Peter's question brings the answer that perhaps the philosophy in question needs elaboration. Any philosophy that can both prove itself, and contradict itself, is fascinating, but needs more attention. Something like that that will receive such attention, and conflicting ideas surrounding it, perhaps can go either way. Such a situation puts the philosophy's credibility into question, but does not discredit it entirely until further thought can be given. The evolution of the idea may not have ended, and there may be new circumstances available to shed light on the particular philosophy.
