The best books are those, which those who read them believe they themselves could have written.

You must always be puzzled by mental illness. The thing I would dread most, if I became mentally ill, would be your adopting a common sense attitude; that you could take it for granted that I was deluded.

There was a time when religion was kept secret from popular belief within the mystery cults like a holy fire, sharing a common sanctuary with philosophy. The legends of antiquity name the earliest philosophers as the originators of these mystery cults, from which the most enlightened among the later philosophers, notably Plato, liked to educe their divine teachings. At that time philosophers still had the courage and the right to discuss the singly great themes, the only ones worthy of philosophizing and rising above common knowledge.

Man grows used to everything, the scoundrel.

They pass peaceful lives who ignore mine and thine.

They that be whole need not a physician, but they that are sick. But go ye and learn what that meaneth, I will have mercy, and not sacrifice: for I am not come to call the righteous, but sinners to repentance.

It was my wish to present this great subject as an illustration of the itermingling of philosophical, mathematical, and physical thought, a study which is dear to my heart. This could be done only by building up the theory systematically from the foundations, and by restricting attention throughout to the principles. But I have not been able to satisfy these self-imposed requirements: the mathematician predominates at the expense of the philosopher.

The condemned man found himself transformed into a hero by the sheer extend of his widely advertised crimes, and sometimes the affirmation of his belated repentance. Against the law, against the rich, the powerful, the magistrates, the constabulary or the watch, against taxes and their collectors, he appeared to have waged a struggle with which one all too easily identified. The proclamation of these crimes blew up to epic proportions the tiny struggle that passed unperceived in everyday life. If the condemned man was shown to be repentant, accepting the verdict, asking both God and man for forgiveness for his crimes, it was as if he had come through some process of purification: he died, in his own way, like a saint.

In the ancient notion of love, on the other hand, there is an element of anxiety. The noble fears the descent to the less noble, is afraid of being infected and pulled down. The "sage" of antiquity does not have the same firmness, the same inner certainty of himself and his own value, as the genius and hero of Christian love.

The laws of conscience, which we pretend to be derived from nature, proceed from custom.

Volumes might be written upon the impiety of the pious.

Its first ethical precept is the identity of means used and aims sought. The ultimate end of all revolutionary social change is to establish the sanctity of human life, the dignity of man, the right of every human being to liberty and wellbeing. Unless this be the essential aim of revolution, violent social changes would have no justification. For external social alterations can be, and have been, accomplished by the normal processes of evolution. Revolution, on the contrary, signifies not mere external change, but internal, basic, fundamental change. That internal change of concepts and ideas, permeating ever-larger social strata, finally culminates in the violent upheaval known as revolution.

Becoming a vegetarian is not merely a symbolic gesture. Nor is it an attempt to isolate oneself from the ugly realities of the world, to keep oneself pure and so without responsibility for the cruelty and carnage all around. Becoming a vegetarian is a highly practical and effective step one can take toward ending both the killing of nonhuman animals and the infliction of suffering upon them.

If just once you were depressed for no reason, you have been so all your life without knowing.

Are not five sparrows sold for two farthings, and not one of them is forgotten before God? But even the very hairs of your head are all numbered. Fear not therefore: ye are of more value than many sparrows.

The manufacturing worker almost always lives in the countryside and in a more or less patriarchal relation to his landlord or employer; the proletarian lives, for the most part, in the city and his relation to his employer is purely a cash relation. The manufacturing worker is torn out of his patriarchal relation by big industry, loses whatever property he still has, and in this way becomes a proletarian.

To wish to escape from solitude is cowardice. Friendship is not to be sought, not to be dreamed, not to be desired; it is to be exercised (it is a virtue).

We believe we are rising because while keeping the same base inclinations (for instance: the desire to triumph over others) we have given them a noble object. We should, on the contrary, rise by attaching noble inclinations to lowly objects.

Live as long as you please, you will strike nothing off the time you will have to spend dead.

There is no greater fallacy than the belief that aims and purposes are one thing, while methods and tactics are another, This conception is a potent menace to social regeneration. All human experience teaches that methods and means cannot be separated from the ultimate aim. The means employed become, through individual habit and social practice, part and parcel of the final purpose; they influence it, modify it, and presently the aims and means become identical.

One reason why mathematics enjoys special esteem, above all other sciences, is that its laws are absolutely certain and indisputable, while those of other sciences are to some extent debatable and in constant danger of being overthrown by newly discovered facts.

Genet is a man-failure: he wills the impossible in order to derive from the tragic grandeur of this defeat the assurance that there is something other than the possible.

The universal intelligence puts itself in motion for every separate effect... or it puts itself in motion once, and everything else comes by way of a sequence in a manner; or individual elements are the origin of all things. In a word, if there is a god, all is well; and if chance rules, do not thou be governed by it.

The miracles in fact are a retelling in small letters of the very same story which is written across the whole world in letters too large for some of us to see. Of that larger script part is already visible, part is still unsolved. In other words, some of the miracles do locally what God has already done universally: others do locally what He has not yet done, but will do. In that sense, and from our human point of view, some are reminders and others prophecies.

