„A defect, as such, does not imply determinations in any direction. The individual's happiness is in the continuous unfolding of his experience, and also in the fruitfulness of his suffering. The criterion of his happiness is his power and permission to grow into his own self, with all that this involves. This, in turn, depends on other circumstances; the reality or mere ostensibility of his reception; the degree to which he is allowed, together with his defects and inherited birth constellations, to be integrated into his community; and the degree to which the community is permitted to become integrated into what he, the individual, represents.“
