A good reputation is more valuable than money.

I have observed that even the barbarians across the Rhine sing savage songs composed in language not unlike the croaking of harsh-voiced birds, and that they delight in such songs. For I think it is always the case that inferior musicians, though they annoy their audiences, give very great pleasure to themselves.

Whenever our neighbour's house is on fire, it cannot be amiss for the engines to play a little on our own.

Revolutions never go backwards.

It is remarkable, that almost all speakers and writers feel it to be incumbent on them, sooner or later, to prove or to acknowledge the personality of God. ... In reading a work on agriculture, we have to skip the author's moral reflections, and the words "Providence" and "He" scattered along the page, to come at the profitable level of what he has to say. What he calls his religion is for the most part offensive to the nostrils. ... There is more religion in men's science than there is science in their religion.

I do not trust my eyes to tell me what a man is: I have a better and more trustworthy light by which I can distinguish what is true from what is false: let the mind find out what is good for the mind.

I hold in fact(1) That small portions of space are in fact of a nature analogous to little hills on a surface which is on the average flat; namely, that the ordinary laws of geometry are not valid in them.(2) That this property of being curved or distorted is continually being passed on from one portion of space to another after the manner of a wave.(3) That this variation of the curvature of space is what really happens in that phenomenon which we call the motion of matter, whether ponderable or etherial.(4) That in the physical world nothing else takes place but this variation, subject possibly to the law of continuity.

If what we are discussing were a point of law or of the humanities, in which neither true nor false exists, one might trust in subtlety of mind and readiness of tongue and in the greater experience of the writers, and expect him who excelled in those things to make his reasoning most plausible, and one might judge it to be the best. But in the natural sciences, whose conclusions are true and necessary and have nothing to do with human will, one must take care not to place oneself in the defense of error; for here a thousand Demostheneses and a thousand Aristotles would be left in the lurch by every mediocre wit who happened to hit upon the truth for himself. Therefore, Simplicio, give up this idea and this hope of yours that there may be men so much more learned, erudite, and well-read than the rest of us as to be able to make that which is false become true in defiance of nature.

Agricultural association, which in all ages has been deemed impossible, would produce results of unbounded magnificence the rigorous demonstrations, the mathematical calculations by which these results will be verified, will not, however, prevent the picture of the future harmony and happiness which they present from repelling minds habituated to the miseries and wretchedness of our present civilization. The Theory of Social Organization.

An appeal to his alarm is never a good plan to rid oneself of a spirited young man.

I believe that man is the product of natural evolution that is born from the conflict of being a prisoner and separated from nature, and from the need to find unity and harmony with it.

The kingdom of heaven can be compared to a king who wanted to settle accounts with his slaves.

Let us have the candor to acknowledge that what we call "the economy" or "the free market" is less and less distinguishable from warfare. For about half of the last century, we worried about world conquest by international communism. Now with less worry (so far) we are witnessing world conquest by international capitalism. Though its political means are milder (so far) than those of communism, this newly internationalized capitalism may prove even more destructive of human cultures and communities, of freedom, and of nature. Its tendency is just as much toward total dominance and control.

Other vices can be concealed and cherished in secret; anger shows itself openly and appears in the countenance, and the greater it is, the more plainly it boils forth. Do you not see how in all animals certain signs appear before they proceed to mischief, and how their entire bodies put off their usual quiet appearance and stir up their ferocity? Boars foam at the mouth and sharpen their teeth by rubbing them against trees, bulls toss their horns in the air and scatter the sand with blows of their feet

The many are mean; only the few are noble.

Yet God hath not only granted these faculties, by which we may bear every event without being depressed or broken by it, but like a good prince and a true father, hath placed their exercise above restraint, compulsion, or hindrance, and wholly within our own control.

Mathematical and physiological researches have shown that the space of experience is simply an actual case of many conceivable cases, about whose peculiar properties experience alone can instruct us.

To spare the guilty is to injure the innocent.

We may with advantage at times forget what we know.

The controlling Intelligence understands its own nature, and what it does, and whereon it works.

I suddenly stopped and looked out at the sea and thought, my God, how beautiful this is ... for 26 years I had never really looked at it before.

Does a man of sense run after every silly tale of hobgoblins or fairies, and canvass particularly the evidence? I never knew anyone, that examined and deliberated about nonsense who did not believe it before the end of his enquiries.

If each us had a different kind of sense perception — if we could only perceive things now as a bird, now as a worm, now as a plant, or if one of us saw a stimulus as red, another as blue, while a third even heard the same stimulus as a sound, then no one would speak of such a regularity of nature, rather, nature would be grasped only as a creation which is subjective in the highest degree. After all, what is a law of nature as such for us? We are not acquainted with it in itself, but only with its effects, which means in its relation to other laws of nature which, in turn, are known to us only as sums of relations. Therefore all these relations always refer again to others and are thoroughly incomprehensible to us in their essence.

One loves to possess arms, though they hope never to have occasion for them.

I will follow the good side right to the fire, but not into it if I can help it.

As soon as laws are necessary for men, they are no longer fit for freedom.

A criminal who, having renounced reason ... hath, by the unjust violence and slaughter he hath committed upon one, declared war against all mankind, and therefore may be destroyed as a lion or tyger, one of those wild savage beasts with whom men can have no society nor security. And upon this is grounded the great law of Nature, "Whoso sheddeth man's blood, by man shall his blood be shed."

