Optimism, Pessimism, Species

According to Leibniz, knowledge that this is the best of all possible worlds redeems human suffering.  However, he does not seem to address one the fundamental, according to the theological tradition of which he is a part, sources of suffering--the divine condemnation of the race to the process of propagation, as recounted in Genesis 3.  In contrast, Schopenhauer does address it, implicitly, at least, in his counterpoint to Leibniz' optimism.   For, the source of his Pessimism--the submission of the Individual to the reproductive Will to Live--reflects one of the consequences of the denial of the existence of Leibniz' deity--the possibility of an escape from that submission via divine salvation.  At the same time, Schopenhauer thus brings into relief that the Species is a cardinal concept even prior to the elevation of it to prominence by Marx and Darwin.
