“There exists [a] word in German, Geschichte, which designates not accomplished history, but history in the present, doubtless determined in large part, yet only in part, by the already accomplished past; for a history which is present, which is living, is also open to a future that is uncertain, unforeseeable, not yet accomplished, and therefore aleatory. Living history obeys only a constant (not a law): the constant of class struggle. Marx did not use the term 'constant', which I have taken from Levi-Strauss, but an expression of genius: 'tendential law', capable of inflecting (but not contradicting) the primary tendential law, which means that a tendency does not possess the form or figure of linear law, but that it can bifurcate under the impact of an encounter with another tendency, and so on ad infinitum. At each intersection the tendency can take a path that is unforeseeable because it is aleatory.”

“Only by taking infinitesimally small units for observation (the differential of history, that is, the individual tendencies of men) and attaining to the art of integrating them (that is, finding the sum of these infinitesimals) can we hope to arrive at the laws of history.”

“There is a thing called knowledge of the world, which people do not have until they are middle-aged. It is something which cannot be taught to younger people, because it is not logical and does not obey laws which are constant. It has no rules. Only, in the long years which bring women to the middle of life, a sense of balance develops…when she is beginning to hate her used body, she suddenly finds that she can do it. She can go on living…”

“But the detail of the poem shows power akin to genius, and reveals to us that much neglected law of literary history -- that potential genius can never become actual unless it finds or makes the Form which it requires.”

“When the economists say that present-day relations – the relations of bourgeois production – are natural, they imply that these are the relations in which wealth is created and productive forces developed in conformity with the laws of nature. These relations therefore are themselves natural laws independent of the influence of time. They are eternal laws which must always govern society. Thus, there has been history, but there is no longer any.”

“The laws of history are as absolute as the laws of physics, and if the probabilities of error are greater, it is only because history does not deal with as many humans as physics does atoms, so that individual variations count for more.”
