There is a kind of courtesy in scepticism. It would be an offence against polite conventions to press our doubts too far and question the permanence of our estates, our neighbours’ independent existence, or even the justification of a good bishop’s faith and income. Against metaphysicians, and even against bishops, sarcasm was not without its savour; but the line must be drawn somewhere by a gentleman and a man of the world.

George Santayana (1863-1952) Spanish-American poet and philosopher [Jorge Agustín Nicolás Ruíz de Santayana y Borrás]
