We may assume the existence of an aether; only we must give up ascribing a definite state of motion to it, i.e. we must by abstraction take from it the last mechanical characteristic which Lorentz had still left it. ... But this ether may not be thought of as endowed with the quality characteristic of ponderable media, as consisting of parts which may be tracked through time. The idea of motion may not be applied to it.

They indicate the saddest spiritual paralysis, and mere death-life of the souls of men: more godless theory, I think, was never promulgated in this Earth. A false man found a religion? Why, a false man cannot build a brick house!

God is not needed to create guilt or to punish. Our fellow men suffice, aided by ourselves.

Those of our pleasures which come most rarely give the greatest delight.

The most strongly enforced of all known taboos is the taboo against knowing who or what you really are behind the mask of your apparently separate, independent, and isolated ego.

I might try to save the view that 'future contingents' have no truth value by saying that even present-tense statements have no truth value if they refer to the outcome of events that are so far away that a causal signal informing me of the outcome could not have reached me-now without traveling faster than light. In other words, I might attempt saying that statements about events that are in neither the upper half nor the lower half of my light-cone have no truth value. In addition, statements about events in the upper half of my light-cone have no truth value, since they are in my future according to every coordinate system. So only statements about events in the lower half of my light-cone have a truth value; only events that are in 'my past* according to all observers are determined.

The value which the workmen add to the materials, therefore, resolves itself in this case into two parts, of which the one pays their wages, the other the profits of the employer upon the whole stock of materials and wages which he advanced.

All that the conscious ego can do is to formulate wishes, which are then carried out by forces which it controls very little and understands not at all.

The woman who fights against her father still has the possibility of leading an instinctive, feminine existence, because she rejects only what is alien to her. But when she fights against the mother she may, at the risk of injury to her instincts, attain to greater consciousness, because in repudiating the mother she repudiates all that is obscure, instinctive, ambiguous, and unconscious in her own nature.

We return to our analysis of qualities. Something preserves itself throughout this flux, something that passes into other things, but also stands against them as a being for itself. This something can exist only as the product of a process through which it integrates its otherness with its own proper being. Hegel says that its existence comes about through 'the negation of the negation.' The first negation is the otherness in which it turns, and the second is the incorporation of this other into its own self. Such a process presupposes that things possess a certain power over their movement, that they exist in a certain self-relation that enables them to 'mediate' their existential conditions.

Anger is a weed; hate is the tree.

The new order contradicts reason so fundamentally that reason does not dare to doubt it. Even the consciousness of oppression fades. The more incommensurate become the concentration of power and the helplessness of the individual, the more difficult for him to penetrate the human origin of his misery.

Important though the general concepts and propositions may be with which the modern industrious passion for axiomatizing and generalizing has presented us, in algebra perhaps more than anywhere else, nevertheless I am convinced that the special problems in all their complexity constitute the stock and core of mathematics; and to master their difficulties requires on the whole the harder labor.

Attention consists of suspending our thought, leaving it detached, empty, and ready to be penetrated by the object; it means holding in our minds, within reach of this thought, but on a lower level and not in contact with it, the diverse knowledge we have acquired which we are forced to make use of.

Nature paints the best part of a picture, carves the best parts of the statue, builds the best part of the house, and speaks the best part of the oration.

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.

Live always in the best company when you read.

No man is liberated from fear who dare not see his place in the world as it is; no man can achieve the greatness of which he is capable until he has allowed himself to see his own littleness.

Ancient histories, as one of our wits has said, are but fables that have been agreed upon.

Rights are, then, the fruits of the law, and of the law alone. There are no rights without law-no rights contrary to the law-no rights anterior to the law. Before the existence of laws there may be reasons for wishing that there were laws-and doubtless such reasons cannot be wanting, and those of the strongest kind;-but a reason for wishing that we possessed a right, does not constitute a right. To confound the existence of a reason for wishing that we possessed a right, with the existence of the right itself, is to confound the existence of a want with the means of relieving it. It is the same as if one should say, everybody is subject to hunger, therefore everybody has something to eat.

I have seen something of the project of M. de St. Pierre, for maintaining a perpetual peace in Europe. I am reminded of a device in a cemetery, with the words: Pax perpetua; for the dead do not fight any longer: but the living are of another humor; and the most powerful do not respect tribunals at all. 

How old the world is! I walk between two eternities... What is my fleeting existence in comparison with that decaying rock, that valley digging its channel ever deeper, that forest that is tottering and those great masses above my head about to fall? I see the marble of tombs crumbling into dust; and yet I don't want to die!

The death clock is ticking slowly in our breast, and each drop of blood measures its time, and our life is a lingering fever.

Who dismisses his adulterous wife and marries another woman, whereas his first wife still lives, remains perpetually in the state of adultery. Such a man does not any efficacious penance while he refuses to abandon the new wife. If he is a catechumen, he cannot be admitted to baptism, because his will remains rooted in the evil. If he is a (baptized) penitent, he cannot receive the (ecclesiastical) reconciliation as long as he does not break with his bad attitude.

