Species, Unity, Harmony

That a Species is the underlying Unity of its members does not imply that a pre-established harmony obtains in it, for two main reasons.  First, unlike that of Leibniz' deity, the scope of that Unity is not universal, so external factors, e. g. drought, can disrupt internal cohesion, e. g. scarcity can breed conflict.  Second, also unlike that deity, the Species is not eternal, but, rather, is a developing phenomenon, one aspect of which can be improvement in internal organization.  A new Political Philosophy can be the articulation of such an improvement.  In other words, Harmony in the Species is not given, but can be an accomplishment.
