Camus called this kind of leap of faith ‘philosophical suicide,’ or what happens when the absurdity (meaninglessness) of existence is overwhelming, compelling one to resort to the pre-fabricated structure of religion or ideology to provide purpose and meaning. Once this is done, once a particular belief is locked in, the mind closes like a steel trap, and all further philosophical and theological inquiry is over. That leap of faith is philosophical suicide. Doing this offers an escape from the nagging doubts that everything we do is ultimately meaningless and the universe without purpose.
