: is it not a historicity proper to man, one inscribed in the very depths of his being, that enables him to adapt himself like any living being, and to evolve like any living being (though with the help of tools, techniques, and organizations belonging to no other living being), that enables him to invent forms of production, to stabilize, prolong, or abridge the validity of economic laws by means of the consciousness he attains of them and by means of the institutions he constructs upon or around them, and that enables him to exercise upon language, with every word he speaks, a sort of constant interior pressure which makes it shift imperceptibly upon itself at any given moment in time.
