The wise man should restrain his senses like the crane and accomplish his purpose with due knowledge of his place, time and ability.

Old age realizes the dreams of youth: look at Dean Swift; in his youth he built an asylum for the insane, in his old age he was himself an inmate.

We are beggars: this is true.

I tell you in truth: all men are Prophets or else God does not exist.

Natural selection is like artificial selection, but without the human chooser. Instead of a human deciding which offspring shall die in which shall reproduce, nature 'decides'. The quotation marks are vital because nature doesn't consciously decide. This might seem too obvious to emphasize, but you'd be surprised by the number of people who think natural selection implies some kind of personal choice. They couldn't be more wrong. It just is the case that some offspring are more likely to die while others have what it takes to survive and reproduce. Therefore, as the generations go by, the average, typical creature in the population becomes ever better at the arts of surviving and reproducing. Ever better, I should specify, when, when measured against some absolute standard.

But to return to the Jewish question. Other groups and nations cultivate their individual traditions. There is no reason why we should sacrifice ours. Standardization robs life of its spice. To deprive every ethnic group of its special traditions is to convert the world into a huge Ford plant. I believe in standardizing automobiles. I do not believe in standardizing human beings. Standardization is a great peril which threatens American culture.

Americans cleave to the things of this world as if assured that they will never die,... They clutch everything but hold nothing fast, and so lose grip as they hurry after some new delight. ... Death steps in in the end and stops him before he has grown tired of this futile pursuit of that complete felicity which always escapes him. At first sight there is something astonishing in this spectacle of so many lucky men restless in the midst of abundance. But it is a spectacle as old as the world; all that is new is to see a whole people performing in it.

Let every man be occupied, and occupied in the highest employment of which his nature is capable, and die with the consciousness that he has done his best.

One sticks one's finger into the soil to tell by the smell in what land one is: I stick my finger in existence - it smells of nothing. Where am I? Who am I? How came I here? What is this thing called the world? What does this world mean? Who is it that has lured me into the world? Why was I not consulted, why not made acquainted with its manners and customs instead of throwing me into the ranks, as if I had been bought by a kidnapper, a dealer in souls? How did I obtain an interest in this big enterprise they call reality? Why should I have an interest in it? Is it not a voluntary concern? And if I am to be compelled to take part in it, where is the director? I should like to make a remark to him. Is there no director? Whither shall I turn with my complaint?

If we take a survey of ages and of countries, we shall find the women, almost - without exception - at all times and in all places, adored and oppressed. Man, who has never neglected an opportunity of exerting his power, in paying homage to their beauty, has always availed himself of their weakness He has been at once their tyrant and their slave.

The desire to die was my one and only concern; to it I have sacrificed everything, even death.

All things in nature become identical with the phenomena they present when submitted to the practices of our laboratories, whose problems no less than their apparatus express in turn the problems and interests of society as it is. This view may be compared with that of a criminologist maintaining that trustworthy knowledge of a human being can be obtained only by the well-tested and streamlined examining methods applied to a suspect in the hands of the metropolitan police.

Capitalist production, therefore, develops technology, and the combining together of various processes into a social whole, only by sapping the original sources of all wealth - the soil and the labourer.

In cloning, the Father and the Mother have disappeared, not in the service of an aleatory liberty of the subject, but in the service of a matrix called code.

In order to enjoy the inestimable benefits that the liberty of the press ensures, it is necessary to submit to the inevitable evils it creates.

Oh! wherefore come ye forth, in triumph from the North,With your hands, and your feet, and your raiment all red? And wherefore doth your rout send forth a joyous shout? And whence be the grapes of the wine-press which ye tread?

If the only significant history of human thought were to be written, it would have to be the history of its successive regrets and its impotences.

Everyone sits in the prison of his own ideas; he must burst it open, and that in his youth, and so try to test his ideas on reality.

He is a fool who lets slip a bird in the hand for a bird in the bush.

The most thought provoking thing in our thought provoking time is that we are still not thinking.

The young generations of the world, who had in them the freshness of young children, and yet the depth of earnest men, who did not think that they had finished off all things in Heaven and Earth by merely giving them scientific names, but had to gaze direct at them there, with awe and wonder: they felt better what of divinity is in man and Nature; they, without being mad, could worship Nature, and man more than anything else in Nature.

The universe comprises all being in a totality; for nothing that exists is outside or beyond infinite being, as the latter has no outside or beyond.

