For pride and humility are pure emotions in the soul, unattended with any desire, and not immediately exciting us to action.

But love and hatred are not compleated within themselves, nor rest in that emotion, which they produce, but carry the mind to something farther.

Love is always followed by a desire of the happiness of the person beloved, and an aversion to his misery: As hatred produces a desire of the misery and an aversion to the happiness of the person hated.

So remarkable a difference betwixt these two sets of passions of pride and humility, love and hatred, which in so many other particulars correspond to each other, merits our attention.
The conjunction of this desire and aversion with love and hatred may be accounted for by two different hypotheses.

The first is, that love and hatred have not only a cause, which excites them, viz, pleasure and pain; and an object, to which they are directed, viz, a person or thinking being; but likewise an end, which they endeavour to attain, viz, the happiness or misery of the person beloved or hated; all which views, mixing together, make only one passion.