In the dominant Western religious system, the love of God is essentially the same as the belief in God, in God's existence, God's justice, God's love. The love of God is essentially a thought experience. In the Eastern religions and in mysticism, the love of God is an intense feeling experience of oneness, inseparably linked with the expression of this love in every act of living.

What is imposed on us by birth and environment is what we are called upon to overcome.

Liberalism - it is well to recall this today-is the supreme form of generosity; it is the right which the majority concedes to minorities and hence it is the noblest cry that has ever resounded in this planet. It announces the determination to share existence with the enemy; more than that, with an enemy which is weak. It was incredible that the human species should have arrived at so noble an attitude, so paradoxical, so refined, so acrobatic, so anti-natural. Hence, it is not to be wondered at that this same humanity should soon appear anxious to get rid of it. It is a discipline too difficult and complex to take firm root on earth.

A word spoken in season, at the right moment, is the mother of ages.

It is of great importance to observe that the character of every man is, in some degree, formed by his profession. A man of sense may only have a cast of countenance that wears off as you trace his individuality, whist the weak, common man has scarcely ever any character, but what belongs to the body; at least, all his opinions have been so steeped in the vat consecrated by authority, that the faint spirit which the grape of his own vine yields, cannot be distinguished.

The errors of Communism must be rectified; but there is no necessity for giving up the name, which is a simple assertion of the paramount importance of Social Feeling. However, now that we have happily passed from monarchy to republicanism, the name of Communist is no longer indispensable; the word Republican expresses the meaning as well, and without the same danger. Positivism, then, has nothing to fear from Communism; on the contrary, it will probably be accepted by most Communists among the working classes, especially in France where abstractions have but little influence on minds thoroughly emancipated from theology. The people will gradually find that the solution of the great social problem which Positivism offers is better than the Communistic solution.

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.

Spontaneous love can reach the point of despair, shows that it is in despair, that even when it is happy it loves with the power of despair.

Merit is a work for the sake of which Christ gives rewards. But no such work is to be found, for Christ gives by promise. Just as if a prince should say to me, "Come to me in my castle, and I will give you a hundred florins." I do a work, certainly, in going to the castle, but the gift is not given me as the reward of my work in going, but because the prince promised it to me.

Rohde became more and more firmly bound to the bourgeois world, its institutions and accepted opinions. ... The contrast between the two natures makes Rohde and Nietzsche exemplary representatives of two distinctive worlds. In their youth they both live in the realm of boundless possibilities and feel an affinity through the exuberance of their noble aspirations. Subsequently they go in opposite directions. Nietzsche remains young, leaving concrete reality as his task assumes existential import. Rohde grows old, bourgeois, stable, and skeptical. Hence courage is a fundamental trait in Nietzsche, plaintive self-irony in Rohde. ... Rohde retained the interests but not the attitudes of his youth; he looked to the world of the Greeks for the object of his contemplation rather than the norm of obligation.

A special kind of beauty exists which is born in language, of language, and for language.

Space, subjectively, is the coexistence of perceptions - perceiving two objects at once.

The art of life is more like the wrestler's art than the dancer's, in respect of this, that it should stand ready and firm to meet onsets which are sudden and unexpected.

Underlying even the so-called problem of knowledge there is simply this human feeling, just as underlying the inquiry into the "why," the cause, there is simply the search for the "wherefore," the end. All the rest is either to deceive oneself or to wish to deceive others; and to wish to deceive others in order to deceive oneself.

It is a rough road that leads to the heights of greatness.

We want no foreign examples to rekindle in us the flame of liberty. The example of our own ancestors is abundantly sufficient to maintain the spirit of freedom in its full vigour, and to qualify it in all its exertions. The example of a wise, moral, well-natured, and well-tempered spirit of freedom, is that alone which can be useful to us, or in the least degree reputable or safe. Our fabric is so constituted; one part of it bears so much on the other, the parts, are so made for one another, and for nothing else, that to introduce any foreign matter into it, is to destroy it.

I believe in intuitions and inspirations. I sometimes feel that I am right. I do not know that I am. When two expeditions of scientists, financed by the Royal Academy, went forth to test my theory of relativity, I was convinced that their conclusions would tally with my hypothesis. I was not surprised when the eclipse of May 29, 1919, confirmed my intuitions. I would have been surprised if I had been wrong.

I urge you to please notice when you are happy, and exclaim or murmur or think at some point, "If this isn't nice, I don't know what is."

Hardness and softness, roughness and smoothness, moonlight and sunlight present themselves in our recollection not preeminently as sensory contents but as certain kinds of symbioses, certain ways outside has of invading us and certain ways we have of meets this invasion...

A rationalist, as I use the word, is a man who attempts to reach decisions by argument and perhaps, in certain cases, by compromise, rather than by violence. He is a man who would rather be unsuccessful in convincing another man by argument than successful in crushing him by force, by intimidation and threats, or even by persuasive propaganda.

Persons of genius, it is true, are, and are always likely to be, a small minority; but in order to have them, it is necessary to preserve the soil in which they grow. Genius can only breathe freely in an atmosphere of freedom.