In the present situation, such an experiment would be doubly dangerous to the Russian Social Democracy. It stands on the eve of decisive battles against tsarism. It is about to enter, or has already entered, on a period of intensified creative activity, during which it will broaden (as is usual in a revolutionary period) its sphere of influence and will advance spontaneously by leaps and bounds. To attempt to bind the initiative of the party at this moment, to surround it with a network of barbed wire, is to render it incapable of accomplishing the tremendous task of the hour.

It is not to be supposed that she was, or that any one, at the age at which I first saw her, could be, all that she afterwards became. Least of all could this be true of her, with whom self-improvement, progress in the highest and in all senses, was a law of her nature; a necessity equally from the ardour with which she sought it, and from the spontaneous tendency of faculties which could not receive an impression or an experience without making it the source or the occasion of an accession of wisdom. Up to the time when I first saw her, her rich and powerful nature had chiefly unfolded itself according to the received type of feminine genius. To her outer circle she was a beauty and a wit, with an air of natural distinction, felt by all who approached her: to the inner, a woman of deep and strong feeling, of penetrating and intuitive intelligence, and of an eminently meditative and poetic nature.

After the battle in Pharsalia, when Pompey was fled, one Nonius said they had seven eagles left still, and advised to try what they would do. "Your advice," said Cicero, "were good if we were to fight jackdaws."

The Virgin Mary remains in the middle between Christ and humankind. For in the very moment he was conceived and lived, he was full of grace. All other human beings are without grace, both in the first and second conception. But the Virgin Mary, though without grace in the first conception, was full of grace in the second ... whereas other human beings are conceived in sin, in soul as well as in body, and Christ was conceived without sin in soul as well as in body, the Virgin Mary was conceived in body without grace but in soul full of grace.

Lysander said, "Where the lion's skin will not reach, it must be pieced with the fox's."

Genuine time, if it exists as anything else except the measure of motions in space, is all one with the existence of individuals as individuals, with the creative, with the occurrence of unpredictable novelties. Everything that can be said contrary to this conclusion is but a reminder that an individual may lose his individuality, for individuals become imprisoned in routine and fall to the level of mechanisms. Genuine time then ceases to be an integral element of their being. Our behavior becomes predictable, because it is but an external rearrangement of what went before.

When I speak of 'negative dialectics' not the least important reason for doing so is my desire to dissociate myself from this fetishization of the positive.

Objectification is above all exteriorization, the alienation of spirit from itself.

Necessity resides in the way we talk about things, not in the things we talk about.

Death is the dark backing that a mirror needs if we are to see anything.

Genius borrows nobly. When Shakespeare is charged with debts to his authors, Landor replies: "Yet he was more original than his originals. He breathed upon dead bodies and brought them into life."

This is a fine saying of Plato: That he who is discoursing about men should look also at earthly things as if he viewed them from some higher place; should look at them... a mixture of all things and an orderly combination of contraries.

I sit astride life like a bad rider on a horse. I only owe it to the horse's good nature that I am not thrown off at this very moment.

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

There are two great fundamental problems common to all thought: (i) the problem of world- and life-affirmation and world- and life-negation, and (2) the problem of ethics and the relations between ethics and these two forms of man's spiritual attitude to Being.

People who live in society have learned how to see themselves in mirrors as they appear to their friends. I have no friends. Is that why my flesh is so naked?

One that confounds good and evil is an enemy to the good.

The precise reason why abstinence from animal food will be the first act ... of a moral life is admirably explained in the book, The Ethics of Diet [by Howard Williams]; and not by one man only, but by all mankind in the persons of its best representatives during all the conscious life of humanity. ... the moral progress of humanity - which is the foundation of every other kind of progress - is always slow; but ... the sign of true, not casual, progress is its uninterruptedness and its continual acceleration. And the progress of vegetarianism is of this kind. That progress, is expressed both in the words of the writers cited in the above-mentioned book and in the actual life of mankind, which from many causes is involuntarily passing metre and more from carnivorous habits to vegetable food, and is also deliberately following the same path in a movement which shows evident strength, and which is growing larger and larger - viz., vegetarianism.

Dead of night. No one, nothing but the society of the moments. Each pretends to keep us company, then escapes - desertion after desertion.

If you don't know how to die, don't worry; Nature will tell you what to do on the spot, fully and adequately. She will do this job perfectly for you; don't bother your head about it.

We are but dust and shadow.

Know, first, who you are, and then adorn yourself accordingly.

Botany is the school for patience, and it's amateurs learn resignation from daily disappointments.
