And is not this the true end of scholarship? It is to make us wise, of course, but what is the use of being wise if we are not sometimes merry? The merriment of wise men is not the uninformed, gross fun of ignorant men, but it has more kinship with that than the pinched, frightened fun of those who are neither learned nor ignorant, gentle nor simple, bound nor free. The idea that a wise man must be solemn is bred and preserved among people who have no idea what wisdom is, and can only respect whatever makes them feel inferior.
