We shall, therefore, assume the complete physical equivalence of a gravitational field and a corresponding acceleration of the reference system.

See thou tell no man; but go thy way, shew thyself to the priest, and offer the gift that Moses commanded, for a testimony unto them.

Evils draw men together.

What defects women have, we must check them for in private, gently by word of mouth, for woman is a frail vessel.

Confession frees, but power reduces one to silence; truth does not belong to the order of power, but shares an original affinity with freedom: traditional themes in philosophy, which a political history of truth would have to overturn by showing that truth is not by nature free--nor error servile--but that its production is thoroughly imbued with relations of power. The confession is an example of this.

There is not a Musselman alive who would not imagine that he was performing an action pleasing to God and his Holy Prophet by exterminating every Christian on earth, while the Christians are scarcely more tolerant on their side.

Do not commence your exercises in philosophy in those regions where an error can deliver you over to the executioner.

I feel awe of the gods, I love, I revere, I venerate them, and in short have precisely the same feelings towards them as one would have towards kind masters or teachers or fathers or guardians or any beings of that sort.

Bourgeois civilization has built railroads and electric power plants, has invented explosives and airplanes, in order to create wealth. Imperialism has placed the tools of peace in the service of destruction. With modern means it would be easy to wipe out humanity at one blow.

Do not hire a man who does your work for money, but him who does it for love of it.

Everyone has a religion, whether admitted or not, because it is impossible to be human without having some basic assumptions (or intuitions) about existence and the good life.

Given our anthropocentric bias, thinking of non-human vertebrates not just as equivalent in moral status to toddlers or infants, but as though they were toddlers or infants, is a useful exercise. Such reconceptualisation helps correct our lack of empathy for sentient beings whose physical appearance is different from "us". Ethically, the practice of intelligent "anthropomorphism" shouldn't be shunned as unscientific, but embraced insofar as it augments our stunted capacity for empathy. Such anthropomorphism can be a valuable corrective to our cognitive and moral limitations. This is not a plea to be sentimental, simply for impartial benevolence.

A good traveler is one who does not know where he is going to, and a perfect traveler does not know where he came from.

To sum up: it is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence. If a man, holding a belief which he was taught in childhood or persuaded of afterwards, keeps down and pushes away any doubts which arise about it in his mind, purposely avoids the reading of books and the company of men that call into question or discuss it, and regards as impious those questions which cannot easily be asked without disturbing it--the life of that man is one long sin against mankind.

Nature, therefore, is subject with absolute precision to all the precepts of geometry as to all the properties of space there demonstrated, this being the subjective condition, not hypothetically but intuitively given, of every phenomenon in which nature can ever be revealed to the senses.

To explain the origin of the DNA/protein machine by invoking a supernatural Designer is to explain precisely nothing, for it leaves unexplained the origin of the Designer.

As one digs deeper into the national character of the Americans, one sees that they have sought the value of everything in this world only in the answer to this single question: how much money will it bring in?

In ease of body and peace of mind, all the different ranks of life are nearly upon a level, and the beggar, who suns himself by the side of the highway, possesses that security which kings are fighting for.

Praise be to God with all due praise, and a prayer for Muhammad His chosen servant and apostle. The purpose of this treatise is to examine, from the standpoint of the study of the Law, whether the study of philosophy and logic is allowed by the Law, or prohibited, or commanded either by way of recommendation or as obligatory.

As if our birth had at first sundered things, and we had been thrust up through into nature like a wedge, and not till the wound heals and the scar disappears, do we begin to discover where we are, and that nature is one and continuous everywhere.

God is the solitude of men. There was only me: I alone decided to commit Evil; alone, I invented Good. I am the one who cheated, I am the one who performed miracles, I am the one accusing myself today, I alone can absolve myself; me, the man.

There is no need to worry about mere size. We do not necessarily respect a fat man more than a thin man. Sir Isaac Newton was very much smaller than a hippopotamus, but we do not on that account value him less.

The word of man is the most durable of all material.

I want death to find me planting my cabbages.

The belief that there is some hidden cabal directing the course of events is a type of anthropomorphism - a way of finding agency in the entropy of history.

A trifling debt makes a man your debtor; a large one makes him an enemy.

