. ... the prince says that the world will be saved by beauty! And I maintain that the reason he has such playful ideas is that he is in love.

The task of power is to transform the always possible 'no' into a 'yes.'

Every man takes the limits of his own field of vision for the limits of the world.

Middle age begins with marriage; for then work and responsibility replace carefree play, passion surrenders to the limitations of social order, and poetry yields to prose.

With an ignorant man thou shouldst not become a confederate and associate.

But Hermotimus, the Colophonian, rendered more abundant what was formerly published by Eudoxus and Theætetus, and invented a multitude of elements, and wrote concerning some geometrical places. But Philippus the Mendæan, a disciple of Plato, and by him inflamed in the mathematical disciplines, both composed questions, according to the institutions of Plato, and proposed as the object of his enquiry whatever he thought conduced to the Platonic philosophy.

Invention is the mother of all necessities.

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.

One common strategy on which we should all be able to agree is to take steps to reduce the risk of human extinction when those steps are also highly effective in benefiting existing sentient beings. For example, eliminating or decreasing the consumption of animal products will benefit animals, reduce greenhouse gas emissions, and lessen the chances of a pandemic resulting from a virus evolving among the animals crowded into today's factory farms, which are an ideal breeding ground for viruses. That therefore looks like a high-priority strategy.

But how shall we expect charity towards others, when we are uncharitable to ourselves? Charity begins at home, is the voice of the world, yet is every man his greatest enemy, and as it were, his own executioner.

One who liberates his country by killing a tyrant is to be praised and rewarded.

Those who used to sacrifice animals did not take them for beasts. And even the Middle Ages, which condemned and punished them in due form, was in this way much closer to them than we are, we who are filled with horror at this practice. They held them to be guilty: which was a way of honoring them. We take them for nothing, and it is on this basis that we are "human" with them. We no longer sacrifice them, we no longer punish them, and we are proud of it, but it is simply that we have domesticated them, worse: that we have made of them a racially inferior world, no longer even worthy of our justice, but only of our affection and social charity, no longer worthy of punishment and of death, but only of experimentation and extermination like meat from the butchery.

...what the freedom is that I love, and that to which I think all men intitled. It is not solitary, unconnected, individual, selfish Liberty. As if every Man was to regulate the whole of his Conduct by his own will. The Liberty I mean is social freedom. It is that state of things in which Liberty is secured by the equality of Restraint; A Constitution of things in which the liberty of no one Man, and no body of Men and no Number of men, can find Means to trespass on the liberty of any Person, or any description of Persons in the Society. This kind of liberty is indeed but another name for Justice, as ascertained by wise Laws, and secured by well-constructed institutions.

There are many things of which a wise man might wish to be ignorant.

Most shocking of all is alledging the Sacred Scriptures to favour this wicked practice. One would have thought none but infidel cavillers would endeavour to make them appear contrary to the plain dictates of natural light, and Conscience, in a matter of common Justice and Humanity; which they cannot be. Such worthy men, as referred to before, judged otherways; Mr. Baxter declared, the Slave-Traders should be called Devils, rather than Christians; and that it is a heinous crime to buy them.

Insurrection ... never brings about the desired improvement. For insurrection lacks discernment; it generally harms the innocent more than the guilty. Hence, no insurrection is ever right, no matter how right the cause it seeks to promote.

The sky was horribly dark, but one could distinctly see tattered clouds, and between them fathomless black patches. Suddenly I noticed in one of these patches a star, and began watching it intently. That was because that star had given me an idea: I decided to kill myself that night.

This is a fine saying of Plato: That he who is discoursing about men should look also at earthly things as if he viewed them from some higher place; should look at them... a mixture of all things and an orderly combination of contraries.

Of the evils most liable to attend on any sort of early proficiency, and which often fatally blights its promise, my father most anxiously guarded against. This was self-conceit. He kept me, with extreme vigilance, out of the way of hearing myself praised, or of being led to make self-flattering comparisons between myself and others. From his own intercourse with me I could derive none but a very humble opinion of myself; and the standard of comparison he always held up to me, was not what other people did, but what a man could and ought to do. He completely succeeded in preserving me from the sort of influences he so much dreaded. I was not at all aware that my attainments were anything unusual at my age.

The only fence against the world is a thorough knowledge of it, into which a young gentleman should be enter'd by degrees, as he can bear it; and the earlier the better, so he be in safe and skillful hands to guide him.

Never trouble another for what you can do yourself.

The good of the people must be the great purpose of government. By the laws of nature and of reason, the governors are invested with power to that end. And the greatest good of the people is liberty. It is to the state what health is to the individual.

It is certain that we cannot escape anguish, for we are anguish.

