Natural selection is like artificial selection, but without the human chooser. Instead of a human deciding which offspring shall die in which shall reproduce, nature 'decides'. The quotation marks are vital because nature doesn't consciously decide. This might seem too obvious to emphasize, but you'd be surprised by the number of people who think natural selection implies some kind of personal choice. They couldn't be more wrong. It just is the case that some offspring are more likely to die while others have what it takes to survive and reproduce. Therefore, as the generations go by, the average, typical creature in the population becomes ever better at the arts of surviving and reproducing. Ever better, I should specify, when, when measured against some absolute standard.

I do not advocate burning your ship to get rid of the cockroaches.

Anarchy, in its own nature, is an evil of short duration. The more horrible are the mischiefs it inflicts, the more does it hasten to a close.

At the approach of danger there are always two voices that speak with equal force in the heart of man: one very reasonably tells the man to consider the nature of the danger and the means of avoiding it; the other even more reasonable says that it is too painful and harassing to think of the danger, since it is not a man's power to provide for everything and escape from the general march of events; and that it is therefore better to turn aside from the painful subject till it has come, and to think of what is pleasant. In solitude a man generally yields to the first voice; in society to the second.

I have nothing but contempt for you idiotic chosen ones who have the heart to rejoice when there are the damned in Hell and the poor on earth; as for me, I am on the side of men and I will not leave it.

Time is the soul of this world.

With prophecies the commentator is often a more important man than the prophet.

All men cannot receive this saying, save they to whom it is given. For there are some eunuchs, which were so born from their mother's womb: and there are some eunuchs, which were made eunuchs of men: and there be eunuchs, which have made themselves eunuchs for the kingdom of heaven's sake. He that is able to receive it, let him receive it.

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.

And I must speak plainly. If I were a judge, I would have such a poisonous, syphilitic whore tortured by being broken on the wheel and having her veins lacerated, for it is not to be denied what damage such a filthy whore does to young blood, so that it is unspeakably damaged before it is even fully grown and destroyed in the blood.

I take toleration to be a part of religion. I do not know which I would sacrifice; I would keep them both: it is not necessary that I should sacrifice either.

Freedom's possibility is not the ability to choose the good or the evil. The possibility is to be able. In a logical system, it is convenient to say that possibility passes over into actuality. However, in actuality it is not so convenient, and an intermediate term is required. The intermediate term is anxiety, but it no more explains the qualitative leap than it can justify it ethically. Anxiety is neither a category of necessity nor a category of freedom; it is entangled freedom, where freedom is not free in itself but entangled, not by necessity, but in itself.

But the truth is that my work - I was going to say my mission - is to shatter the faith of men here, there, and everywhere, faith in affirmation, faith in negation, and faith in abstention in faith, and this for the sake of faith in faith itself; it is to war against all those who submit, whether it be to Catholicism, or to rationalism, or to agnosticism; it is to make all men live the life of inquietude and passionate desire.

Such then is the human condition, that to wish greatness for one's country is to wish harm to one's neighbors.

The concessions of the weak are the concessions of fear.

There is not a truth existing which I fear or would wish unknown to the whole world.

Skepticism, like chastity, should not be relinquished too readily.

The universal hypocrisy has so entered into the flesh and blood of all classes of our modern society, it has reached such a pitch that nothing in that way can rouse indignation. Hypocrisy in the Greek means "acting," and acting-playing a part-is always possible. Chapter XII, Conclusion-Repent Ye, for the Kingdom of Heaven is at Hand Variant Translation: Hypocrisy with good reason means the same as acting, and anybody can pretend - act a part.

We feel and know that we are eternal.

The strange superstition has arisen in the Western world that we can start all over again, remaking human nature, human society, and the possibilities of happiness; as though the knowledge and experience of our ancestors were now entirely irrelevant.

Heaven, in the production of things, is sure to be bountiful to them, according to their qualities. Hence the tree that is flourishing, it nourishes, while that which is ready to fall, it overthrows.

Within the last fifty years, the extraordinary growth of every department of physical science has spread among us mental food of so nutritious and stimulating a character that a new ecdysis seems imminent.

It is an article of passionate faith among "politically correct" biologists and anthropologists that brain size has no connection with intelligence; that intelligence has nothing to do with genes; and that genes are probably nasty fascist things anyway.

You do not attain to knowledge by remaining on the shore and watching the foaming waves, you must make the venture and cast yourself in, you must swim, alert and with all your force, even if a moment comes when you think you are losing consciousness; in this way, and in no other, do you reach anthropological insight.

The world and the universe is an extremely beautiful place, and the more we understand about it the more beautiful does it appear. It is an immensely exciting experience to be born in the world, born in the universe, and look around you and realise that before you die you have the opportunity of understanding an immense amount about that world and about that universe and about life and about why we're here. We have the opportunity of understanding far, far more than any of our predecessors ever. That is such an exciting possibility, it would be such a shame to blow it and end your life not having understood what there is to understand.

