Albert Camus said this quote

Let us seek the respite where it is—in the very thick of battle. For in my opinion, and this is where I shall close, it is there. Great ideas, it has been said, come into the world as gently as doves. Perhaps then, if we listen attentively, we shall hear, amid the uproar of empires and nations, a faint flutter of wings, the gentle stirring of life and hope. Some will say that this hope lies in a nation; others, in a man. I believe rather that it is awakened, revived, nourished by millions of solitary individuals whose deeds and works every day negate frontiers and the crudest implications of history. As a result, there shines forth fleetingly the ever threatened truth that each and every man, on the foundation of his own suffering and joys, builds for all.
