Context

“Only as the result of this knowledge can the will transcend itself, and thereby end the suffering which is inseparable from its manifestation. It is quite impossible to accomplish this end by physical force, as by destroying the germ, or by killing the new-born child, or by committing suicide. Nature guides the will to the light, just because it is only in the light that it can work out its salvation. Therefore the aims of Nature are to be promoted in every way as soon as the will to live, which is its inner being, has determined itself. There is a species of suicide which seems to be quite distinct from the common kind, though its occurrence has perhaps not yet been fully established.” source
