"Though so profound a double-dealer, I was in no sense a hypocrite. Both sides of me were in dead earnest; I was no more myself when I laid aside restraint and plunged in shame, than when I labored, in the eye of day, at the furtherance of knowledge or the relief of sorrow and suffering." [Robert Louis Stevenson, "The Strange Case of Dr. Jekyll and Mr. Hyde," 1886]
来自英国作家Robert Louis Stevenson的小说《化身博士》,白天以绅士Jekyll的面目出现,晚上以魔鬼Hyde的面目出现,因此引申词义双重人格或人格分裂。参照电影《化身博士》。
