He that is not on my side is against me, and he that does not gather with me scatters.

There always comes a time in history when the person who dares to say that 2+2=4 is punished by death. And the issue is not what reward or what punishment will be the outcome of that reasoning. The issue is simply whether or not 2+2=4.

Much must also be withdrawn into oneself: for a well-composed conversation of differences disturbs and renews the affections, and infuriates whatever is weak in the mind and has not been cared for...Loneliness will cure the hatred of the crowd, the boredom of solitude will be cured by the crowd.... A certain dullness and languor of the mind is born from constant toil....Nor would the desire of men so much tend to this, unless play and fun had a kind of natural voluptuousness. The frequent use of which will relieve all the weight of the soul and all the vigor.For sleep is also necessary for refreshment, but if you continue it day and night, death will result.

You could attach prices to ideas. Some cost a lot some little. ... And how do you pay for ideas? I believe: with courage.

To-day is the parent of to-morrow. The present casts its shadow far into the future. That is the law of life, individual and social. Revolution that divests itself of ethical values thereby lays the foundation of injustice, deceit, and oppression for the future society. The means used to prepare the future become its cornerstone.

There is needed, no doubt, a body of servants (ministerium) of the invisible church, but not officials (officiales), in other words, teachers but not dignitaries, because in the rational religion of every individual there does not yet exist a church as a universal union (omnitudo collectiva).

All his life he [the American] jumps into the train after it has started and jumps out before it has stopped; and he never once gets left behind, or breaks a leg.

Are designations congruent with things? Is language the adequate expression of all realities? It is only by means of forgetfulness that man can ever reach the point of fancying himself to possess a "truth" of the grade just indicated. If he will not be satisfied with truth in the form of tautology, that is to say, if he will not be content with empty husks, then he will always exchange truths for illusions.

Love of the absolute engenders a predilection for self-destruction. Hence the passion for monasteries and brothels. Cells and women, in both cases. Weariness with life fares well in the shadow of whores and saintly women.

Brother will betray brother to death, and a father his child. Children will even rise up against their parents and have them put to death.

To live life well is to express life poorly; if one expresses life too well, one is living it no longer.

Let us go on committing suicide by working among our people, and let them dream life just as the lake dreams the sky.

I do not think that any civilization can be called complete until it has progressed from sophistication to unsophistication, and made a conscious return to simplicity of thinking and living, and I call no man wise until he has made the progress from the wisdom of knowledge to the wisdom of foolishness, and become a laughing philosopher, feeling first life's tragedy and then life's comedy. For we must weep before we can laugh. Out of sadness comes the awakening, and out of the awakening comes the laughter of the philosopher, with kindliness and tolerance to boot.

The pornographic face says nothing. It has no expressivity or mystery.

How can this cosmic religious experience be communicated from man to man, if it cannot lead to a definite conception of God or to a theology? It seems to me that the most important function of art and of science is to arouse and keep alive this feeling in those who are receptive.

Impenetrable in their dissimulation, cruel in their vengeance, tenacious in their purposes, unscrupulous as to their methods, animated by profound and hidden hatred for the tyranny of man - it is as though there exists among them an ever-present conspiracy toward domination, a sort of alliance like that subsisting among the priests of every country.

Strictly speaking, the mass, as a psychological fact, can be defined without waiting for individuals to appear in mass formation. In the presence of one individual we can decide whether he is "mass" or not. The mass is all that which sets no value on itself - good or ill - based on specific grounds, but which feels itself "just like everybody," and nevertheless is not concerned about it; is, in fact, quite happy to feel itself as one with everybody else.

Since those who rule in the city do so because they own a lot, I suppose they're unwilling to enact laws to prevent young people who've had no discipline from spending and wasting their wealth, so that by making loans to them, secured by the young people's property, and then calling those loans in, they themselves become even richer and more honored.

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

One may be humble out of pride.

It is an odd fact that anyone who wishes to start a war must always make it appear that he is fighting in a just cause even if the real motive is naked aggression. Fortunately for the would-be aggressor, a "just cause" is very easy to find.

