A lively and lasting sense of filial duty is more effectually impressed on the mind of a son or daughter by reading King Lear, than by all the dry volumes of ethics, and divinity, that ever were written.

To shoot down a European is to kill two birds with one stone, to destroy an oppressor and the man he oppresses at the same time.

It really comes down to parsimony, economy of explanation. It is possible that your car engine is driven by psychokinetic energy, but if it looks like a petrol engine, smells like a petrol engine and performs exactly as well as a petrol engine, the sensible working hypothesis is that it is a petrol engine.

The new tinge to modern minds is a vehement and passionate interest in the relation of general principles to irreducible and stubborn facts. All the world over and at all times there have been practical men, absorbed in 'irreducible and stubborn facts'; all the world over and at all times there have been men of philosophic temperament, who have been absorbed in the weaving of general principles. It is this union of passionate interest in the detailed facts with equal devotion to abstract generalisation which forms the novelty of our present society.

I think that the principal and most basic spiritual need of the Russian People is the need for suffering, incessant and unslakeable suffering, everywhere and in everything. I think the Russian People have been infused with this need to suffer from time immemorial. A current of martyrdom runs through their entire history, and it flows not only from external misfortunes and disasters but springs from the very heart of the People themselves. There is always an element of suffering even in the happiness of the Russian People, and without it their happiness is incomplete.

All that we call human history-money, poverty, ambition, war, prostitution, classes, empires, slavery-the long terrible story of man trying to find something other than God which will make him happy.

Those who give and those who receive arbitrary power are alike criminal; and there is no man but is bound to resist it to the best of his power, wherever it shall show its face to the world. It is a crime to bear it, when it can be rationally shaken off. Nothing but absolute impotence can justify men in not resisting it to the utmost of their ability.

To pray to God is to flatter oneself that with words one can alter nature.

To prove cannot mean anything other than to bring the other person to my own conviction. The truth lies only in the unification of "I" and "You." The Other of pure thought, however, is the sensuous intellect in general. In the field of philosophy, proof therefore consists only in the fact that the contradiction between sensuous intellect and pure thought is disposed, so that thought is true not only for itself but also for its opposite.

Truth and falsity are the most fundamental terms of rational criticism, and any adequate philosophy must give some account of these, or failing that, show that they can be dispensed with.

It may seem to be a long way from Blake's innocent talk of love and copulation to De Sade's need to inflict pain. And yet both are the outcome of a sexual mysticism that strives to transcend the everyday world. Simone de Beauvoir said penetratingly of De Sade's work that 'he is trying to communicate an experience whose distinguishing characteristic is, nevertheless its will to remain incommunicable'. De Sade's perversion may have sprung from his dislike of his mother or of other women, but its basis is a kind of distorted religious emotion.

Morality is thus the relation of actions to the autonomy of the will, that is, to a possible giving of universal law through its maxims. An action that can coexist with the autonomy of the will is permitted; one that does not accord with it is forbidden. A will whose maxims necessarily harmonize with the laws of autonomy is a holy, absolutely good will. The dependence upon the principle of autonomy of a will that is not absolutely good (moral necessitation) is obligation. This, accordingly, cannot be attributed to a holy being. The objective of an action from obligation is called duty.

"If a nation expects to be ignorant and free," said Jefferson, "it expects what never was and never will be."

I could never divide myself from any man upon the difference of an opinion, or be angry with his judgement for not agreeing with me in that, from which perhaps within a few days I should dissent myself.

Science is meaningless because it gives no answer to our question, the only question important for us: 'what shall we do and how shall we live.

If the present Congress errs in too much talking, how can it be otherwise in a body to which the people send 150 lawyers, whose trade it is to question everything, yield nothing, and to talk by the hour?

And see, a kind, refined lady will devour the carcasses of these animals with full assurance that she is doing right, at the same time asserting two contradictory propositions: First, that she is, as her doctor assures her, so delicate that she cannot be sustained by vegetable food alone, and that for her feeble organism flesh is indispensable; and, secondly, that she is so sensitive that she is unable, not only herself to inflict suffering on animals, but even to bear the sight of suffering. Whereas the poor lady is weak precisely because she has been taught to live upon food unnatural to man; and she cannot avoid causing suffering to animals - for she eats them.

Burns's Brother Gilbert, a man of much sense and worth, has told me that Robert, in his young days, in spite of their hardship, was usually the gayest of speech; a fellow of infinite frolic, laughter, sense and heart; far pleasanter to hear there, stript cutting peats in the bog, or such like, than he ever afterwards knew him. I can well believe it. This basis of mirth, a primal element of sunshine and joyfulness, coupled with his other deep and earnest qualities, is one of the most attractive characteristics of Burns. A large fund of Hope dwells in him; spite of his tragical history, he is not a mourning man. He shakes his sorrows gallantly aside; bounds forth victorious over them.

