Fanaticism is the danger of the world, and always has been, and has done untold harm. I might almost say that I was fanatical against fanaticism.

We all labour against our own cure, for death is the cure of all diseases.

Understand me well. My appeal is to observation - observation that each of you must make for himself.

To see ourselves as others see us is a most salutary gift. Hardly less important is the capacity to see others as they see themselves.

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.

The vices respectively fall short of or exceed what is right in both passions and actions, while virtue both finds and chooses that which is intermediate.

To be is to be cornered.

The "I" who speaks in this book is by no means the author. Rather, the author wishes that the reader may come to see himself in this "I": that the reader may not simply relate to what is said here as he would to history, but rather that while reading he will actually converse with himself, deliberate back and forth, deduce conclusions, make decisions like his representative in the book, and through his own work and reflection, purely out of his own resources, develop and build within himself the philosophical disposition that is presented to him in this book merely as a picture.

There is much pleasure to be gained from useless knowledge.

Those who believe that they are exclusively in the right are generally those who achieve something.

The history of science is full of revolutionary advances that required small insights that anyone might have had, but that, in fact, only one person did.

I like thought which preserves a whiff of flesh and blood, and I prefer a thousand times an idea rising from sexual tension or nervous depression to empty abstraction.

Getting rid of predation isn't a matter of moralising. A python who kills a small human child isn't morally blameworthy. Nor is a lion who hunts and kills a terrified zebra. In both cases, the victim suffers horribly. But the predator lacks the empathetic and mind-reading skills needed to understand the implications of what s/he is doing. Some humans still display a similar deficit. From the perspective of the victim, the moral status or (lack of) guilty intent of a human or nonhuman predator is irrelevant. Either way, to stand by and watch the snake asphyxiate a child would be almost as morally abhorrent as to kill the child yourself. So why turn this principle on its head with beings of comparable sentience to human infants and toddlers? With power comes complicity.

Fact be vertuous, or vicious, as Fortune pleaseth.

All things in nature become identical with the phenomena they present when submitted to the practices of our laboratories, whose problems no less than their apparatus express in turn the problems and interests of society as it is. This view may be compared with that of a criminologist maintaining that trustworthy knowledge of a human being can be obtained only by the well-tested and streamlined examining methods applied to a suspect in the hands of the metropolitan police.

With the abolition of otium and of the ego no aloof thinking is left. ... Without otium philosophical thought is impossible, cannot be conceived or understood.

Strong as it looks at the outset, State-agency perpetually disappoints every one. Puny as are its first stages, private efforts daily achieve results that astound the world.

Fear for the Other, fear for the other man's death is my fear, but is in no way an individual's taking fright.

Through laziness and cowardice a large part of mankind, even after nature has freed them from alien guidance, gladly remain immature. It is because of laziness and cowardice that it is so easy for others to usurp the role of guardians. It is so comfortable to be a minor!

In the past, there was a small leisure class and a larger working class. The leisure class enjoyed advantages for which there was no basis in social justice; this necessarily made it oppressive, limited its sympathies, and caused it to invent theories by which to justify its privileges.

Gratitude looks to the past and love to the present; fear, avarice, lust, and ambition look ahead.

Nothing made a happy slave, but a degraded man. In proportion as the mind grew callous to its degradation, and all sense of manly pride was lost, the slave felt comfort. In fact, he was no longer a man. If he were to define a man, he would say with Shakspeare,"Man is a being, holding large discourse,Looking before and after."A slave was incapable of either looking before or after.

The man who holds the divine theory of life recognizes life not in his own individuality, and not in societies of individualities (in the family, the clan, the nation, the tribe, or the government), but in the eternal undying source of life-in God; and to fulfill the will of God he is ready to sacrifice his individual and family and social welfare. The motor power of his life is love. And his religion is the worship in deed and in truth of the principle of the whole-God.

The sensate body possesses an art of interrogating the sensible according to its own wishes, an inspired exegesis The Visible and the Invisible, trans.

Never would the humanities or psychoanalysis have existed if it had been miraculously possible to reduce man to his "rational" behaviors.

Bourgeois society is ruled by equivalence. It makes the dissimilar comparable by reducing it to abstract quantities. To the Enlightenment, that which does not reduce to numbers, and ultimately to the one, becomes illusion.

