One kills oneself because life is not worth living, that is certainly a truth yet an unfruitful one because it is a truism.

Context

“In truth, there is no necessary common measure between these two judgments. One merely has to refuse to he misled by the confusions, divorces, and inconsistencies previously pointed out. One must brush everything aside and go straight to the real problem. One kills oneself because life is not worth living, that is certainly a truth yet an unfruitful one because it is a truism. But does that insult to existence, that flat denial in which it is plunged come from the fact that it has no meaning? Does its absurdity require one to escape it through hope or suicide—this is what must be clarified, hunted down, and elucidated while brushing aside all the rest.” source
