The only unforgivable crime is to cut short the experiment of one's own life before its natural end. To do so is a weakness and a pity-- for the experiment of life will cut itself off soon enough, in all our cases, and one may just as well have the courage and the curiosity to stay in the battle until one's eventual and inevitable demise. Anything less than a fight for endurance is cowardly. Anything less than a fight for endurance is a refusal of the great covenant of life.
