One must be something in order to do something.

It is useless to try to adjudicate a long-standing animosity by asking who started it or who is the most wrong. The only sufficient answer is to give up the animosity and try forgiveness, to try to love our enemies and to talk to them and (if we pray) to pray for them. If we can't do any of that, then we must begin again by trying to imagine our enemies' children who, like our children, are in mortal danger because of enmity that they did not cause.

Apart from any other basis which might justify a superiority, education, as a power, raised him who possessed it over the weak, who lacked it, and the educated man counted in his circle, however large or small it was, as the mighty, the powerful, the imposing one: for he was an authority.

The reproduction of mankind is a great marvel and mystery. Had God consulted me in the matter, I should have advised him to continue the generation of the species by fashioning them of clay, in the way Adam was fashioned.

The really important facts were that spatial relationships had ceased to matter very much and that my mind was perceiving the world in terms of other than spatial categories. At ordinary times the eye concerns itself with such problems as where? - how far? - how situated in relation to what? In the mescaline experience the implied questions to which the eye responds are of another order. Place and distance cease to be of much interest. The mind does its perceiving in terms of intensity of existence, profundity of significance, relationships within a pattern."

Philosophy is in history, and is never independent of historical discourse. But for the tacit symbolism of life it substitutes, in principle, a conscious symbolism; for a latent meaning, one that is manifest. It is never content to accept its historical situation. It changes this situation by revealing it to itself.

If the Jew did not exist, the anti-Semite would invent him.

The Roman came into the Promised Land that had become less and less as promised. The rich got along quite well with the foreign occupation; it provided protection from desperate peasants and patriotic resistance fighters. It provided protection from prophets who could be labeled "agitators" now, without any qualms.

Extreme pride or dejection indicates extreme ignorance of self.

Every philosophy is complete in itself and, like a genuine work of art, contains the totality. Just as the works of Apelles and Sophocles, if Raphael and Shakespeare had known them, should not have appeared to them as mere preliminary exercises for their own work, but rather as a kindred force of the spirit, so, too reason cannot find in its own earlier forms mere useful preliminary exercises for itself.

Communism differs from all previous movements in that it overturns the basis of all earlier relations of production and intercourse, and for the first time consciously treats all natural premises as the creatures of hitherto existing men, strips them of their natural character and subjugates them to the power of the united individuals. Its organisation is, therefore, essentially economic, the material production of the conditions of this unity; it turns existing conditions into conditions of unity. The reality, which communism is creating, is precisely the true basis for rendering it impossible that anything should exist independently of individuals, insofar as reality is only a product of the preceding intercourse of individuals themselves.

It is dangerous to be right in matters where established men are wrong.

Nay, am not I also the humble James Carlyle's work? I owe him much more than existence, I owe him a noble inspiring example (now that I can read it in that rustic character). It was he exclusively that determined on educating me; that from his small hard-earned funds sent me to school and college, and made me whatever I am or may become. Let me not mourn for my father, let me do worthily of him. So shall he still live even here in me, and his worth plant itself honorably forth into new generations.

It is quite possible to be both. I look upon myself as a man. Nationalism is an infantile disease. It is the measles of mankind.

The Age of Writing has passed. We must invent a new metaphor, restructure our thoughts and feelings.

Landlords... grow richer, as it were in their sleep, without working, risking, or economizing.

It is impossible to feel equal respect for things that are in fact unequal unless the respect is given to something that is identical in all of them. Men are unequal in all their relations with the things of this world, without exception. The only thing that is identical in all men is the presence of a link with the reality outside the world. All human beings are absolutely identical in so far as they can be thought of as consisting of a centre, which is an unquenchable desire for good, surrounded by an accretion of psychical and bodily matter.

When God chooses to let himself be born in lowliness, when he who holds all possibilities in his hand takes upon himself the form of a lowly servant, when he goes about defenseless and lets people do with him what they will, he surely must know well enough what he is doing and why he wills it; but for all that it is he who has people in his power and not they who have power over him-so history ought not play Mr. Malapert by this wanting to make manifest who he was.

In conditions of private property ... "life-activity" stands in the service of property instead of property standing the service of free life-activity.

But of such writers the number is yet (and will I fear always be so) small, that I shall not need to make many exceptions, when I treat of the usefulness of writing books of essays, in comparison of that of writing systematically: or, at least... whilst I presume not to judge of other men's abilities, I hope it may be lawful for me to confess freely to you concerning myself, that I am very sensible of my being far from having such a stock of experiments and observations, as I judge requisite to write systematically; and I am apt to impute many of the deficiencies to be met with in the theories and reasonings of such great wits as Aristotle, Campanella, and some other celebrated philosophers, chiefly to this very thing, that they have too hastily, and either upon a few observations, or at least without a competent number of experiments, presumed to establish principles, and deliver axioms.

They say cowardice is infectious; but then argument is, on the other hand, a great emboldener.

There is another significant involution of time and movement in space. It is constituted not only by directional tendencies-up and down for example-but by mutual approaches and retreatings. Near and far, close and distant, are qualities of pregnant, often tragic, import-that is, as they are experienced, not just stated by measurement of science. They signify loosening and tightening, expanding and contracting, separating and compacting, soaring and drooping, rising and falling; the dispersive, scattering, and the hovering and brooding, unsubstantial lightness and massive blow. Such actions and reaction are the very stuff out if which the objects and events we experience are made.

