After it hath been seen how the obstinate and the ignorant of evil disposition are accustomed to dispute, it will further be shewn how disputes are wont to conclude; although others are so wary that without losing their composure, but with a sneer, a smile, a certain discreet malice, that which they have not succeeded in proving by argument - nor indeed can it be understood by themselves - nevertheless by these tricks of courteous disdain they pretend to have proven, endeavouring not only to conceal their own patently obvious ignorance but to cast it on to the back of their adversary. For they dispute not in order to find or even to seek Truth, but for victory, and to appear the more learned and strenuous upholders of a contrary opinion. Such persons should be avoided by all who have not a good breastplate of patience.

All truth, in the long run, is only common sense clarified.

For consequentialists, of course, the imperative to imagine the consequences of living in a world in which everyone would act as you choose to act leads to the conclusion that some practices are utterly untenable, not because they are irrational, but because they inflict consequential damage that is unwanted. In both cases, I would suggest, a potential action is figured as hypothetically reciprocal: one's own act comes back in the imagined form of another's act; another might act on me as I would act on the other, and the consequences are unacceptable because of those damaging consequences.

The best way to describe anyone is to give an example of the kind of thing he would do.

Concepts, like individuals, have their histories, and are just as incapable of withstanding the ravages of time as are individuals.

Kings will be tyrants from policy, when subjects are rebels from principle.

All sentiment is right; because sentiment has a reference to nothing beyond itself, and is always real, wherever a man is conscious of it. But all determinations of the understanding are not right; because they have a reference to something beyond themselves, to wit, real matter of fact; and are not always conformable to that standard.

Except for music, everything is a lie, even solitude, even ecstasy. Music, in fact, is the one and the other, only better.

The most important part of education - to teach the meaning of to know (in the scientific sense). The last statement in her notebook

Virtue can only flourish amongst equals.

What surrounds us we endure better for giving it a name - and moving on.

Put in a nut-shell, my thesis amounts to this. The repeated attempts made by Rudolf Carnap to show that the demarcation between science and metaphysics coincides with that between sense and nonsense have failed. The reason is that the positivistic concept of 'meaning' or 'sense' (or of verifiability, or of inductive confirmability, etc.) is inappropriate for achieving this demarcation - simply because metaphysics need not be meaningless even though it is not science. In all its variations demarcation by meaninglessness has tended to be at the same time too narrow and too wide: as against all intentions and all claims, it has tended to exclude scientific theories as meaningless, while failing to exclude even that part of metaphysics which is known as 'rational theology'.

If thou wilt be perfect, go and sell that thou hast, and give to the poor, and thou shalt have treasure in heaven: and come and follow me.

I will now tell you who are assembled here the wise sayings of Mazda, the praises of Ahura and the hymns of the Good Spirit, the sublime truth which I see rising out of these flames. You shall therefore harken to the Soul of Nature. Contemplate the beams of fire with a most pious mind. Every one, both men and women, ought to-day to choose his creed. Ye offspring of renowned ancestors, awake to agree with us. So preached Zoroaster, the proph of the Parsis, in one of his earliest sermons nearly 3,500 years ago.

I think that when friendship and perception of kinship ruled everything, no one killed any creature, because people thought the other animals were related to them.

Listen widely to remove your doubts and be careful when speaking about the rest and your mistakes will be few. See much and get rid of what is dangerous and be careful in acting on the rest and your causes for regret will be few. Speaking without fault, acting without causing regret: 'upgrading' consists in this.

The saying that beauty is but skin deep is but a skin-deep saying.

The composer reveals the innermost nature of the world, and expresses the profoundest wisdom in a language that his reasoning faculty does not understand, just as a magnetic somnambulist gives information about things of which she has no conception when she is awake. Therefore in the composer, more than in any other artist, the man is entirely separate and distinct from the artist.

Equally there is no rhythm when variations are not placed. There is a wealth of suggestions in the phrase "takes place". The change not only comes but it belongs; it had its definite place in a larger whole.

The Austrian Germans and Magyars will be set free and wreak a bloody revenge on the Slav barbarians. The general war which will then break out will smash this Slav Sonderbund and wipe out all these petty hidebound nations, down to their very names. The next world war will result in the disappearance from the face of the earth not only of reactionary classes and dynasties, but also of entire reactionary peoples. And that, too, is a step forward.

Once again, I experienced that overwhelming joy in the universe that I had felt in London outside the V and A. But this time, my consciousness of the world seemed larger, more complex. It was the mystic's sensation of oneness, of everything blending into everything else. Everything I looked at reminded me of something else, which also became present to my consciousness, as if I were simultaneously seeing a million worlds and smelling a million scents and hearing a million sounds-- not mixed up, but each separate and clear. I was overwhelmed with a sense of my smallness in the face of this vast, beautiful, objective universe, this universe whose chief miracle is that it exists, as well as myself. It is no dream, but a great garden in which life is trying to obtain a foothold. I experienced a desire to burst into tears of gratitude; then I controlled it, and the feeling subsided into a calm sense of immense, infinite beauty.

The suppression of liberty is always likely to be irrational.

Nothing, I am sure, calls forth the faculties so much as the being obliged to struggle with the world; and this is not a woman's province in a married state. Her sphere of action is not large, and if she is not taught to look into her own heart, how trivial are her occupations and pursuits! What little arts engross and narrow her mind!

If I had as clear an idea of ghosts, as I have of a triangle or a circle, I should not in the least hesitate to affirm that they had been created by God; but as the idea I possess of them is just like the ideas, which my imagination forms of harpies, gryphons, hydras, &c., I cannot consider them as anything but dreams, which differ from God as totally as that which is not differs from that which is.

