While the individual man is an insoluble puzzle, in the aggregate he becomes a mathematical certainty. You can, for example, never foretell what any one man will be up to, but you can say with precision what an average number will be up to. Individuals vary, but percentages remain constant. So says the statistician.
The liberty of a people consists in being governed by laws which they have made themselves, under whatsoever form it be of government; the liberty of a private man, in being master of his own time and actions, as far as may consist with the laws of God and of his country.
All science, even the divine science, is a sublime detective story. Only it is not set to detect why a man is dead; but the darker secret of why he is alive.
