T 2.2.9.4

This hypothesis is founded on sufficient experience. A man, who from any motives has entertain'd a resolution of performing an action, naturally runs into every other view or motive, which may fortify that resolution, and give it authority and influence on the mind. To confirm us in any design, we search for motives drawn from interest, from honour, from duty. What wonder, then, that pity and benevolence, malice, and anger, being the same desires arising from different principles, shou'd so totally mix together as to be undistinguishable? As to the connexion betwixt benevolence and love, anger and hatred, being original and primary, it admits of no difficulty.