A habit of basing convictions upon evidence, and of giving to them only that degree of certainty which the evidence warrants, would, if it became general, cure most of the ills from which the world is suffering. But at present, in most countries, education aims at preventing the growth of such a habit, and men who refuse to profess belief in some system of unfounded dogmas are not considered suitable as teachers of the young.

My own long struggle to find my bearings, the disillusionments and disappointments I had experienced, had made me less dogmatic in my demands on people than I had been. They had helped me to understand the hard and lonely life of the rebel who had fought for an unpopular cause. Whatever bitterness I had felt against my old teacher had given way to deep sympathy long before his death. (about Johann Most)

Consciousness must essentially cover an interval of time; for if it did not, we could gain no knowledge of time, and not merely no veracious cognition of it, but no conception whatever. We are therefore, forced to say that we are immediately conscious through an infinitesimal interval of time.

Whenever the general disposition of the people is such, that each individual regards those only of his interests which are selfish, and does not dwell on, or concern himself for, his share of the general interest, in such a state of things, good government is impossible.

Survival machines that can simulate the future are one jump ahead of survival machines that who can only learn of the basis of trial and error. The trouble with overt trial is that it takes time and energy. The trouble with overt error is that it is often fatal. ...The evolution of the capacity to simulate seems to have culminated in subjective consciousness. Why this should have happened is, to me, the most profound mystery facing modern biology.

I regret that I am now to die in the belief, that the useless sacrifice of themselves by the generation of 1776, to acquire self- government and happiness to their country, is to be thrown away by the unwise and unworthy passions of their sons, and that my only consolation is to be, that I live not to weep over it. If they would but dispassionately weigh the blessings they will throw away, against an abstract principle more likely to be effected by union than by scission, they would pause before they would perpetrate this act of suicide on themselves, and of treason against the hopes of the world. To yourself, as the faithful advocate of the Union, I tender the offering of my high esteem and respect.

The aim of the book is to set a limit to thought, or rather - not to thought, but to the expression of thoughts: for in order to be able to set a limit to thought, we should have to find both sides of the limit thinkable (i.e. we should have to be able to think what cannot be thought). It will therefore only be in language that the limit can be set, and what lies on the other side of the limit will simply be nonsense.

Corn is a necessary, silver is only a superfluity.

In fact, it is as difficult to appropriate the thoughts of others as it is to invent.

Struggling to be brief I become obscure.

A trifling debt makes a man your debtor; a large one makes him an enemy.

It is surely better to be wronged than to do wrong.

I have ever loved to repose myself, whether sitting or lying, with my heels as high or higher than my head.

The phenomenon of the will in Epictetus, a different mental ability whose chief characteristic is that it speaks an imperative even when it commands nothing but our ability to think. The goal is to annihilate reality insofar it concerns me.

The first consequence of the principle of bounded rationality is that the intended rationality of an actor requires him to construct a simplified model of the real situation in order to deal with it. He behaves rationally with respect to this model, and such behavior is not even approximately optimal with respect to the real world. To predict his behavior we must understand the way in which this simplified model is constructed, and its construction will certainly be related to his psychological properties as a perceiving, thinking, and learning animal.

Recognition of the subjectivity of the qualities of sense is found in Galilei (and also in Descartes and Hobbes) in a form closely related to the principle underlying the constructive mathematical method of our modern physics which repudiates" qualities".

Nothing is great but truth, and the smallest truth is great. The other day I had a thought, which I put like this: Even a harmful truth is useful, for it can be harmful only for the moment and will lead to other truths, which must always become useful, very much so. Conversely, even a useful error is harmful, for it can be useful only for the moment, enticing us into other errors, which become more and more harmful.

The saying that beauty is but skin deep is but a skin-deep saying.

One might think that it must be quite clear to people not deprived of reason, that violence breeds violence; that the only means of deliverance from violence lies in not taking part in it. This method, one would think, is quite obvious. It is evident that a great majority of men can be enslaved by a small minority only if the enslaved themselves take part in their own enslavement. If people are enslaved, it is only because they either fight violence with violence or participate in violence for their own personal profit. Those who neither struggle against violence nor take part in it can no more be enslaved than water can be cut. They can be robbed, prevented from moving about, wounded or killed, but they cannot be enslaved: that is, made to act against their own reasonable will.

I entirely agree with you, as to the ill tendency of the affected doubts of some philosophers, and fantastical conceit of others. I am even so far gone of late in this way of think, that I have quitted several of the sublime notions I had got in their schools for vulgar opinions. And I give it you on my word, since this revolt from metaphysical notions to the plain dictates of nature and common sense, I find my understanding strangely enlightened, so that I can now easily comprehend a great many thing which before were all mystery and riddle.

In an article published in The Monist for January, 1891, I endeavored to show what ideas ought to form the warp of a system of philosophy, and particularly emphasized that of absolute chance. In the number of April, 1892, I argued further in favor of that way of thinking, which it will be convenient to christen tychism (from τύχη, chance). A serious student of philosophy will be in no haste to accept or reject this doctrine; but he will see in it one of the chief attitudes which speculative thought may take, feeling that it is not for an individual, nor for an age, to pronounce upon a fundamental question of philosophy. That is a task for a whole era to work out. I have begun by showing that tychism must give birth to an evolutionary cosmology, in which all the regularities of nature and of mind are regarded as products of growth, and to a Schelling-fashioned idealism which holds matter to be mere specialized and partially deadened mind.

Once you've dissected a joke, you're about where you are when you've dissected a frog. It's dead. 

This avidity alone, of acquiring goods and possessions for ourselves and our nearest friends, is insatiable, perpetual, universal, and directly destructive of society.
