a surplus of reason would be lethal for the existence

Where can so much void and inexplicability lead? We cling to our living days because the desire to die is too logical, therefore inefficient. If life had at least one argument for itself – one tenable, indestructible argument – it would be torn apart; instincts and prejudices fade when in contact with Rigor. Every living creature feeds on the unexplainable; a surplus of reason would be lethal for the existence – an endeavor to reach the Absurd … Give a precise meaning to life and it will instantaneously lose its savor. The lack of clarity of its goals makes it superior to death; a grain of precision would lower it to the triviality of a tomb. For a positive science dealing with the meaning of life would depopulate the Earth in one single day and no fool would ever succeed in resurrecting the fertile improbability on its surface.
