"In its most mature meaning, determinism has nothing to do with passivity, but clarifies the fact that man tends to act, before he wanted to act, and that he wants, before he knows why he wants, because his head is the last and unsurest of his limbs. The best use that a group of men can make of their heads, is to perceive in advance the historical moment, in which they - other than remain passive - for the first time will be hurled into the maelstrom of battle and struggle with their head first."
