Thomas Hobbes Quote
Emulation is grief arising from seeing one's self, exceeded or excelled by his concurrent, together with hope to equal or exceed him in time to come, by his own ability. But envy is the same grief joined with pleasure conceived in the imagination of some ill-fortune that may befall him.
