Will, Self-Preservation, Magnanimity

For Spinoza, there are two main species of Virtue--Courage, the effort to preserve one's being, and Magnanimity, the effort to aid and befriend others. However, this concept of Magnanimity seems inconsistent with his principle that all behavior is an effort to preserve one's being. For, on the basis of the latter, generosity seems reducible to a means to self-preservation, and, hence, does not seem to merit the distinction of being 'high'-minded. In contrast, here, Magnanimity is not fundamentally problematic in the context of self-oriented behavior, because the fundamental personal principle is not Self-Preservation, but Evolvement, i. e. growth. So, since Evolvement entails Will, the extending of oneself towards others, Magnanimity is co-extensive with the fundamental personal conatus, and is not, as it is for Spinoza, a problematic surd for the system.
