This person once claimed that backgammon was a better game than checkers and that it dated back to Sumeria in 3000 BC. This character had spent several nights alone after his companion, Boone, fell and died while exploring an aircraft wreck carrying Virgin Mary statues. Another tragic event involving this man occurred four years ago when his con-artist father pushed him from an eighth story window resulting in him becoming a paraplegic.  For 10 points, identify this middle-aged survival expert on ABC's Lost who shares his name with the English philosopher that wrote Two Treatises on Government.
