"Leontius, the son of Aglaion, was coming up from the Peiraeus, close to the outer side of the north wall, when he saw some dead bodies lying near the executioner, and he felt a desire to look at them, and at the same time felt disgust at the thought, and tried to turn aside. For some time he fought with himself and put his hand over his eyes, but in the end the desire got the better of him, and opening his eyes wide with his fingers he ran forward to the bodies, saying, 'There you are, curse you, have your fill of the lovely spectacle.' "

Augustine, Confessions (Book X, Section 35)

"When the senses demand pleasure, they look for objects of visual beauty, harmonious sounds, fragrant perfumes, and things that are pleasant to the taste or soft to the touch. But when their motive is curiosity, they may look for just the reverse of these things ... from a relish for investigation and discovery. What pleasure can there be in the sight of a mangled corpse, which can only horrify? Yet people will flock to see one lying on the ground, simply for the sensation of sorrow and horror that it gives them."
