“I have been doomed to such a dreadful shipwreck: that man is not truly one, but truly two. I say two, because the state of my own knowledge does not pass beyond that point.
Others will follow, others will outstrip me on the same lines; and I hazard the guess that man will be ultimately known for a mere polity of multifarious, incongruous and independent denizens. I, for my part, from the nature of my life, advanced infallibly in one direction and in one direction only. It was on the moral side, and in my own person, that I learned to recognise the thorough and primitive duality of man; I saw that, of the two natures that contended in the field of my consciousness, even if I could rightly be said to be either, it was only because I was radically both; and from an early date, even before the course of my scientific discoveries had begun to suggest the most naked possibility of such a miracle, I had learned to dwell with pleasure, as a beloved daydream, on the
thought of the separation of these elements. If each, I told myself, could be housed in separate identities, life would be relieved of all that was unbearable;
the unjust might go his way, delivered from the aspirations and remorse of his more upright twin; and the just could walk steadfastly and securely on his upward path, doing the good things in which he found his pleasure, and no longer exposed to disgrace and penitence by the hands of this extraneous evil.
It was the curse of mankind that these incongruous faggots were thus bound together—that in the agonised womb of consciousness, these polar twins should be continuously struggling. How, then were they dissociated?”
― Robert Louis Stevenson, The Strange Case of Dr. Jekyll and Mr. Hyde
Chapters 6 - 10
Chapter 6: “I wish to see or hear no more of Dr. Jekyll," he said in a loud, unsteady voice. “I am quite done with that person, and I beg that you will spare me any allusion to one whom I regard as dead."
Dr. Lanyon is speaking to Mr. Utterson. Laynon’s appearance is that of someone who has endured a horrifying event.
Chapter 7: “That is just what I was about to venture to propose," returned the doctor with a smile. But the words were hardly uttered, before the smile was struck out of his face and succeeded by an expression of such abject terror and despair, as froze the very blood of the two gentlemen below.
Mr. Utterson and Enfield are standing in the street having a conversation with Jekyll.
Chapter 8: “Now, sir," said he, “you come as gentle as you can. I want you to hear, and I don’t want you to be heard. And see here, sir, if by any chance he was to ask you in, don’t go."
Poole warns Utterson to be careful. They are outside Jekyll’s locked door – a voice can be heard, but it is not the voice of the doctor.
Chapter 9: “O God! I screamed, and O God! Again and again; for there before my eyes – pale and shaken, and half fainting, and groping before him with his hands, like a man restored from death – there stood Henry Jekyll.
Hyde enters the house looking for a chemical entrusted to Dr. Lanyon. He prepares a concoction, drinks it, and is transformed into Jekyll.
Chapter 10: “Here then, as I lay down the pen and proceed to seal up my confession, I bring the life of that unhappy Henry Jekyll to an end."
Jekyll has unburdened his soul and made confession. He does not know what fate will befall Hyde.
