Unless man have a natural bent in accordance with nature's, he has no chance of understanding nature at all.

Classical science was based upon the belief that it is possible to formulate both the position and velocity at one time of any given particle. It followed that knowledge of the position and velocity of a given number of particles would enable the future behavior of the whole collection to be accurately predicted. The principle of Heisenberg is that given the determination of position, its velocity can be stated only as of a certain order of probability, while if its velocity is determined the correlative factor of position can be stated only as of a certain order of probability. Both cannot be determined at once, from which it follows necessarily that the future of the whole collection cannot possibly be foretold except in terms of some order of probability.

Act as if what you do makes a difference. It does.

The first revolt is against the supreme tyranny of theology, of the phantom of God. As long as we have a master in heaven, we will be slaves on earth.

What I know wreaks havoc upon what I want.

But if Germany, thanks to Hitler and his successors, were to enslave the European nations and destroy most of the treasures of their past, future historians would certainly pronounce that she had civilized Europe.

To do the opposite of something is also a form of imitation, namely an imitation of its opposite.

Some day you will be old enough to start reading fairy tales again.

All savageness is a sign of weakness.

The effect of liberty to individuals is, that they may do what they please: we ought to see what it will please them to do, before we risk congratulations.

Although the Law of Reason is common, the majority of people live as though they had an understanding of their own.

I am for freedom of religion, & against all maneuvres to bring about a legal ascendancy of one sect over another, for freedom of the press, and against all violations of the Constitution to silence by force and not by reason the complaints or criticisms, just or unjust, of our citizens against the conduct of their agents.

The Communist Party has one objective: the creation of a socialist economy; and one means: the utilization of the class struggle.

Justice respects man as living in society, and is the common bond without which no society can subsist.

It is not that I am mad, it is only that my head is different from yours.

Who is going to educate the human race in the principles and practice of conservation?

What makes it so plausible to assume that hypocrisy is the vice of vices is that integrity can indeed exist under the cover of all other vices except this one. Only crime and the criminal, it is true, confront us with the perplexity of radical evil; but only the hypocrite is really rotten to the core.

Gaiety - a quality of ordinary men. Genius always presupposes some disorder in the machine.

Remember that what pulls the strings is the force hidden within; there lies the power to persuade, there the life,-there, if one must speak out, the real man.

Above all, avoid falsehood, every kind of falsehood, especially falseness to yourself. Watch over your own deceitfulness and look into it every hour, every minute.

No particular experiences are linked with any particular statements in the interior of the field, except indirectly through considerations of equilibrium affecting the field as a whole.

It is better wither to be silent, or to say things of more value than silence. Sooner throw a pearl at hazard than an idle or useless word; and do not say a little in many words, but a great deal in a few.

Immature love says: "I love you because I need you." Mature love says: "I need you because I love you."

You venerate the saints, and you take pleasure in touching their relics. But you disregard their greatest legacy, the example of a blameless life. No devotion is more pleasing to Mary than the imitation of Mary's humility. No devotion is more acceptable and proper to the saints than striving to imitate their virtues.

In the long run, there is nothing to stop intelligent agents from identifying the molecular signature of experience below hedonic zero and eliminating it altogether - even in insects. Nociception is vital; pain is optional. I tentatively predict that the world's last unpleasant experience in our forward light-cone will be a precisely datable event - perhaps some micro-pain in an obscure marine invertebrate a few centuries hence.

Now, what is 'unrighteousness' in practice? It is in practice behavior of a kind disliked by the herd. By calling it unrighteousness, and by arranging an elaborate system of ethics around this conception, the herd justifies itself in wreaking punishment upon the objects of its own dislike, while at the same time, since the herd is righteous by definition, it enhances its own self-esteem at the very moment when it lets loose its impulse to cruelty. This is the psychology of lynching, and of the other ways in which criminals are punished. The essence of the conception of righteousness, therefore, is to afford an outlet for sadism by cloaking cruelty as justice.

He would be the finer gentleman that should leave the world without having tasted of lying or pretence of any sort, or of wantonness or conceit.

