If yon wish to be like the gods on earth, to be free in the realms of the dead, pluck not the fruit from the garden! In appearance it may glisten to the eye; but the perishable pleasure of possession quickly avenges the curse of curiosity.
Friedrich SchillerLet him that sows the serpent's teeth not hope to reap a joyous harvest. Every crime has, in the moment of its perpetration, its own avenging angel,--dark misgivings at the inmost heart.
Friedrich SchillerOne drop of hatred left in the cup of joy turns the most blissful draught into poison.
