“One should be under no illusions as to the future of the Old World. The real contest in the present day is purely social.”

The Historical Illuminatus as spoken by Sigismundo Celine
Context: The illusion of Sin and Guilt, the madness of our species, is the act of cursing the world under the misapprehension that one is cursing only one part of it. To curse the fig tree, as in the funniest and most misunderstood parable of Jesus, is to curse the soil in which it grew, the seed, the rains, the sun; the whole world, eventually — because no part is truly separate from the whole. The fallacy is that one can judge the part in isolation from the whole is "the Lie that all men believe."

Progress, Coexistence and Intellectual Freedom (1968), The Basis for Hope, Peaceful Competition
Context: Without socialism, bourgeois practices and the egotistical principle of private ownership gave rise to the "people of the abyss" described by Jack London and earlier by Engels.
Only the competition with socialism and the pressure of the working class made possible the social progress of the twentieth century and, all the more, will insure the now inevitable process of rapprochement of the two systems. It took socialism to raise the meaning of labor to the heights of a moral feat. Before the advent of socialism, national egotism gave rise to colonial oppression, nationalism, and racism. By now it has become clear that victory is on the side of the humanistic, international approach.
The capitalist world could not help giving birth to the socialist, but now the socialist world should not seek to destroy by force the ground from which it grew. Under the present conditions this would be tantamount to the suicide of mankind. Socialism should ennoble that ground by its example and other indirect forms of pressure and then merge with it.
