Wittgenstein was a terrible person who hit children, hard, on the head:<p><a href="http://en.wikipedia.org/wiki/Ludwig_Wittgenstein" rel="nofollow">http://en.wikipedia.org/wiki/Ludwig_Wittgenstein</a><p>> His severe disciplinary methods (often involving corporal punishment, not unusual at the time)—as well as a general suspicion amongst the villagers that he was somewhat mad—led to a long series of bitter disagreements with some of his students' parents, and eventually culminated in April 1926 in the collapse of an eleven-year-old boy whom Wittgenstein had struck on the head.[29] The boy's father attempted to have Wittgenstein arrested, and despite being cleared of misconduct, he resigned his position and returned to Vienna, feeling that he had failed as a school teacher.<p>But Wittgenstein was a much worse philosopher. He wrote, for example, confusing/obscure attacks on the value of philosophy itself. Not having any philosophical problems one is interested in or finds fruitful is completely understandable. And of course a person in that situation won't make any useful contributions to solving philosophical problems. The weird thing is why he's considered a philosopher, let alone a good one, by anyone.
