He maintained this attitude up to the very end, and no man ever saw Socrates too much elated or too much depressed. Amid all the disturbance of Fortune, he was undisturbed.

If space in infinite, how about the space inside man? Blake said that eternity opens from the center of an atom. My former terror vanished. Now I saw that I was mistaken in thinking of myself as an object in a dead landscape. I had been assuming that man is limited because his brain is limited, that only so much can be packed into the portmanteau. But the spaces of the mind are a new dimension. The body is a mere wall between two infinities. Space extends to infinity outwards; the mind stretches to infinity inwards.

Friends, the soil is poor, we must sow seeds in plenty for us to garner even modest harvests.

The man of perfect virtue is cautious and slow in his speech. When a man feels the difficulty of doing, can he be other than cautious and slow in speaking?

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.

There are no signposts in the sky to show a man has passed that way before. There are no channels marked. The flier breaks each second into new uncharted seas.

Credulity in arts and opinions is likewise of two kinds viz., when men give too much belief to arts themselves, or to certain authors in any art. The sciences that sway the imagination more than the reason are principally three viz., astrology, natural magic, and alchemy. Alchemy may be compared to the man who told his sons that he had left them gold, buried somewhere in his vineyard; while they by digging found no gold, but by turning up the mould about the roots of the vines procured a plentiful vintage. So the search and endeavours to make gold have brought many useful inventions to light.

I understand the task of sociology to be description and determination of the historical-psychological origin of those forms in which interactions take place between human beings. The totality of these interactions, springing from the most diverse impulses, directed toward the most diverse objects, and aiming at the most diverse ends, constitutes "society."

Superstition sets the whole world in flames; philosophy quenches them.

No one should be judge in his own cause.

Sleep is a death; oh, make me try By sleeping what it is to die, And as gently lay my head On my grave as now my bed.

A fire eater must eat fire even if he has to kindle it himself.

There is merely bad luck in not being loved; there is misfortune in not loving. All of us, today, are dying of this misfortune. For violence and hatred dry up the heart itself; the long fight for justice exhausts the love that nevertheless gave birth to it.

The Being of the universe, at first hidden and concealed, has no power which can offer resistance to the search for knowledge ; it has to lay itself open before the seeker - to set before his eyes and give for his enjoyment, its riches and its depths.

Every hero becomes a bore at last.

The battling Reformer too is, from time to time, a needful and inevitable phenomenon. Obstructions are never wanting: the very things that were once indispensable furtherances become obstructions; and need to be shaken off, and left behind us,-a business often of enormous difficulty.

In so far as words are not used obviously to calculate technically relevant probabilities or for other practical purposes, ... they are in danger of being suspect as sales talk of some kind.

Death is not an event in life: we do not live to experience death. If we take eternity to mean not infinite temporal duration but timelessness, then eternal life belongs to those who live in the present. Our life has no end in just the way in which our visual field has no limits.

Whatsoever any man either doth or saith, thou must be good; not for any man's sake, but for thine own nature's sake; as if either gold, or the emerald, or purple, should ever be saying to themselves, Whatsoever any man either doth or saith, I must still be an emerald, and I must keep my colour.

It is sad not to be loved, but it is much sadder not to be able to love.

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.

I regard religion as a disease born of fear and as a source of untold misery to the human race.

Judge not, that ye be not judged. For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again.

We have all experienced the moments that William James calls melting moods, when it suddenly becomes perfectly obvious that life is infinitely fascinating. And the insight seems to apply retrospectively. Periods of my life that seemed confusing and dull at the time now seem complex and rather charming. It is almost as if some other person a more powerful and mature individual has taken over my brain. This higher self views my problems and anxieties with kindly detachment, but entirely without pity. Looking at problems through his eyes, I can see I was a fool to worry about them.

An expert is a person who has found out by his own painful experience all the mistakes that one can make in a very narrow field.

The poor man is ruined as soon as he begins to ape the rich.

Whether directly or indirectly all nations are originally nothing but Indian colonies... the oriental antiquity could, if we consented to deepen it, bring us back more safely towards the divine....

