Dr Jekyll and Mr Hyde, are they one? Or does it really show the twofold of a human’s nature?
Jekyll had been born wealthy and had grown up handsome, honourable, and distinguished, and yet, he committed secret acts of which he was thoroughly ashamed; intellectually, he evaluated the differences between his private life and his public life and, ultimately, he became obsessed with the idea that at least two different entities, or perhaps even more, occupy a person's body. His reflections and his scientific knowledge led him to contemplate the possibility of scientifically isolating these two separate components. With this in mind, he began to experiment with various chemical combinations. Having ultimately compounded a certain mixture, he then drank it, and his body, under great pain, was transformed into an ugly, repugnant, repulsive "being," representing the "pure evil" that existed within him. Afterward, by drinking the same potion, he could then be transformed back into his original self. His evil self became Edward Hyde, and in this disguise, he was able to practice whatever shameful depravities he wished, without feeling the shame that Dr. Jekyll would feel. Recognizing his two "selves," Jekyll felt the need of providing for, and protecting, Edward Hyde .Many critics are not content to interpret the novel as a conflict between good (Jekyll) and evil (Hyde), but, instead, the novel points out, according to them, that evil (represented by Hyde) is only a small portion of man, a portion represented by Hyde's diminutive and dwarfish size. Certainly, Dr. Jekyll implies this when he theorizes that "man will be ultimately known for a mere polity of multifarious, incongruous, and independent denizens"--that is, evil and good and many other qualities will ultimately be found to make up the entire man. Enfield, describing Hyde to Utterson, "There is something wrong with his appearance; something displeasing, something downright detestable." This shows the first implication of Mr Hyde.
So is any human part good and part evil? Is there an urge to always do badly? Nevertheless no one is actually perfect… Jekyll, reflecting on mankind, "All human beings... are commingled out of good and evil."
In the novel something unusual happens the setting changes as something ghastly about to happen often in the form of Mr Hyde” The ni9ght got darker and the moon got paler”. This signifies Mr Hyde is about to come and cause havoc. Again the setting correlates to the character
Thus, Jekyll's enjoyment of Hyde's activities allows Hyde to grow in stature, and of the two men, Hyde is slowly gaining the ascendancy over Jekyll. The mere fact that Jekyll never gave up the house in Soho (rented for Hyde) nor destroyed Hyde's clothes is proof to us that the vow he made to Utterson in Chapter 5, after the murder of Sir Danvers ("I swear to God I will never set eyes on him again. I bind my honor to you that I am done with him"), was indeed a hypocritical or empty vow. Even though Jekyll did try for two months to lead a "life of such severity," the Hyde in Jekyll was constantly struggling for release. Repressed for so long, when Hyde emerged, he "came out roaring." Jekyll now has to contend with his "lust of evil," with the "damned horrors of the evenings," and with"the ugly face of iniquity" which stared into his soul. Hyde is not to be denied because, secretly, Jekyll still desires his presence and his activities. But he also knows that if he lets "Hyde peep out an instant . . . the hands of all men would be raised to take and slay him." Therefore, Hyde is trapped by his own evil ways and is confined to the laboratory.
However, when Jekyll is sitting peacefully one day in Regent's Park, in broad daylight, he feels all of the symptoms of Hyde emerging without the aid of the chemical potion. Hyde appears because Jekyll, who has so long tried to deny and suppress him, subconsciously desires that he appear again. But the appearance must be concealed, and so Jekyll/Hyde--by now, it is difficult to separate the two--conceive of a plan to get their revenge on Dr. Lanyon, who has so often ridiculed Dr. Jekyll and has refused to even contemplate the possibility of an evil side of his nature existing. Thus, the elaborate scheme involving Lanyon--the letter written by Hyde, but in Jekyll's handwriting--allows Jekyll/Hyde to achieve their revenge against Dr. Lanyon.
