A philosophical position developed by a set of sensible men could collapse when another set of equally sensible men refute it. There are no major philosophers whose ideas have not been refuted several times. Greater the philosopher, more multifarious and intense are the refutations. To establish a philosophical position, the philosopher or his followers and sympathizers have to defend their position again and again with ever increasing vigor. The side that engages in more vigorous argumentation usually wins the philosophical debate irrespective of whether their ideas are based on rational and moral considerations.
