XXIII.

Envy is hatred, in so far as it induces a man to be pained by another's good fortune, and to rejoice in another's evil fortune.
Explanation--Envy is generally opposed to sympathy, which, by doing some violence to the meaning of the word, may therefore be thus defined: XXIV.

Sympathy (misericordia) is love, in so far as it induces a man to feel pleasure at another's good fortune, and pain at another's evil fortune.
Explanation--Concerning envy see the notes to III.xxiv.