From this point on, until Utterson and Poole break down the door, Jekyll/Hyde have an even stranger relationship with each other. Jekyll hates Hyde for the ascendancy that Hyde has over him, and Hyde hates Jekyll both because of Jekyll's hatred, but more importantly because Hyde knows that Jekyll can destroy him (Hyde) by committing suicide as Jekyll. The final irony is that Jekyll is the one who commits suicide (the evil Hyde, of course, would never do this), but during the act of Jekyll's dying, Hyde regains the ascendancy so that Utterson and Poole find not the body of Jekyll, but that of Hyde.
plays only a minor role in the novel’s plot, but his thematic significance extends beyond his brief appearances. When we first encounter him, he speaks dismissively of Jekyll experiments, referring to them as “unscientific balderdash.” His scientific scepticism renders him, to an even greater extent than Utterson, an embodiment of rationalism and a proponent of materialist explanations. As such, he functions as a kind of foil for Jekyll. Both men are doctors, well respected and successful, but they have chosen divergent paths. From Lanyon’s early remarks, we learn that Jekyll shared some of his research with Lanyon, and one may even imagine that they were partners at one point. But Lanyon chooses to engage in rational, materialist science, while Jekyll prefers to pursue what might be called mystical or metaphysical science.
It is appropriate, then, that Lanyon is the first person to see Jekyll enact his transformations—the great advocate of material causes is witness to undeniable proof of a metaphysical, physically impossible phenomenon. Having spent his life as a rationalist and a sceptic, Lanyon cannot deal with the world that Jekyll’s experiments have revealed. Deep within him, Lanyon prefers to die rather than go on living in a universe that, from his point of view, has been turned upside down. After his cataclysmic experience, Lanyon, who has spent his life pursuing knowledge, explicitly rejects the latest knowledge he has gained. “I sometimes think if we knew all,” he tells Utterson, “we should be gladder to get away.” With these words, Lanyon departs from the novel, his uncompromising rationalism ceding to the inexplicable reality of Jekyll.
Although witnesses a string of shocking events, Utterson himself is a largely unexciting character and is clearly not a man of strong passions or sensibilities. Indeed, Stevenson intends for him to come across in this way: from the first page of the novel, the text notes that Utterson has a face that is “never lighted by a smile,” that he speaks very little, and that he seems “lean, long, dusty, and dreary.” Yet, somehow, he is also “lovable,” and dull and proper though he may be, he has many friends. His lovability may stem from the only interesting quality that Stevenson gives him—namely, his willingness to remain friends with someone whose reputation has suffered. This loyalty leads him to plumb the mystery that surrounds Jekyll. Utterson represents the perfect Victorian gentleman. He consistently seeks to preserve order and decorum, does not gossip, and guards his friends’ reputations as though they were his own. Even when he suspects his friend Jekyll of criminal activities such as blackmail or the sheltering of a murderer, he prefers to sweep what he has learned—or what he thinks he has learned—under the rug rather than bring ruin upon his good friend. Utterson’s status as the epitome of Victorian norms also stems from his devotion to reason and common sense. He investigates what becomes a supernatural sequence of events but never allows himself to even entertain the notion that something uncanny may be going on. He considers that misdeeds may be occurring but not that the mystical or metaphysical might be afoot. Thus, even at the end, when he is summoned by to Jekyll home and all the servants are gathered frightened in the hallway, Utterson continues to look for an explanation that preserves reason. He desperately searches for excuses not to take any drastic steps to interfere with Jekyll’s life. In Utterson’s devotion to both decorum and reason, Stevenson depicts Victorian society’s general attempt to maintain the authority of civilization over and against humanity’s darker side. Stevenson suggests that just as Utterson prefers the suppression or avoidance of revelations to the scandal or chaos that the truth might unleash, so too does Victorian society prefer to repress and deny the existence of an uncivilized or savage element of humanity, no matter how intrinsic that element may be.
Yet, even as Utterson adheres rigidly to order and rationality, he does not fail to notice the uncanny quality of the events he investigates. Indeed, because we see the novel through Utterson’s eyes, Stevenson cannot allow Utterson to be too unimaginative—otherwise the novel’s eerie mood would suffer. Correspondingly, Stevenson attributes nightmares to Utterson and grants him ominous premonitions as he moves through the city at night—neither of which seem to suit the lawyer’s normally reasonable personality, which is rarely given to flights of fancy. Perhaps, the novel suggests, the chilling presence of Hyde in London is strong enough to penetrate even the rigidly rational shell that surrounds Utterson, planting a seed of supernatural dread.
Good and evil mostly come in pairs – without good there is no evil, without evil there is no good. It is the temperament of mankind this relates to Dr Jekyll and Mr Hyde. There is probably always a little bit of evil in all of us and it is in our own state of mind (choice) to choose if to that or do that. This is what Dr Jekyll experienced.
