Novelist, Playwright and prolific essay writer the late Gore Vidal, (1925 - 2012)1 could always be counted on for a provocative opinion or two or three. He was also sure to slay the sacred cows of received opinion with his incisive wit. Even if you disagree with him his opinions on literary matters, politics, history, social issues etc., were usually well grounded and if not that at least interesting.
It is however sad to say that late in life Gore Vidal developed a severe case of conspiracy theory thinking. This served to bring his whole oeuvre into disrepute by enabling his critics to label him a crack pot.
