Consider how, even in the meanest sorts of Labour, the whole soul of a man is composed into a kind of real harmony, the instant he sets himself to work! Doubt, Desire, Sorrow, Remorse, Indignation, Despair itself, all these like helldogs lie beleaguering the soul of the poor dayworker, as of every man: but he bends himself with free valour against his task, and all these are stilled, all these shrink murmuring far off into their caves. The man is now a man. The blessed glow of Labour in him, is it not as purifying fire, wherein all poison is burnt up, and of sour smoke itself there is made bright blessed flame!
Thomas Carlyle