A definition may be very exact, and yet go but a very little way towards informing us of the nature of the thing defined.

My car and my adding machine understand nothing: they are not in that line of business.

When men and women agree, it is only in their conclusions; their reasons are always different.

There is no disease so destructive as lust.

No, no, you are not thinking, you are just being logical.

The fundamental tenet of Steiner's teaching is that if we take the trouble to recognize the independent existence of the inner worlds of thought, and keep the mind turned in that direction, we shall soon become increasingly conscious of their reality. We are not, as Sartre believed, stranded in the universe of matter like a whale on a beach. That inner world is our natural home. Moreover, once we grasp this truth, we can also recognize that we ourselves possess an "essential ego," a "true self," a fundamental identity that goes far beyond our usual feeble sense of being "me."

No man has received from nature the right to give orders to others. Freedom is a gift from heaven, and every individual of the same species has the right to enjoy it as soon as he is in enjoyment of his reason.

Resting on your laurels is as dangerous as resting when you are walking in the snow. You doze off and die in your sleep.

And now the sagacious reader, who is capable of reading into these lines what does not stand written in them, but is nevertheless implied, will be able to form some conception of the serious feelings with which I then set foot in Emmendingen.

It is a great force, and a great fortune, to be able to live without any ambition whatever. I aspire to it, but the very fact of so aspiring still participates in ambition.

Depart then satisfied, for he also who releases thee is satisfied.

As a genius of construction man raises himself far above the bee in the following way: whereas the bee builds with wax that he gathers from nature, man builds with the far more delicate conceptual material which he first has to manufacture from himself.

If everything must have a cause, then God must have a cause. If there can be anything without a cause, it may just as well be the world as God, so that there cannot be any validity in that argument. It is exactly of the same nature as the Hindu's view, that the world rested upon an elephant and the elephant rested upon a tortoise; and when they said, "How about the tortoise?" the Indian said, "Suppose we change the subject." The argument is really no better than that.

In all things success depends on previous preparation, and without such previous preparation there is sure to be failure. If what is to be spoken be previously determined, there will be no stumbling. If affairs be previously determined, there will be no difficulty with them. If one's actions have been previously determined, there will be no sorrow in connection with them. If principles of conduct have been previously determined, the practice of them will be inexhaustible.

The Utopianism of the standpoint which expects an era of peace and retrenchment of militarism in the present social order is plainly revealed in the fact that it is having recourse to project making. For it is typical of Utopian strivings that, in order to demonstrate their practicability, they hatch "practical" recipes with the greatest possible details. To this also belongs the project of the "United States of Europe" as a basis for the limitation of international militarism.

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.

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

I am a mariner of Odysseus with heart of fire but with mind ruthless and clear.

Once ... I was offered a lift by some carters ... It was the Thursday before Easter. I was seated in the first cart, with a strong, red, coarse carman, who evidently drank. On entering a village we saw a well-fed, naked, pink pig being dragged out of the first yard to be slaughtered. It squealed in a dreadful voice, resembling the shriek of a man. Just as we were passing they began to kill it. A man gashed its throat with a knife. The pig squealed still more loudly and piercingly, broke away from the men, and ran off covered with blood. Being near-sighted I did not see all the details. I saw only the human-looking pink body of the pig and heard its desperate squeal; but the carter saw all the details and watched closely. They caught the pig, knocked it down, and finished cutting: its throat. When its squeals ceased the carter sighed heavily. 'Do men really not have to answer for such things?' he said.

Being summoned by the Athenians out of Sicily to plead for his life, Alcibiades absconded, saying that that criminal was a fool who studied a defence when he might fly for it.

He came in sight of a pass guarded by armed men. 'you cannot pass ... Do you not know that all this country belongs to the Spirit of the Age? ... Here Enlightenment, take this fugitive to our Master.'

Logical consequences are the scarecrows of fools and the beacons of wise men.

Remember Bostrom's definition of existential risk, which refers to the annihilation not of human beings, but of "Earth-originating intelligent life." The replacement of our species by some other form of conscious intelligent life is not in itself, impartially considered, catastrophic. Even if the intelligent machines kill all existing humans, that would be...a very small part of the loss of value that Parfit and Bostrom believe would be brought about by the extinction of Earth-originating intelligent life. The risk posed by the development of AI, therefore, is not so much whether it is friendly to us, but whether it is friendly to the idea of promoting wellbeing in general, for all sentient beings it encounters, itself included.

Man is a tool-using animal...Without tools he is nothing, with tools he is all.

If there ever are great revolutions there, they will be caused by the presence of the blacks upon American soil. That is to say, it will not be the equality of social conditions but rather their inequality which may give rise thereto.
