Defining Good in Abstraction
What good actually is might best be described as that which within oneself generates positive externalities outside oneself which has a greater tendency to promote the same form of positive externalities amongst those experiencing the initial externality than it would to promote negative externalities amongst the same individuals, as the initial externality ripples through both time and space. One draw back of this description is that it implies that good is dependent upon an intangible relation to and existence of others. A being thus cannot be good in and of it self but rather must be contrasted with that of another being in determinations of good. This unfortunately does not seem to be avoidable. The level of abstraction here is such that it may be easier to merely consider it, indefinable for brevity as G.E. Moore puts it, and it is certainly in and of itself, un-analyzable.
