Suppose atomic bombs had reduced the population of the world to one brother and one sister, should they let the human race die out? I do not know the answer, but I do not think it can be in the affirmative merely on the ground that incest is wicked.

Burden not the back of Aries, Leo, or Taurus, with thy faults, nor make Saturn, Mars, or Venus, guilty of thy Follies.

I accept nothing on authority. A hypothesis must be backed by reason, or else it is worthless.

If I hear the Way [of truth] in the morning, I am content even to die in that evening.

Even the free importation of foreign corn could very little affect the interest of the farmers of Great Britain. Corn is a much more bulky commodity than butcher's-meat. A pound of wheat at a penny is as dear as a pound of butcher's-meat at fourpence. The small quantity of foreign corn imported even in times of the greatest scarcity, may satisfy our farmers that they can have nothing to fear from the freest importation.

But the Jews are so hardened that they listen to nothing; though overcome by testimonies they yield not an inch. It is a pernicious race, oppressing all men by their usury and rapine. If they give a prince or magistrate a thousand florins, they extort twenty thousand from the subjects in payment. We must ever keep on guard against them.

Since the law is good, the will, which is hostile to it, cannot be good.

All sentiment is right; because sentiment has a reference to nothing beyond itself, and is always real, wherever a man is conscious of it. But all determinations of the understanding are not right; because they have a reference to something beyond themselves, to wit, real matter of fact; and are not always conformable to that standard.

In fact we do not know anything infallibly, but only that which changes according to the condition of our body and of the [influences] that reach and impinge upon it.

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.

That the sun will not rise to-morrow is no less intelligible a proposition, and implies no contradiction, than the affirmation, that it will rise.

It would be worth the while to look closely into the eye which has been open and seeing at such hours, and in such solitudes, its dull, yellowish, greenish eye. Methinks my own soul must be a bright invisible green.

Patriotism, when it wants to make itself felt in the domain of learning, is a dirty fellow who should be thrown out of doors.

According to Christian teachers, the essential vice, the utmost evil, is Pride. Unchastity, anger, greed, drunkenness, and all that, are mere fleabites in comparison: it was through Pride that the devil became the devil: Pride leads to every other vice: it is the complete anti-God state of mind.

Some men are born committed to action: they do not have a choice, they have been thrown on a path, at the end of that path, an act awaits them, their act.

When we have intelligence resulting from sincerity, this condition is to be ascribed to nature; when we have sincerity resulting from intelligence, this condition is to be ascribed to instruction. But given the sincerity, and there shall be the intelligence; given the intelligence, and there shall be the sincerity.

I deny that anyone knows, or can know, the nature of the two sexes, as long as they have only been seen in their present relation to one another. If men had ever been found in society without women, or women without men, or if there had been a society of men and women in which the women were not under the control of the men, something might have been positively known about the mental and moral differences which may be inherent in the nature of each. What is now called the nature of women is an eminently artificial thing - the result of forced repression in some directions, unnatural stimulation in others.

It is the dissimilarities and inequalities among men which give rise to the notion of honor; as such differences become less, it grows feeble; and when they disappear, it will vanish too.

The universal and lasting establishment of peace constitutes not merely a part, but the whole final purpose and end of the science of right as viewed within the limits of reason.

Cure the drunkard, heal the insane, mollify the homicide, civilize the Pawnee, but what lessons can be devised for the debaucher of sentiment?

Themistocles being asked whether he would rather be Achilles or Homer, said, "Which would you rather be,-a conqueror in the Olympic games, or the crier that proclaims who are conquerors?"

Everyone is entitled to commit murder in the imagination once in a while, not to mention lesser infractions.

The place of the father in the modern suburban family is a very small one - particularly if he plays golf, which he usually does.

Custom, then, is the great guide of human life. It is that principle alone which renders our experience useful to us, and makes us expect, for the future, a similar train of events with those which have appeared in the past. Without the influence of custom, we should be entirely ignorant of every matter of fact beyond what is immediately present to the memory and senses. We should never know how to adjust means to ends, or to employ our natural powers in the production of any effect. There would be an end at once of all action, as well as of the chief part of speculation. Variant (perhaps a paraphrase of this passage): It is not reason which is the guide of life, but custom.

A penny saved is of more value than a penny paid out.

So that it will be found that the fundamental fault in the character of women is that they have no "sense of justice ." This arises from their deficiency in the power of reasoning already referred to, and reflection, but is also partly due to the fact that Nature has not destined them, as the weaker sex, to be dependent on strength but on cunning; this is why they are instinctively crafty, and have an ineradicable tendency to lie.

