“A sense of humor. Back to Webster's Unabridged: humor is defined as ‘The mental faculty of discovering, expressing, or appreciating ludicrous or absurdly incongruous elements in ideas, situations, happenings, or acts...’ or ‘A changing and uncertain state of mind…’ The organizer searching with a free and open mind void of certainty, hating dogma, finds laughter not just a way to maintain his sanity but also a key to understanding life. Essentially, life is a tragedy; and the converse of tragedy is comedy. One can change a few lines in any Greek tragedy and it becomes a comedy, and vice versa. Knowing that contradictions are the signposts of progress he is ever on the alert for contradictions. A sense of humor helps him identify and make sense out of them. Humor is essential to a successful tactician, for the most potent weapons known to mankind are satire and ridicule. A sense of humor enables him to maintain his perspective and see himself for what he really is: a bit of dust that burns for a fleeting second. A sense of humor is incompatible with the complete acceptance of any dogma, any religious, political, or economic prescription for salvation. It synthesizes with curiosity, irreverence, and imagination. The organizer has a personal identity of his own that cannot be lost by absorption or acceptance of any kind of group discipline organization. I now begin to understand what I stated somewhat intuitively in Reveille for Radicals almost 20 years ago, that ‘the organizer in order to be part of all can be part of none.’”
Saul Alinsky Rules for Radicals [he’s listing the ideal elements for an organizer and I found the notion that left-wing radicals are consistently marked by a good sense of humour especially about themselves was itself so funny it was worth quoting].
