Other passions are afterwards confounded with them. There is always a mixture of love or tenderness with pity, and of hatred or anger with malice.

Context

“On the contrary, when we compare the sentiments of others to our own, we feel a sensation directly opposite to the original one, viz. a joy from the grief of others, and a grief from their joy. But these are only the first foundations of the affections of pity and malice. Other passions are afterwards confounded with them. There is always a mixture of love or tenderness with pity, and of hatred or anger with malice. But it must be confessed, that this mixture seems at first sight to be contradictory to my system. For as pity is an uneasiness, and malice a joy, arising from the misery of others, pity should naturally, as in all other cases, produce hatred; and malice, love.” source