What, then, is the animal? First of all, a system of plant-souls. The unity of those plant-souls, which unity nature itself produces, is the soul of the animal. Its world is therefore partly that of the plants - its nourishment, for instance, it receives partly through synthesis from vegetable, and through analysis from animal nature - and partly that of the animals, whereof we shall speak directly. Each product of nature is an organically in-itself completed totality in space, like the plant. Hence, the unknown x which we are looking for must also be such a whole or totality, and in so far it must also have a principle of organization, a sphere and central point of this organization ; in short, the same which we have called the soul of the plant, which thus remains common to both. ... The animal is a system of plant-souls, and the plant is a separated, isolated part of an animal. Both reciprocally affect each other.

Might is a fine thing, and useful for many purposes; for 'one goes further with a handful of might than with a bagful of right'. You long for freedom? You fools! If you took might, freedom would come of itself. See, he who has might 'stands above the law'. How does this prospect taste to you, you 'law-abiding' people? But you have no taste!

The modern proletarian class doesn't carry out its struggle according to a plan set out in some book or theory; the modern workers' struggle is a part of history, a part of social progress, and in the middle of history, in the middle of progress, in the middle of the fight, we learn how we must fight... That's exactly what is laudable about it, that's exactly why this colossal piece of culture, within the modern workers' movement, is epoch-defining: that the great masses of the working people first forge from their own consciousness, from their own belief, and even from their own understanding the weapons of their own liberation.

Old religious factions are volcanoes burnt out.

The bourgeois public sphere may be conceived above all as the sphere of private people come together as a public; they soon claimed the public sphere regulated from above against the public authorities themselves, to engage them in a debate over the general rules governing relations in the basically privatized but publicly relevant sphere of commodity exchange and social labor.

I do not know but it is too much to read one newspaper a week. I have tried it recently, and for so long it seems to me that I have not dwelt in my native region. The sun, the clouds, the snow, the trees say not so much to me. You cannot serve two masters. It requires more than a day's devotion to know and to possess the wealth of a day.

Man is always something more than what he knows of himself. He is not what he is simply once and for all, but is a process...

I have heard with admiring submission the experience of the lady who declared "that the sense of being perfectly well-dressed gives a feeling of inward tranquility which religion is powerless to bestow".

People have committed suicide because of their failure to realize the passions for love, power, fame, revenge. Cases of suicide because of a lack of sexual satisfaction are virtually nonexistent.

The passion of laughter is nothing else but a sudden glory arising from sudden conception of some eminency in ourselves, by comparison with the infirmities of others, or with our own formerly...

The immediate aim of the Communists is the same as that of all the other proletarian parties: Formation of the proletariat into a class, overthrow of the bourgeois supremacy, conquest of political power by the proletariat.

Our bodies are perishable, wealth is not at all permanent and death is always nearby. Therefore we must immediately engage in acts of merit.

Let men be happy, informed, skillful, well behaved, and productive.

Emptiness is not a denial of the proper but an affirmation of it.

Seek, therefore, thyself! But in finding oneself, does not one find one's own nothingness? ...Carlyle answers (Past and Present, book iii, chap. xi.). "The latest Gospel in the world is, Know thy work and do it. Know thyself: long enough has that poor self of thine tormented thee; thou wilt never get to know it, I believe! Think it thy business, this of knowing thyself; thou art an unknowable individual: know what thou canst work at; and work at it, like Hercules. That will be thine better plan." ...and what is my work? - without thinking about myself, is to love God. ...And on the other hand, in loving God in myself, am I not loving myself more than God, am I not loving myself in God?

I shall cheerfully bear the reproach of having descended below the dignity of history if I can succeed in placing before the English of the nineteenth century a true picture of the life of their ancestors.

What the rest of us see only under the influence of mescalin, the artist is congenitally equipped to see all the time. His perception is not limited to what is biologically or socially useful.

The finest workers in stone are not copper or steel tools, but the gentle touches of air and water working at their leisure with a liberal allowance of time.

All religions so far have been the expression of historical stages of development of individual peoples or groups of peoples. But communism is the stage of historical development which makes all existing religions superfluous and brings about their disappearance.

Let the eye of vigilance never be closed.

To be sure, risks abound; but no one is proposing compassionate stewardship of ecosystems by philosophers. Humans are capable of choosing our own future pain-sensitivity too; but any species-wide genomic shift in human pain tolerance will depend on the willingness of prospective parents to use preimplantation genetic screening.

I was forced, through seeing the error of their foundation, to abandon all belief in every religion which had been taught to man. But my religious feelings were immediately replaced by the spirit of universal charity - not for a sect, or a party, or for a country or a colour - but for the human race, and with a real and ardent desire to do good.