And finally remember that nothing harms him who is really a citizen, which does not harm the state; nor yet does anything harm the state which does not harm law [order]; and of these things which are called misfortunes not one harms law. What then does not harm law does not harm either state or citizen.

He who boasts of his descent, praises the deeds of another.

It is better to correct your own faults than those of another.

Death, they say, acquits us of all obligations.

The best work is not what is most difficult for you; it is what you do best.

In ancient Europe, Stoics asserted that a slave could be freer than a master who suffers from self-division. In China, Daoists imagined a type of sage who responded to the flow of events without weighing alternatives. Disciples of monotheistic faiths have believed something similar: freedom, they say, is obeying God's will. What those who follow these traditions want most is not any kind of freedom of choice. Instead, what they long for is freedom from choice.

Let what will be said or done, preserve your sang-froid immovably, and to every obstacle, oppose patience, perseverance, and soothing language.

To work and create "for nothing," to sculpture in clay, to know one's creation has no future, to see one's work destroyed in a day while being aware that fundamentally this has no more importance than building for centuries, this is the difficult wisdom that absurd thought sanctions. Performing these two tasks simultaneously, negating on the one hand and magnifying on the other, it the way open to the absurd creator. He must give the void its colors.

Fortunately science, like that nature to which it belongs, is neither limited by time nor by space. It belongs to the world, and is of no country and of no age. The more we know, the more we feel our ignorance; the more we feel how much remains unknown; and in philosophy, the sentiment of the Macedonian hero can never apply, - there are always new worlds to conquer.

Neither did the dispensation of God vary in the times after our Saviour came into the world; for our Saviour himself did first show His power to subdue ignorance, by His conference with the priests and doctors of the law, before He showed His power to subdue nature by His miracles. And the coming of this Holy Spirit was chiefly figured and expressed in the similitude and gift of tongues, which are but vehicula scientiæ.

It is impossible for any man, when the most favourable circumstances concur, to acquire sufficient knowledge and strength of mind to discharge the duties of a king, entrusted with uncontrolled power; how then must they be violated when his very elevation is an insuperable bar to the attainment of either wisdom or virtue; when all the feelings of a man are stifled by flattery, and reflection shut out by pleasure! Surely it is madness to make the fate of thousands depend on the caprice of a weak fellow creature, whose very station sinks him NECESSARILY below the meanest of his subjects! But one power should not be thrown down to exalt another--for all power intoxicates weak man; and its abuse proves, that the more equality there is established among men, the more virtue and happiness will reign in society.

Beauty is merciless. You do not look at it, it looks at you and does not forgive.

We boil at different degrees.

We are obviously heading for revolution-something I have never once doubted since 1850. The first act will include a by no means gratifying rehash of the stupidities of '48-'49. However, that's how world history runs its course, and one has to take it as one finds it.

More is given to us than to any people at any time before; and, therefore, more is required of us. We have made, and still are making, enormous advances on material lines. It is necessary that we commensurately advance on moral lines. Civilization, as it progresses, requires a higher conscience, a keener sense of justice, a warmer brotherhood, a wider, loftier, truer public spirit. Falling these, civilization must pass into destruction. It cannot be maintained on the ethics of savagery. For civilization knits men more and more closely together, and constantly tends to subordinate the individual to the whole, and to make more and more important social conditions.

He tried to recall what he had read about the disease. Figures floated across his memory, and he recalled that some thirty or so great plagues known to history had accounted for nearly a hundred million deaths. But what are a hundred million deaths? When one has served in a war, one hardly knows what a dead man is, after a while. And since a dead man has no substance unless one actually sees him dead, a hundred million corpses broadcast through history are no more than a puff of smoke in the imagination.

I am looking forward very much to getting back to Cambridge, and being able to say what I think and not to mean what I say: two things which at home are impossible. Cambridge is one of the few places where one can talk unlimited nonsense and generalities without anyone pulling one up or confronting one with them when one says just the opposite the next day.

Mahomet established a religion by putting his enemies to death; Jesus Christ, by commanding his followers to lay down their own lives.

Liberty, as we all know, cannot flourish in a country that is permanently on a war footing, or even a near war footing. Permanent crisis justifies permanent control of everybody and everything by the agencies of central government.