All those of you who rejoice in peace, now it is time to judge the truth....Undoubtedly in days gone by there were holy men as Scripture tells,For God stated that he left behind seven thousand men in safety,And there are many priests and kings who are righteous under the law,There you find so many of the prophets, and many of the people too.Tell me which of the righteous of that time claimed an altar for himself?That wicked nation perpetrated a very large number of crimes,They sacrificed to idols and may prophets were put to death,Yet not a single one of the righteous withdrew from unity.The righteous endured the unrighteous while waiting for the winnower:They all mingled in one temple but were not mingled in their hearts;They said such things against them yet they had a single altar.

Critical social science attempts to determine when theoretical statements grasp invariant regularities of social action as such and when they express ideologically frozen relations of dependence that can in principle be transformed.

The cheapest sort of pride is national pride; for if a man is proud of his own nation, it argues that he has no qualities of his own of which he can be proud; otherwise he would not have recourse to those which he shares with so many millions of his fellowmen. The man who is endowed with important personal qualities will be only too ready to see clearly in what respects his own nation falls short, since their failings will be constantly before his eyes. But every miserable fool who has nothing at all of which he can be proud adopts, as a last resource, pride in the nation to which he belongs; he is ready and glad to defend all its faults and follies tooth and nail, thus reimbursing himself for his own inferiority.

Why do I think that we, the intellectuals, are able to help? Simply because we, the intellectuals, have done the most terrible harm for thousands of years. Mass murder in the name of an idea, a doctrine, a theory, a religion - that is all our doing, our invention: the invention of the intellectuals. If only we would stop setting man against man - often with the best intentions - much would be gained. Nobody can say that it is impossible for us to stop doing this.

This idea of weapons of mass extermination is utterly horrible and is something which no one with one spark of humanity can tolerate. I will not pretend to obey a government which is organising a mass massacre of mankind.

"I am like a broken puppet whose eyes have fallen inside." This remark of a mental patient weighs more heavily than a whole stack of works on introspection.

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.

I might try to save the view that 'future contingents' have no truth value by saying that even present-tense statements have no truth value if they refer to the outcome of events that are so far away that a causal signal informing me of the outcome could not have reached me-now without traveling faster than light. In other words, I might attempt saying that statements about events that are in neither the upper half nor the lower half of my light-cone have no truth value. In addition, statements about events in the upper half of my light-cone have no truth value, since they are in my future according to every coordinate system. So only statements about events in the lower half of my light-cone have a truth value; only events that are in 'my past* according to all observers are determined.

Gentile himself call his doctrine 'absolute formalism': there is no; 'matter' apart from the pure 'form' of acting. 'The only matter there is in the spiritual act is the form itself, as activity.'

Eating and reading are two pleasures that combine admirably.

Ideal legislators do not vote their interests.

The man-like Apes... have certain characters of structure and of distribution in common.

Humanity may endure the loss of everything: all its possessions may be torn away without infringing its true dignity; - all but the possibility of improvement.

The Path is not far from man. When men try to pursue a course, which is far from the common indications of consciousness, this course cannot be considered The Path.

Each of us believes, quite unconsciously of course, that we alone pursue the truth, which the rest are incapable of seeking out and unworthy of attaining. This madness is so deep-rooted and so useful that it is impossible to realize what would become of each of us if it were someday to disappear.

For joys fall not to the rich alone, nor has he lived ill, who from birth to death has passed unknown.

Plato and his objectivistic successors ... preserved the awareness of differences that pragmatism has been invented to deny-the difference between thinking in the laboratory and in philosophy, and consequently the difference between the destination of mankind and its present course.

Many modern philosophers claim that probability is relation between an hypothesis and the evidence for it.

There is geometry in the humming of the strings. There is music in the spacings of the spheres.

The greatest problem for the human race, to the solution of which Nature drives man, is the achievement of a universal civic society which administers law among men.

It's my belief that the Universe possesses, in its essence, fractal properties of a very complex sort and that the pursuit of science shares those properties. It follows that any part of the Universe that remains un-understood, and any part of scientific investigation that remains unresolved, however small that might be in comparison to what is understood and resolved, contains within it all the complexity of the original. Therefore, we'll never finish. No matter how far we go, the road ahead will be as long as it was at the start, and that's the secret of the Universe.

The deepest and most organic death is death in solitude, when even light becomes a principle of death. In such moments you will be severed from life, from love, smiles, friends and even from death. And you will ask yourself if there is anything besides the nothingness of the world and your own nothingness.

Assembled in a crowd, people lose their powers of reasoning and their capacity for moral choice.

Miracles are propitious accidents, the natural causes of which are too complicated to be readily understood.
