„Invention is the most important product of man's creative brain. The ultimate purpose is the complete mastery of mind over the material world, the harnessing of human nature to human needs.“

„The most important misunderstanding seems to me to lie in a confusion between the human necessities which I consider part of human nature, and the human necessities as they appear as drives, needs, passions, etc., in any given historical period.“

— Erich Fromm German social psychologist and psychoanalyst 1900 - 1980
Context: The most important misunderstanding seems to me to lie in a confusion between the human necessities which I consider part of human nature, and the human necessities as they appear as drives, needs, passions, etc., in any given historical period. This division is not very different from Marx’s concept of "human nature in general", to be distinguished from "human nature as modified in each historical period". The same distinction exists in Marx when he distinguishes between "constant" or "fixed" drives and "relative" drives. The constant drives "exist under all circumstances and … can be changed by social conditions only as far as form and direction are concerned". The relative drives "owe their origin only to a certain type of social organization".

„No feats of heroism are needed to achieve the greatest and most important changes in the existence of humanity“

— Leo Tolstoy Russian writer 1828 - 1910
Context: No feats of heroism are needed to achieve the greatest and most important changes in the existence of humanity; neither the armament of millions of soldiers, nor the construction of new roads and machines, nor the arrangement of exhibitions, nor the organization of workmen's unions, nor revolutions, nor barricades, nor explosions, nor the perfection of aerial navigation; but a change in public opinion. And to accomplish this change no exertions of the mind are needed, nor the refutation of anything in existence, nor the invention of any extraordinary novelty; it is only needful that we should not succumb to the erroneous, already defunct, public opinion of the past, which governments have induced artificially; it is only needful that each individual should say what he really feels or thinks, or at least that he should not say what he does not think. Ch. 17