The real is not only what can be reproduced, but that which is already reproduced, the hyper-real.

Every great study is not only an end in itself, but also a means of creating and sustaining a lofty habit of mind.

Not much younger than these (sc. Hermotimus of Colophon and Philippus of Mende) is Euclid, who put together the Elements, collecting many of Eudoxus' theorems, perfecting many of Theaetetus', and also bringing to irrefragable demonstration the things which were only somewhat loosely proved by his predecessors. This man lived in the time of the first Ptolemy. For Archimedes, who came immediately after the first (Ptolemy), makes mention of Euclid: and, further, they say that Ptolemy once asked him if there was in geometry any shorter way than that of the elements, and he answered that there was no royal road to geometry. He is then younger than pupils of Plato but older than Eratosthenes and Archimedes; for the latter were contemporary with one another, as Eratosthenes somewhere says.

To have a great man for an intimate friend seems pleasant to those who have never tried it; those who have, fear it.

A fate is not a punishment.

'Tis a grievous thing to be subject to an inferior.

Scientific and technological progress themselves are value-neutral. They are just very good at doing what they do. If you want to do selfish, greedy, intolerant and violent things, scientific technology will provide you with by far the most efficient way of doing so. But if you want to do good, to solve the world's problems, to progress in the best value-laden sense, once again, there is no better means to those ends than the scientific way.

Strictly speaking, the mass, as a psychological fact, can be defined without waiting for individuals to appear in mass formation. In the presence of one individual we can decide whether he is "mass" or not. The mass is all that which sets no value on itself - good or ill - based on specific grounds, but which feels itself "just like everybody," and nevertheless is not concerned about it; is, in fact, quite happy to feel itself as one with everybody else.

Tolerance and apathy are the last virtues of a dying society.

Did ye never read in the scriptures, The stone which the builders rejected, the same is become the head of the corner: this is the Lord's doing, and it is marvellous in our eyes? Therefore say I unto you, The kingdom of God shall be taken from you, and given to a nation bringing forth the fruits thereof. And whosoever shall fall on this stone shall be broken: but on whomsoever it shall fall, it will grind him to powder.

How shall the dead arise, is no question of my faith; to believe only possibilities, is not faith, but mere philosophy.

A habit of basing convictions upon evidence, and of giving to them only that degree of certainty which the evidence warrants, would, if it became general, cure most of the ills from which the world is suffering. But at present, in most countries, education aims at preventing the growth of such a habit, and men who refuse to profess belief in some system of unfounded dogmas are not considered suitable as teachers of the young.

Now who are the individuals who are the greatest benefactors of the living generation of mankind? I should say: Confucius and Lao-Tse; the Buddha; the Prophets of Israel and Judah; Zoroaster, Jesus, Muhammad; and Socrates.

What must be remembered in any case is that secret complicity that joins the logical and the everyday to the tragic.

For each new class which puts itself in the place of one ruling before it, is compelled, merely in order to carry through its aim, to represent its interests the common interest of all the members of society, that is, sality, and represent them as the only rational, universally valid ones. The class making a revolution appears from the very start, if only because it is opposed to a class, not as a class but as the representative of the whole of society; it appears as the whole mass of society confronting the one ruling class.

We should, out of decency, choose for ourselves the moment to disappear.

Genes and culture have co-evolved. But crudely, natural selection "designed" male human primates to hunt nonhumans and build coalitions of other male human primates in order to wage territorial wars of aggression. Nature didn't design us to become a scientific community and collaborate to overcome aging. It's difficult to imagine that any human enemy could inflict such gruesome damage on the victims as growing old. The ravages of aging strike down combatants and civilians alike. So the trillions of dollars that humans currently spend on ways to harm and kill each other ("defence") would be more fruitfully spent on defeating our common enemy. We should work together to build a "Triple S" civilisation of superlongevity, superhappiness and superintelligence.

Some of your hurts you have cured, And the sharpest you still have survived, But what torments of grief you endured From evils which never arrived!

Building worlds is not enough for the deeper urging mind; but a loving heart sates the striving spirit.

Having always lived in fear of being surprised by the worst, I have tried in every circumstance to get a head start, flinging myself into misfortune long before it occurred.

Not because Socrates said so, but because it is in truth my own disposition - and perchance to some excess - I look upon all men as my compatriots, and embrace a Pole as a Frenchman, making less account of the national than of the universal and common bond.

No amount of happiness enjoyed by some organisms can notionally justify the indescribable horrors of Auschwitz. [...] Nor can the fun and games outweigh the sporadic frightfulness of pain and despair that occurs every second of every day. For there's nothing inherently wrong with non-sentience or [...] non-existence; whereas there is something frightfully and self-intimatingly wrong with suffering.

The age of philosophy in the sense again that we are confronted more and more often with philosophical problems at an everyday level. It is not that you withdraw from daily life into a world of philosophical contemplation. On the contrary, you cannot find your way around daily life itself without answering certain philosophical questions. It is a unique time when everyone is, in a way, forced to be some kind of philosopher.

Religion comforts us for the defeat of our will to power. It adds new worlds to ours, and thus brings us hope of new conquests and new victories. We are converted to religion out of fear of suffocating within the narrow confines of this world.

I consider you the most honest and truthful of men, more honest and truthful than anyone; and if they say that your mind...that is, that you're sometimes afflicted in your mind, it's unjust. I made up my mind about that, and disputed with others, because, though you really are mentally afflicted (you won't be angry with that, of course; I'm speaking from a higher point of view), yet the mind that matters is better in you than in any of them. It's something, in fact, they have never dreamed of. For there are two sorts of mind: one that matters, and one that doesn't matter.