Very little is needed to make a happy life.

Remember that the term Rational was intended to signify a discriminating attention to every several thing and freedom from negligence; and that Equanimity is the voluntary acceptance of things which are assigned to thee by the common nature; and the Magnanimity is the elevation of the intelligent part above the pleasurable or painful sensations of the flesh, and above that poor thing called fame, and death, and all such things. If then, thou maintainest thyself in the possession of these names, without desiring to be called by these names by others, thou wilt be another person and wilt enter into another life.

There is a real, living unity in our time, as in any other, but it lies submerged under a superficial hubbub of sensation.

Because energy is not restrained by other elements that are at once antagonistic and cooperative, action proceeds by jerks and spasms. There is discontinuity.

The kind of equality utilitarianism supports is given by Bentham's formula...: 'everybody to count for one, and nobody for more than one'...Utilitarianism seeks to maximize happiness, and in deciding how to calculate whether happiness is being maximized, no one's pleasures or pains should count for less because they are peasants rather than aristocrats, slaves rather than slave-owners, Africans rather than Europeans, poor rather than rich, illiterates rather than doctors of philosophy, children rather than adults, females rather than males, or even, as we have seen, non-human animals rather than human beings.

What is that one crucifixion compared to the daily kind any insomniac endures?

I am to talk about Apologetics. Apologetics means of course Defence. The first question is - what do you propose to defend? Christianity, of course...

To confuse our own constructions and inventions with eternal laws or divine decrees is one of the most fatal delusions of men. 

The wise will determine from the gravity of the case; the irritable from sensibility to oppression; the high-minded from disdain and indignation at abusive power in unworthy hands.

The history of the American kings of capital and authority is the history of repeated crimes, injustice, oppression, outrage, and abuse, all aiming at the suppression of individual liberties and the exploitation of the people. A vast country, rich enough to supply all her children with all possible comforts, and insure well-being to all, is in the hands of a few, while the nameless millions are at the mercy of ruthless wealth gatherers, unscrupulous lawmakers, and corrupt politicians.The reign of these kings is holding mankind in slavery, perpetuating poverty and disease, maintaining crime and corruption; it is fettering the spirit of liberty, throttling the voice of justice, and degrading and oppressing humanity. It is engaged in continual war and slaughter, devastating the country and destroying the best and finest qualities of man; it nurtures superstition and ignorance, sows prejudice and strife, and turns the human family into a camp of Ishmaelites.

When people laughed at him because he walked backward beneath the portico, he said to them: "Aren't you ashamed, you who walk backward along the whole path of existence, and blame me for walking backward along the path of the promenade?"

It is not because men's desires are strong that they act ill; it is because their consciences are weak.

I don't understand how people can believe in God, even when I myself think of him everyday.

My life - I had lived in its heights and its depths, in bitter sorrow and ecstatic joy, in black despair and fervent hope. I had drunk the cup to the last drop. I had lived my life. Would I had the gift to paint the life I had lived!

Dreams are the touchstones of our characters.

In argument about moral problems, relativism is the first refuge of the scoundrel.

No one is so modest as not to believe himself a competent amateur sleuth.

The perception of the comic is a tie of sympathy with other men, a pledge of sanity, and protection from those perverse tendencies and gloomy insanities in which fine intellects sometimes lose themselves. A rogue alive to the ludicrous is still convertible.

The assertion that art may be good art and at the same time incomprehensible to a great number of people is extremely unjust, and its consequences are ruinous to art itself...it is the same as saying some kind of food is good but most people can't eat it.

Covetousness, and the desire of having in our possession, and under our dominion, more than we have need of, being the root of all evil, should be early and carefully weeded out, and the contrary quality of a readiness to impart to others, implanted. This should be encourag'd by great commendation and credit, and constantly taking care that he loses nothing by his liberality.

Sincerity becomes apparent. From being apparent, it becomes manifest. From being manifest, it becomes brilliant. Brilliant, it affects others. Affecting others, they are changed by it. Changed by it, they are transformed. It is only he who is possessed of the most complete sincerity that can exist under heaven, who can transform.

The concept of guilt is found most powerfully developed even in the most primitive communal forms which we know: ... the man is guilty who violates one of the original laws which dominate the society and which are mostly derived from a divine founder; the boy who is accepted into the tribal community and learns its laws, which bind him thenceforth, learns to promise; this promise is often given under the sign of death, which is symbolically carried out on the boy, with a symbolical rebirth.

Whatever can be done another day can be done today.

I do see one large and grievous kind of ignorance, separate from the rest, and as weighty as all the other parts put together. Thinking that one knows a thing when one does not know it. Through this, I believe, all the mistakes of the mind are caused in all of us.

If compelled to indicate my religion on an immigration blank, I might be tempted to put down the word "Taoist," to the amazement of the customs officer who probably never heard of it.
