“Having acknowledged that between each and every of them there is, beyond and above all individual differences, a certain consent of intellects, and that a permanent secludedness separates them from all things around them that are passed for a life of intellect, the signatories, in the present conditions, have found it a necessity to underscore with particular accuracy what they all hold in common, as well as to engage in a more disciplined collective activity, for which each of them agrees to sacrifice the psychological side of his own “I”. They are resolved, even in the unfathomable dialectical moments of that very activity, to make the movement of their continual ideological and moral redefining constant and irreducible. This publication, the first jointly produced by them, represents only one visible moment in emphasising the issue of this redefining that we perceive as indispensable.”