In the beginning there were two primal spirits,Twins spontaneously active,These are the Good and the Evil, in thought, and in word, and in deed.

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.

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

Self-preservation has frequently knuckled under to that tremendous yearning to get even.

Intolerance is the besetting sin of moral fervour.

I assert, that the ancient Whigs held doctrines, totally different from those I have last mentioned. I assert, that the foundations laid down by the Commons, on the trial of Doctor Sacheverel, for justifying the revolution of 1688, are the very same laid down in Mr. Burke's Reflections; that is to say,-a breach of the original contract, implied and expressed in the constitution of this country, as a scheme of government fundamentally and inviolably fixed in King, Lords, and Commons.-That the fundamental subversion of this antient constitution, by one of its parts, having been attempted, and in effect accomplished, justified the Revolution. That it was justified only upon the necessity of the case; as the only means left for the recovery of that antient constitution, formed by the original contract of the British state; as well as for the future preservation of the same government. These are, the points to be proved.

Love is a God, who cooperates in securing the safety of the city.

How can a man be said to have a country where he has no right to a square inch of soil...

A little of all things, but nothing of everything, after the French manner.

Whatever happens, I cannot be a silent witness to murder or torture. Anyone who is a partner in this is a despicable individual. I am sorry I cannot be moderate about it...

Placing your stick at the end of the shadow of the pyramid, you made by the sun's rays two triangles, and so proved that the pyramid [height] was to the stick [height] as the shadow of the pyramid to the shadow of the stick.

No matter how outrageous a lie may be, it will be accepted if stated loudly enough and often enough.

But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.

The Managers of that Trade themselves, and others, testify, that many of these African nations inhabit fertile countries, are industrious farmers, enjoy plenty, and lived quietly, averse to war, before the Europeans debauched them with liquors, and bribing them against one another; and that these inoffensive people are brought into slavery, by stealing them, tempting Kings to sell subjects, which they can have no right to do, and hiring one tribe to war against another, in order to catch prisoners. By such wicked and inhuman ways the English are said to enslave towards one hundred thousand yearly; of which thirty thousand are supposed to die by barbarous treatment in the first year; besides all that are slain in the unnatural wars excited to take them. So much innocent blood have the Managers and Supporters of this inhuman Trade to answer for to the common Lord of all!

As the Swiss inscription says: Sprechen ist silbern, Schweigen ist golden- "Speech is silvern, Silence is golden"; or, as I might rather express it: speech is of time, silence is of eternity.

I never turned recreant to intellectual culture, or ceased to consider the power and practice of analysis as an essential condition both of individual and of social improvement. But I thought that it had consequences which required to be corrected, by joining other kinds of cultivation with it. The maintenance of a due balance among the faculties, now seemed to me of primary importance. The cultivation of the feelings became one of the cardinal points in my ethical and philosophical creed.

We are, I know not how, double in ourselves, which is the cause that what we believe we do not believe, and cannot disengage ourselves from what we condemn.

What is the case, the fact, is the existence of atomic facts.

The only purpose for which power can be rightfully exercised over any member of a civilized community, against his will, is to prevent harm to others. His own good, either physical or moral, is not a sufficient warrant.

When I started life Hegelianism was the basis of everything: it was in the air, found expression in magazine and newspaper articles, in novels and essays, in art, in histories, in sermons, and in conversation. A man unacquainted with Hegel had no right to speak: he who wished to know the truth studied Hegel. Everything rested on him; and suddenly forty years have gone by and there is nothing left of him, he is not even mentioned - as though he had never existed. And what is most remarkable is that, like pseudo-Christianity, Hegelianism fell not because anyone refuted it, but because it suddenly became evident that neither the one nor the other was needed by our learned, educated world.

Perhaps some day soon we will have arrived at the point when we can look back with irony at the barbaric old times when in order to be free we had to keep our own brothers and sisters slaves or to be equal we were constrained to inhuman sacrifices of freedom.

Erudition can produce foliage without bearing fruit.
