I have always preferred cheerfulness to mirth. The latter I consider as an act, the former as an habit of mind. Mirth is short and transient, cheerfulness fixed and permanent. Those are often raised into the greatest transports of mirth who are subject to the greatest depressions of melancholy. On the contrary, cheerfulness, though it does not give the mind such an exquisite gladness, prevents us from falling into any depths of sorrow. Mirth is like a flash of lightning, that breaks through a gloom of clouds, and glitters for a moment; cheerfulness keeps up a kind of daylight in the mind, and fills it with a steady and perpetual serenity.

Joseph Addison (1672-1719) English essayist, poet, statesman

The Spectator, #381, “Cheerfulness and Mirth” (17 May 1712)
