Not ordinary people are frequently coocoo for some level. Philosophers (not contemporary) weren't the typical people of their age so he might had been even autist.
However judging a man without the context of the age and place surrounding him can lead us onto the wrong path.
Also maybe he was just overcompensating for something or had a simple OCD.
