“With every day, and from both sides of my intelligence, the moral and the intellectual, I thus drew steadily nearer to that truth, by whose partial discovery I have been doomed to such a dreadful shipwreck: that man is not truly one, but truly two” (76).
The characters in the novel manifest characteristics of the structural theory of the mind. Mr. Hyde would seem easily recognizable as the id, seeking instant gratification, having an aggressive instinct, and having no moral or social mores that need be followed. He takes pleasure in violence and similar to the death instinct ultimately leads to his own destruction. Dr. Jekyll is then the ego; he is conscious and rational, and is dominated by social principles. He has a difficult time juggling between the demands of the id, represented by Mr. Hyde, and the superego as represented by the proclaimed and implicit morals of Victorian society which prided itself on refinement and goodness, and is shocked by the seeming nonchalance with which Edward Hyde indulges in his debaucheries.Singh, Shubh M, and Subho Chakrabarti. “A study in dualism: The strange case of Dr. Jekyll and Mr. Hyde.” Indian journal of psychiatry vol. 50,3 (2008): 221-3. doi:10.4103/0019-5545.43624
“I have observed that when I wore the semblance of Edward Hyde, none could come near to me at first without a visible misgiving of the flesh. This, as I take it, was because all human beings, as we meet them, are commingled out of good and evil: and Edward Hyde, alone in the ranks of mankind, was pure evil” (79).