What's interesting about the world today is that the fundamental division is... a... sociological one between people that have better educations, that live in big urban agglomerations, that then can then benefit from... a global economy, versus people who live in... smaller cities and towns, or in the countryside... with more traditional values. That division exists almost universally, in Turkey... Hungary... the United States, in Britain... It does reflect different economic opportunities, but more fundamentally... it reflects a... way of life, that in the urban case is... liberal and open, but in some cases... people would say a little... too open and too tolerant of... people that want to break traditional norms that are still maintained by... other parts of the population. So it's really that cultural fight... that's at the center of populism, related to,.. but certainly not fundamentally driven by economic inequality.

The mad mob does not ask how it could be better, only that it be different. And when it then becomes worse, it must change again. Thus they get bees for flies, and at last hornets for bees. Whether Soldiers Can Also Be in a State of Grace

Every commodity is compelled to chose some other commodity for its equivalent.

It's easier for a Russian to become an atheist than for anyone else in the world.

Once we have tasted the sweetness of what is spiritual, the pleasures of the world will have no attraction for us. If we disregard the shadows of things, then we will penetrate their inner substance.

Our psychological experiences are all equally facts. There is nothing to choose between them. No psychological experience is "truer," so far as we are concerned, than any other. For even if one should correspond more closely to things in themselves as perceived by some hypothetical non-human being, it would be impossible for us to discover which it was. Science is no "truer" than common sense, or lunacy, or art, or religion. It permits us to organize our experience profitably; but tells us nothing about the real nature of the world to which our experiences are supposed to refer. From the internal reality, by which I mean the totality of psychological experiences, it actually separates us. Art, for example, deals with many more aspects of this internal reality than does science, which confines itself deliberately and by convention to the study of one very limited class of experiences - the experiences of sense.

Nearly allied to justice are the virtues of beneficence, compassion, gratitude, piety, and friendship.

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

Apparently the rise of consciousness is linked to certain kinds of privation. It is the bitterness of self-consciousness that we knowers know best. Critical of the illusions that sustained mankind in earlier times, this self-consciousness of ours does little to sustain us now. The question is: which is disenchanted, the world itself or the consciousness we have of it?

Social Democratic centralism cannot be based on the mechanical subordination and blind obedience of the party membership to the leading party center. The Social Democratic movement cannot allow the erection of an air-tight partition between the class-conscious nucleus of the proletariat already in the party and its immediate popular environment, the nonparty sections of the proletariat.

Man is as much a slave to his immediate surroundings now as he was when he lived in tree-huts. Give him the highest, the most exciting thoughts about man's place in the universe, the meaning of history; they can all be snuffed out in a moment if he wants his dinner, or feels irritated by a child squalling on a bus. He is bound by pettiness.

Christianity taught only what the whole of Asia knew already long before and even better.

What we really long for after death is to go on living this life, this same mortal life, but without its ills without its tedium, and without death. Seneca, the Spaniard, gave expression to this in his Consolatio ad Marciam... And what but that is the meaning of that comic conception of the eternal recurrence which issued from the tragic soul of poor Nietzsche, hungering for concrete and temporal immortality?

Consider all that you've gone through, all that you've survived. And that the story of your life is done, your assignment complete. How many good things have you seen? How much pain and pleasure have you resisted? How many honors have you declined? How many unkind people have you been kind to?

Cunning and deceit will every time serve a man better than force to rise from a base condition to great fortune.

And wonderful it is to see how the Ideal or Soul, place it in what ugliest Body you may, will irradiate said Body with its own nobleness; will gradually, incessantly, mould, modify, new-form or reform said ugliest Body, and make it at last beautiful, and to a certain degree divine!

Philosophy offers an antidote to melancholy. And many still believe in the depth of philosophy!

Lying and guile need only to be revealed and recognized to be undone. When once lying is recognized as such, it needs no second stroke; it falls of itself and vanishes in shame.

The late philosopher Morris R. Cohen of CCNY was asked by a student in the metaphysics course, "Professor Cohen, how do I know that I exist?" The keen old prof replied, "And who is asking?"

The good is the everlasting, the pinnacle of our life. ... life is striving towards the good, toward God. The good is the most basic idea ... an idea not definable by reason ... yet is the postulate from which all else follows. But the beautiful ... is just that which is pleasing. The idea of beauty is not an alignment to the good, but is its opposite, because for most part, the good aids in our victory over our predilections, while beauty is the motive of our predilections. The more we succumb to beauty, the further we are displaced from the good. ...the usual response is that there exists a moral and spiritual beauty ... we mean simply the good. Spiritual beauty or the good, generally not only does not coincide with the typical meaning of beauty, it is its opposite.

In living bodies, how all the various limbs harmonize, and mutually combine, for common defence against injury! What can be more heterogeneous, and unlike, than the body and the soul? and yet with what strong bonds nature has united them, is evident from the pang of separation. As life itself is nothing else but the concordant union of body and soul, so is health the harmonious cooperation of all the parts and functions of the body.
