And suddenly I had an inkling of what it must feel like to be mad.

Outside the academic establishment, the "far-reaching change in all our habits of thought" is more serious. It serves to coordinate ideas and goals with those exacted by the prevailing system, to enclose them in the system, and to repel those which are irreconcilable with the system. The reign of such a one-dimensional reality does not mean that materialism rules, and that the spiritual, metaphysical, and bohemian occupations are petering out. On the contrary, there is a great deal of "Worship together this week," "Why not try God," Zen, existentialism, and beat ways of life, etc. But such modes of protest and transcendence are no longer contradictory to the status quo and no longer negative. They are rather the ceremonial part of practical behaviorism, its harmless negation, and are quickly digested by the status quo as part of its healthy diet.

A heart without music is like beauty without melancholy.

The infinite is in capacity. That, however, which is infinite in capacity is not to be assumed as that which is infinite in energy. ...It has its being in capacity, and in division and diminution. ...It is always possible to assume something beyond it. It does not, however, on this account surpass every definite magnitude; as in division it surpasses every definite magnitude, and will be less.

The physical change in the thickness of walls since the Middle Ages could be shown in a diagram. In the fourteenth century each house was a fortress. Man spent the major portion of his day in them, in secret and well-defended solitude. That solitude, working on the soul hour after hour, forged it, like a transcendent blacksmith, into a compact and forceful character. Under its treatment, man consolidated his individual destiny and sallied forth with impunity, never yielding to the contamination from the public. It is only in isolation that we gain, almost automatically, a certain discrimination in ideas, desires, longings, that we learn which are ours, and which are anonymous, floating in the air, falling on us like dust in the street.

I have come to believe that the motion of the Earth cannot be detected by any optical experiment.

At puberty, the elements of an unsuperstitious sexual morality ought to be taught. Boys and girls should be taught that nothing can justify sexual intercourse unless there is mutual inclination... Boys and girls should be taught respect for each other's liberty; they should be made to feel that nothing gives one human being rights over another, and that jealousy and possessiveness kill love. They should be taught that to bring another human being into the world is a very serious matter, only to be undertaken when the child will have a reasonable prospect of health, good surroundings, and parental care. But they should also be taught methods of birth control, so as to insure that children shall only come when they are wanted. Finally, they should be taught the dangers of venereal disease, and the methods of prevention and cure. The increase of human happiness to be expected from sex education on these lines is immeasurable.

But the capacity to enjoy is impossible without the capacity to suffer; and the faculty of enjoyment is one with that of pain. Whosoever does not suffer does not enjoy, just as whosoever is insensible to cold is insensible to heat.

Mankind was never so happily inspired as when it made a cathedral.

France had endeavoured under the specious pretext of an enlarged benevolence, to sow the seeds of enmity among nations, and destroy all local attachments, calling them narrow and illiberal-thereby to dissever the people from their governors.

There is clear truth in the idea that a struggle from the lower classes of society, towards the upper regions and rewards of society, must ever continue. Strong men are born there, who ought to stand elsewhere than there.

To be happy, we must not be too concerned with others.

It is not easy for any of us to stop measuring the world against the standard of Europe, but the concept of the multitude requires it of us. It is a challenge. Embrace it.

If you say that this is absurd, that we cannot be in love with everyone at once, I merely point out to you that, as a matter of fact, certain persons do exist with an enormous capacity for friendship and for taking delight in other people's lives; and that such person know more of truth than if their hearts were not so big. The vice of ordinary Jack and Jill affection is not its intensity, but its exclusions and its jealousies. Leave those out, and you see that the ideal I am holding up before you, however impracticable to-day, yet contains nothing intrinsically absurd.

Whatever we may think or affect to think of the present age, we cannot get out of it; we must suffer with its sufferings, and enjoy with its enjoyments; we must share in its lot, and, to be either useful or at ease, we must even partake its character.

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

Consider what you have in the smallest chosen library. A company of the wisest and wittiest men that could be picked out of all civil countries, in a thousand years, have set in best order the results of their learning and wisdom. The men themselves were hid and inaccessible, solitary, impatient of interruption, fenced by etiquette; but the thought which they did not uncover to their bosom friend is here written out in transparent words to us, the strangers of another age.

