People, particularly over-moralistic Americans, have often seen me as a pessimist and humourless to boot, yet I think I have an almost maniacal sense of humour. The problem is that it's rather deadpan.
What we eventually run up against are the forces of humourlessness, and let me assure you that the humourless as a bunch don't just not know what's funny , they don't know what's serious. They have no common sense, either, and shouldn't be trusted with anything.
By calling him humourless I mean to impugn his seriousness, categorically: such a man must rig up his probity ex nihilo .
