, since they admit that if such a man as we describe should really arise, he would be welcomed and would continue to dwell among them, directing to their weal as sole ruler a perfectly right form of government. But, as the case now stands, since, as we claim, no king is produced in our states who is, like the ruler of the bees in their hives, by birth pre-eminently fitted from the beginning in body and mind, we are obliged, as it seems, to follow in the track of the perfect and true form of government by coming together and making written laws.

When one is a stranger to oneself then one is estranged from others too. If one is out of touch with oneself, then one cannot touch others.

The sociologist permits himself to see only what is acceptable to his colleagues.

It occurs to me that artists go forward by going backward, something which I have nothing against intrinsically when it is a reproduced retreat - as is the case with the better artists. But it does not seem right that they stop with the historical themes already given and, so to speak, think that only these are suitable for poetic treatment, because these particular themes, which intrinsically are no more poetic than others, are now again animated and inspirited by a great poetic nature. In this case the artists advance by marching on the spot. - Why are modern heroes and the like not just as poetic? Is it because there is so much emphasis on clothing the content in order that the formal aspect can be all the more finished?
