Humour is the describing the ludicrous as it is in itself; wit is the exposing it, by comparing or contrasting it with something else. Humour is, as it were, the growth of nature and accident; wit is the product of art and fancy.
William HazlittWant of principle is power. Truth and honesty set a limit to our efforts, which impudence and hypocrisy easily overleap.