Do you count your birthdays with gratitude?

To forget the wrongs you receive, is to remedy them.

The doors of heaven and hell are adjacent and identical.

To me, believing that some correspondence intrinsically just is reference (not as a result of our operational and theoretical constraints, or our intentions, but as an ultimate metaphysical fact) amounts to a magical theory of reference. Reference itself becomes what Locke called a 'substantial form' (an entity which intrinsically belongs with a certain name) on such a view. Even if one is willing to contemplate such unexplainable metaphysical facts, the epistemological problems that accompany such a metaphysical view seem insuperable. For, assuming a world of mind- independent, discourse-independent entities (this is the presupposition of the view we are discussing), there are, as we have seen, many different 'correspondences' which represent possible or candidate reference relations (infinitely many, in fact, if there are infinitely many things in the universe).

But voice is a certain sound of that which is animated; for nothing inanimate emits a voice; but they are said to emit a voice from similitude, as a pipe, and a lyre, and such other inanimate things, have extension, modulation, and dialect; for thus it appears, because voice, also, has these.

We should have with each person the relationship of one conception of the universe to another conception of the universe, and not to a part of the universe.

The form most contradictory to human life that can appear among the human species is the "self-satisfied man."

The legacy of modernity is a legacy of fratricidal wars, devastating "development," cruel "civilization," and previously unimagined violence. Erich Auerbach once wrote that tragedy is the only genre that can properly claim realism in Western literature, and perhaps this is true precisely because of the tragedy Western modernity has imposed on the world.

It may possibly be true that, to continue to live on and to act in a world like ours, it is vitally necessary to seek a way out of this uncertainty of multiple alternatives; and accordingly people may be led to embrace some immediate goal as if it were absolute, by which they hope to make their problems appear concrete and real. But it is not primarily the man of action who seeks the absolute and immutable, but rather it is he who wishes to induce others to hold on to the status quo because he feels comfortable and smug under conditions as they are.

Love is ever the beginning of Knowledge as fire is of light.

Enlighten the dark blood of your ancestors, shape their cries into speech, purify their will, widen their narrow, unmerciful brows. This is your second duty. For you are not only a slave. As soon as you were born, a new possibility was born with you, a free heartbeat stormed through the great sunless heart of your race.

Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience. They may be more likely to go to Heaven yet at the same time likelier to make a Hell of earth. This very kindness stings with intolerable insult. To be "cured" against one's will and cured of states which we may not regard as disease is to be put on a level of those who have not yet reached the age of reason or those who never will; to be classed with infants, imbeciles, and domestic animals.

In all human affairs, and especially in those that relate to war, ...leave always some room to fortune, and to accidents which cannot be foreseen.

The rather more dubious side of Nietzsche's 'evolutionism' is his glorification of the warrior -- particularly when, as an exemplification of the warrior-hero, he chooses an archetypal 'spoilt brat' like Cesare Borgia. Nietzsche's own physical weakness and consequent inability to escape the atmosphere of the study leads him to take a rather unrealistic view of the man of action.

Whoever drinks from my mouth will become like me; I myself shall become that person, and the hidden things will be revealed to him.

Character is higher than intellect...A great soul will be strong to live, as well as strong to think.

Cultural dominance by either the left or the right hemisphere is largely dependent upon environmental factors.

What Heaven has conferred is called The Nature; an accordance with this nature is called The Path of duty; the regulation of this path is called Instruction. The path may not be left for an instant. If it could be left, it would not be the path. On this account, the superior man does not wait till he sees things, to be cautious, nor till he hears things, to be apprehensive.

The deadliest enemies of nations are not their foreign foes; they always dwell within their borders. And from these internal enemies civilization is always in need of being saved. The nation blest above all nations is she in whom the civic genius of the people does the saving day by day, by acts without external picturesqueness; by speaking, writing, voting reasonably; by smiting corruption swiftly; by good temper between parties; by the people knowing true men when they see them, and preferring them as leaders to rabid partisans or empty quacks.
