 perhaps the Difficulty of accounting for these Effects of Usefulness, or its contrary, has kept Philosophers from admitting them into their Systems of Ethics, and has induc'd them rather to employ any other Principle, in explaining the Origin of moral Good and Evil. But 'tis no just Reason for rejecting any Principle, confirm'd by Experience, that we can give no satisfactory Account of its Origin, nor are able to resolve it into other more general Principles. And if we would employ a little Thought on the present Subject, we need be at no Loss to account for the Influence of Utility, and to deduce it from Principles, the most known and avow'd in human Nature.
