Laurence Olivier

The office of drama is to exercise, possibly to exhaust, human emotions. The purpose of comedy is to tickle those emotions into an expression of light relief; of tragedy, to wound them and bring the relief of tears. Disgust and terror are the other points of the compass.

If a man made himself an expert in any particular branch of human activity, there would result the strong tendency that a peculiar aptitude towards the same branch would be found among some of his descendants.