For the philosophy which is so important in each of us is not a technical matter; it is our more or less dumb sense of what life honestly and deeply means. It is only partly got from books; it is our individual way of just seeing and feeling the total push and pressure of the cosmos. ...I have heard friends and colleagues try to popularize philosophy... but they soon grew dry, and then technical, and the results were only partially encouraging. So my enterprise is a bold one. The founder of pragmatism... gave... lectures... with that very word in its title,-flashes of brilliant light relieved against Cimmerian darkness! None of us... understood all that he said-yet here I stand making a very similar venture. ...There is... a curious fascination in hearing deep things talked about, even though neither we nor the disputants understand them. We get the problematic thrill, we feel the presence of the vastness.

Hearken with your ears to these best counsels,Reflect upon them with illumined judgment.Let each one choose his creed with that freedom of choice each must have at great events.

You called and cried out loud and shattered my deafness. You were radiant and resplendent, you put to flight my blindness. You were fragrant, and I drew in my breath and now pant after you. I tasted you, and I feel but hunger and thirst for you. You touched me, and I am set on fire to attain the peace which is yours.

Even when the wound is healed, the scar remains.

Genius is always sufficiently the enemy of genius by over influence.

Inventors and geniuses have almost always been looked on as no better than fools at the beginning of their career, and very frequently at the end of it also.

Tis evident, that sympathy, or the communication of passions, takes place among animals, no less than among men. Fear, anger, courage and other affections are frequently communicated from one animal to another [...] And 'tis remarkable, that tho' almost all animals use in play the same member, and nearly the same action as in fighting; a lion, a tyger, a cat their paws; an ox his homs; a dog his teeth; a horse his heels: Yet they most carefully avoid harming their companion, even tho' they have nothing to fear from his resentment; which is an evident proof of the sense brutes have of each other's pain and pleasure.

Happiest are the people who give most happiness to others.

A great deal of talent is lost to the world for the want of a little courage. Every day sends to their graves a number of obscure men who have only remained obscure because their timidity has prevented them from making a first effort.

Justice does not require that men must stand idly by while others destroy the basis of their existence.

Knowledge is employed in the service of the necessity of life and primarily in the service of the instinct of personal preservation. The necessity and this instinct have created in man the organs of knowledge and given them such capacity as they possess. Man sees, hears, touches, tastes and smells that which it is necessary for him to see, hear, touch, taste and smell in order to preserve his life. The decay or loss of any of these senses increases the risks with which his life is environed, and if it increases them less in the state of society in which we are actually living, the reason is that some see, hear, touch, taste and smell for others. A blind man, by himself and without a guide, could not live long. Society is an additional sense; it is the true common sense.

Honor Wisdom; and deny it not to them that would learn; and shew it unto them that dispraise it! Sow not the sea fields!

Teach him what has been said in the past; then he will set a good example to the children of the magistrates, and judgement and all exactitude shall enter into him. Speak to him, for there is none born wise.

Europeans are awakening more and more to a sense that beasts have rights, in proportion as the strange notion is being gradually overcome and outgrown, that the animal kingdom came into existence solely for the benefit and pleasure of man. This view, with the corollary that non-human living creatures are to be regarded merely as things, is at the root of the rough and altogether reckless treatment of them, which obtains in the West.

The romantic poetry is a progressive universal poetry.

Nietzsche ... did not settle for a demure civic conversation in the style of Richard Rorty's ironist, or saunter off with the smug nod that registers a deconstructive job neatly done. He was aware that his own criticisms and exposures owed both their motivation and their effect to the spirit of truthfulness. His aim was to see how far the values of truth could be revalued, how they might be understood in a perspective quite different from the Platonic and Christian metaphysics which had provided their principal source in the West up to now.

Conservatives believe that our identities and values are formed through our relations with other people, and not through our relation with the state. The state is not an end but a means. Civil society is the end, and the state is the means to protect it. The social world emerges through free association, rooted in friendship and community life. And the customs and institutions that we cherish have grown from below, by the 'invisible hand' of co-operation. They have rarely been imposed from above by the work of politics, the role of which, for a conservative, is to reconcile our many aims, and not to dictate or control them.

Where conscious subjectivity is concerned, there is no distinction between the observation and the thing observed.

Malice sucks up the greatest part of its own venom, and poisons itself.

I have no need to take up each thing that wants to throw its cause on us and show that it is occupied only with itself, not with us, only with its good, not with ours. Look at the rest for yourselves. Do truth, freedom, humanity, justice, desire anything else than that you grow enthusiastic and serve them?

I believe that the advance of science depends upon the free competition of thought, and thus upon freedom, and that it must come to an end if freedom is destroyed (though it may well continue for some time in some fields, especially in technology).

The Chinese are a great nation, incapable of permanent suppression by foreigners. They will not consent to adopt our vices in order to acquire military strength; but they are willing to adopt our virtues in order to advance in wisdom. I think they are the only people in the world who quite genuinely believe that wisdom is more precious than rubies. That is why the West regards them as uncivilized.

It is very important to note that some 2,500 years ago at the least Pythagoras went from Samos to the Ganges to learn geometry...But he would certainly not have undertaken such a strange journey had the reputation of the Brahmins' science not been long established in Europe...
