" One has to fight against the current; to battle every day and every hour against exhaustion, hunger, cold and the resulting inertia; to resist enemies and have no pity for rivals; to sharpen one's wits, build up one's patience, strengthen one's will-power. Or else to throttle all dignity and kill all conscience, to climb down into the arena as a beast against other beasts, to let oneself be guided by those unexpected subterranean forces which sustain families and individuals in cruel times. Many were the ways devised and put into effect by us in order not to die : as many as there are different human characters. All implied a weakening struggle of one against all, and a by no means small sum of aberrations and compromises. Survival without renunciation of any part of one's own moral world - apart from powerful and direct interventions by fortune - was conceded only to very few superior individuals, made of the stuff saints and martyrs.