Society ... can afford to grant more than before because its interests have become the innermost drives of its citizens.

All savageness is a sign of weakness.

A harmonious being cannot believe in God. Saints, criminals, and paupers have launched him, making him available to all unhappy people.

Of the various executive abilities, no one excited more anxious concern than that of placing the interests of our fellow-citizens in the hands of honest men, with understanding sufficient for their stations. No duty is at the same time more difficult to fulfil. The knowledge of character possessed by a single individual is of necessity limited. To seek out the best through the whole Union, we must resort to the information which from the best of men, acting disinterestedly and with the purest motives, is sometimes incorrect.

A slight sound at evening lifts me up by the ears, and makes life seem inexpressibly serene and grand. It may be Uranus, or it may be in the shutter.

From an ill-natured man take no loan.

If you press me to say why I loved him, I can say no more than it was because he was he, and I was I. Variants: If a man urge me to tell wherefore I loved him, I feel it cannot be expressed but by answering: Because it was he, because it was myself. If a man should importune me to give a reason why I loved him, I find it could no otherwise be expressed, than by making answer: because it was he, because it was I.

A marvel that has nothing to offer, democracy is at once a nation's paradise and its tomb.

What is to prevent one from telling truth as he laughs, even as teachers sometimes give cookies to children to coax them into learning their A B C?

There is no one who ever acts honestly in the administration of states, nor any helper who will save any one who maintains the cause of the just.

A free people claim their rights, as derived from the laws of nature, and not as the gift of their chief magistrate.

Merit is a work for the sake of which Christ gives rewards. But no such work is to be found, for Christ gives by promise. Just as if a prince should say to me, "Come to me in my castle, and I will give you a hundred florins." I do a work, certainly, in going to the castle, but the gift is not given me as the reward of my work in going, but because the prince promised it to me.

Life is bristling with thorns, and I know no other remedy than to cultivate one's garden.

One day, we shall stand up and our backsides will remain attached to our seats.

The subversive character of truth inflicts upon thought an imperative quality. Logic centers on judgments which are, as demonstrative propositions, imperatives, - the predicative "is" implies an "ought." ... Verification of the proposition involves a process in fact as well as in thought: (S) must become that which it is. The categorical statement thus turns into a categorical imperative; it does not state a fact but the necessity to bring about a fact. For example, it could be read as follows: man is not (in fact) free, endowed with inalienable rights, etc., but he ought to be.

An art that heals and protects its subject is a geography of scars.

A man cannot become a child again, or he becomes childish.

It was his peculiar doctrine that a man has a perfect right to interfere by force with the slaveholder, in order to rescue the slave. I agree with him. They who are continually shocked by slavery have some right to be shocked by the violent death of the slaveholder, but no others.

Two difficulties: (1) Can we transform psychologic time, which is qualitative, into a quantitative time? (2) Can we reduce to one and the same measure facts which transpire in different worlds [of conscious beings]!

Heroism feels and never reasons and therefore is always right.

State and government are the social apparatus of violent coercion and repression. Such an apparatus, the police power, is indispensable in order to prevent anti-social individuals and bands from destroying social co-operation. Violent prevention and suppression of anti-social activities benefit the whole of society and each of its members. But violence and oppression are none the less evils and corrupt those in charge of their application. It is necessary to restrict the power of those in office lest they become absolute despots. Society cannot exist without an apparatus of violent coercion. But neither can it exist if the office holders are irresponsible tyrants free to inflict harm upon those they dislike.

It is therefore, the interest of all, that every one, from birth, should be well educated, physically and mentally, that society may be improved in its character, - that everyone should be beneficially employed, physically and mentally, that the greatest amount of wealth may be created, and knowledge attained, - that everyone should be placed in the midst of those external circumstances that will produce the greatest number of pleasurable sensations, through the longest life, that man may be made truly intelligent, moral and happy, and be thus prepared to enter upon the coming Millennium.

I see that sensible men and conscientious men all over the world were of one religion.

We came to a tree which was still bare, and on which the birds were singing out gaily in the morning, without any fear of us. Then stooping over like an Indian on the hunt, my companion placed a pebble in the leather of his sling and stretched it. Obeying his peremptory glance I did the same, with frightful twinges of conscience, vowing firmly that I would shoot when he did. At that very moment the church bells began to sound, mingling with the song of the birds in the sunshine. It was the warning bell that came a half-hour before the main bell. For me it was a voice from heaven. I threw the sling down, scaring the birds away, so that they were safe from my companion's sling, and fled home. And ever afterwards when the bells of Holy Week ring out amidst the leafless trees in the sunshine I remember with moving gratitude how they rang into my heart at that time the commandment: Thou shalt not kill.

Men will not understand ... that when they fulfil their duties to men, they fulfil thereby God's commandments; that they are consequently always in the service of God, as long as their actions are moral, and that it is absolutely impossible to serve God otherwise.
