is requir'd the highest Stretch of Philosophy to establish so extraordinary a Paradox. To the most careless Observer, there appear to be such Dispositions as Benevolence and Generosity; such Affections as Love, Friendship, Compassion, Gratitude. These Sentiments have their Causes, Effects, Objects, and Operations, markt by common Language and Observation, and plainly distinguish'd from the selfish Passions. And as this is the obvious Appearance of Things, it must be admitted; till some Hypothesis be discover'd, which, by penetrating deeper into human Nature, may prove the former Affections to be Nothing but Modifications of the latter. All Attempts of this Kind have hitherto prov'd fruitless, and seem to have proceeded entirely from that Love of Simplicity, which has been the Source of much false Reasoning in Philosophy. I shall not here enter into any Detail on the present Subject. Many able Philosophers have shown the Insufficiency of these Systems. And I shall take for granted what, I believe, the smallest Reflection will make evident to every impartial Enquirer.
But the Nature of the Subject furnishes the strongest Presumption, that no better System will ever, for the future, be invented, to account for the Origin of the benevolent from the selfish Affections, and reduce all the various Emotions of the human Mind to a per-fect.
