If to feel envy is to feel bad when another does well, what should we call the emotion of feeling good when another suffers misfortune? There is no word in English for this as far as I know, but in German it is called Schadenfreude. This word is used in English from time to time, and it is one every educated person should know. It means joy (Freude) at another injuries (Schaden). The great Schopenhauer, somewhere in Aphorismen zur Lebensweisheit, remarks that while envy (Neid) is human, Schadenfreude is diabolical.
Exactly right. There is something fiendish in feeling positive glee at another’s misery. This is not to imply that envy is not a hateful emotion to be avoided as far as possible. Invidia, after all, is one of the seven deadly sins. From the Latin invidia comes ‘invidious comparison’ which just means an envious comparison.
My translation of the Italian:
To feel envy is human, but to taste joy at the injury of others is diabolical.