In all sectors of society there should be roughly equal prospects of culture and achievement for everyone similarly motivated and endowed. The expectations of those with the same abilities and aspirations should not be affected by their social class.

A cock has great influence on his own dunghill.

Simplify the social system, in the manner which every motive, but those of usurpation and ambition, powerfully recommends; render the plain dictates of justice level to every capacity; remove the necessity of implicit faith; and we may expect the whole species to become reasonable and virtuous.

Men who prefer any load of infamy, however great, to any pressure of taxation, however light.

The activity of art is... as important as the activity of language itself, and as universal.

Economic reforms based on the idea of limitless growth in a limited world, can only be maintained by the powerful grabbing the resources of the vulnerable. The resource grab that is essential for "growth" creates a culture of rape-the rape of the earth, of local self-reliant economies, and of women.

And some others that I have seen, were perhaps among the first. There is no third rising. Time sweeps all away with it so fast at this epoch. The Scottish Church has been short-lived, and was late in reaching thither.

And striving to be man, the worm Mounts through all the spires of form.

The deceiver is really the fool.

If I had had more time, this letter would have been shorter.

I am dreaming ...? Let me dream, if this dream is my life. Do not awaken me from it. I believe in the immortal origin of this yearning for immortality, which is the very substance of my soul. But do I really believe in it ...? And wherefore do you want to be immortal? you ask me, wherefore? Frankly, I do not understand the question, for it is to ask the reason of the reason, the end of the end, the principle of the principle.

While in the West, the insane are so many that they are put in an asylum, in China the insane are so unusual that we worship them, as anybody who has a knowledge of Chinese literature will testify.

If someone is merely ahead of his time, it will catch up to him one day.

Men accept servility in order to acquire wealth; as if they could acquire anything of their own when they cannot even assert that they belong to themselves.

The music that can deepest reach, And cure all ill, is cordial speech.

"Where do you get those superior airs of yours?" "I've managed to survive, you see, all those nights when I wondered: am I going to kill myself at dawn?"

Paradise was unendurable, otherwise the first man would have adapted to it; this world is no less so, since here we regret paradise or anticipate another one. What to do? Where to go? Do nothing and go nowhere, easy enough.

Newton's law is nothing but the statistics of gravitation, it has no power whatever. Let us get rid of the idea of power from law altogether. Call law tabulation of facts, expression of facts, or what you will; anything rather than suppose that it either explains or compels.

Where men are the most sure and arrogant, they are commonly the most mistaken, and have there given reins to passion, without that proper deliberation and suspense, which can alone secure them from the grossest absurdities.

The Son of man shall be betrayed into the hands of men: And they shall kill him, and the third day he shall be raised again.

Earth proudly wears the Parthenon As the best gem upon her zone.

Why does God afflict the best of men with ill-health, or sorrow, or other troubles? Because in the army the most hazardous services are assigned to the bravest soldiers: a general sends his choicest troops to attack the enemy in a midnight ambuscade, to reconnoitre his line of march, or to drive the hostile garrisons from their strong places. No one of these men says as he begins his march, " The general has dealt hardly with me," but "He has judged well of me."

Thou shalt do no murder, Thou shalt not commit adultery, Thou shalt not steal, Thou shalt not bear false witness, Honour thy father and thy mother: and, Thou shalt love thy neighbour as thyself.

The mind must not be forced; artificial and constrained manners fill it with foolish presumption, through unnatural elevation and vain and ridiculous inflation, instead of solid and vigorous nutriment.

Like nonhuman animals in human factory farms, free-living nonhumans who are starving - or being disembowelled, asphyxiated or eaten alive - cannot console themselves by chanting the Four Noble Truths of Buddhism. The moral case for helping other sentient beings, regardless or race or species, does not rest on the distress their plight does (or doesn't) cause spectators.

At best the principles that economists have supposed the choices of rational individuals to satisfy can be presented as guidelines for us to consider when we make our decisions.