If the inner psychic ground of our individual appearance were not always the same, there could be no science of psychology, which qua science relies on a psychic "inside we are all alike," just as the science of physiology and medicine relies on the sameness of our inner organs. [...] The monstrous sameness and pervasive ugliness so highly characteristic of the findings of modern psychology, and contrasting so obviously with the enormous variety and richness of overt human conduct, witness to the radical difference between the inside and the outside of the human body.

An optimistic view of the future would indicate that before long, the clear necessity of expanding humanity's horizons would cause ... space settlements to be built. The construction would also serve as a great project that not only would be clearly of great benefit, but might induce human cooperation in something large enough to fire the heart and mind, and make people forget the petty quarrels that have engaged them for thousands of years in wars over insignificant scraps of earthly territory.

Not only must philosophy be in agreement with our empirical knowledge of Nature, but the origin and formation of the Philosophy of Nature presupposes and is conditioned by empirical physics. However, the course of a science's origin and the preliminaries of its construction are one thing, while the science itself is another. In the latter, the former can no longer appear as the foundation of the science; here, the foundation must be the necessity of the Concept.

The philosophy of Plotinus has the defect of encouraging men to look within rather than to look without: when we look within we see nous, which is divine, while when we look without we see the imperfections of the sensible world. This kind of subjectivity was a gradual growth; it is to be found in the doctrines of Protagoras, Socrates, and Plato, as well as in the Stoics and Epicureans. But at first it was only doctrinal, not temperamental; for a long time it failed to kill scientific curiosity. [...] Plotinus is both an end and a beginning-an end as regards the Greeks, a beginning as regards Christendom.

If the only alternative to fascism we produce is a corporate-driven, milquetoast, neoliberal Democratic Party, fascism will come to America. Let us be very clear. It's like a Weimar America.

Have ye understood all these things? 13:51 (KJV)

All human activity is prompted by desire. There is a wholly fallacious theory advanced by some earnest moralists to the effect that it is possible to resist desire in the interests of duty and moral principle. I say this is fallacious, not because no man ever acts from a sense of duty, but because duty has no hold on him unless he desires to be dutiful. If you wish to know what men will do, you must know not only, or principally, their material circumstances, but rather the whole system of their desires with their relative strengths.

The Autarch maintained his indifferent calm, but a certain lack of certainty was gathering, and he did not like to experience a lack of certainty. He liked nothing which made him aware of limitations. An Autarch should have no limitations, and on Lingane he had none that natural law did not impose.

The greatest problem for the human race, to the solution of which Nature drives man, is the achievement of a universal civic society which administers law among men.

Imagine yourself as a living house. God comes in to rebuild that house. At first, perhaps, you can understand what He is doing. He is getting the drains right and stopping the leaks in the roof and so on: you knew that those jobs needed doing and so you are not surprised. But presently he starts knocking the house about in a way that hurts abominably and does not seem to make sense. What on earth is He up to? The explanation is that He is building quite a different house from the one you thought of-throwing out a new wing here, putting on an extra floor there, running up towers, making courtyards. You thought you were going to be made into a decent little cottage: but He is building a palace. He intends to come and live in it Himself.

Go further, and require each of them to make a contribution: you will see how many things are still missing, and you will be obliged to get the assistance of a large number of men who belong to different classes, priceless men, but to whom the gates of the academies are nonetheless closed because of their social station. All the members of these learned societies are more than is needed for a single object of human science; all the societies together are not sufficient for a science of man in general.

Choose a wife who is of character, because that one is good who in the end is more respected.

Blessed are the hearts that can bend; they shall never be broken.

Pay attention to your enemies, for they are the first to discover your mistakes.

There is needed, no doubt, a body of servants (ministerium) of the invisible church, but not officials (officiales), in other words, teachers but not dignitaries, because in the rational religion of every individual there does not yet exist a church as a universal union (omnitudo collectiva).

With rebellion, awareness is born.

A witty saying proves nothing.

A character is never the author who created him. It is quite likely, however, that an author may be all his characters simultaneously.

The Calculus required continuity, and continuity was supposed to require the infinitely little; but nobody could discover what the infinitely little might be.

His heart was as great as the world, but there was no room in it to hold the memory of a wrong.

I have resolved to demonstrate by a certain and undoubted course of argument, or to deduce from the very condition of human nature, not what is new and unheard of, but only such things as agree best with practice.

The light dove, cleaving the air in her free flight, and feeling its resistance, might imagine that its flight would be still easier in empty space.

The goal of maximizing the welfare of all may be better achieved by an ethic that accepts our inclinations and harnesses them so that, taken as a whole, the system works to everyone's advantage.

It is sweet and honorable to die for one's country.
