How does Stevenson explore duality in The Strange Case of Dr Jekyll and Mr Hyde? Essay

The idea of duality, in this case, of people displaying duality of character, being â€Å"two faced†, of showing contrasting sides to a person, was of much interest to people in the late 19th century, due to the way it reflected upon their society, and was a key concept of Gothic literature written at the time. In this essay, I shall see how Stevenson explores this, the techniques and methods he uses, and the way in which he shows us how duality is significant in Victorian society. The Strange Case of Dr Jekyll and Mr Hyde was one of the first novels to re-introduce the Gothic literary genre, and thus has several elements that are common to other Gothic novels, which I shall explore in this chapter. With Gothicism being a genre of horror fiction, almost all Gothic novels have some kind of monster as the antagonist. Mr Hyde, although generally regarded as human (a point which I will explore further later on), is quite obviously a monster in the original sense, that is, a being of pure evil and sadism. He is described as a repulsive, grotesque person, for example, by Mr Enfield: â€Å"There is something wrong with his appearance; something displeasing, something downright detestable †¦ he gives a strong feeling of deformity, although I couldn’t specify the point.† The fact that his features are not truly described, but only hinted on vaguely, is also important; it is common for Gothic literature to prey upon the fear of the unknown. Hyde as a monster is only ever witnessed through the eyes of others’, in other words, at no point in the novel do we get an explanation from his viewpoint. This is also another Gothic technique, designed to de-humanise the monster: if we could see things from it’s perspective, we could sympathise with it, therefore this is not allowed. In this novel, the idea of a monster is combined with another Gothic element: the double. The double is the idea of duality taken to an extreme, physical level: a character who has two different forms, often with one being good, the other evil. Common doubles in Gothic literature include werewolves, people who transform from regular humans into a wolf form, and vampires, people who, by night, become blood-sucking monsters. Hyde is the double of Jekyll; although he has a different form, he is not an entirely separate person, but is the evil side of Jekyll. By creating Hyde, Jekyll allows himself to express his innermost desires, without receiving the consequences, such as shame, guilt, or a loss of respect and reputation. This is part of one of the key themes of the book, which is exposing duality in Victorian society, that will be explored later. Finally, there is one thing that sets Jekyll and Hyde apart from other Gothic novels. Usually, they are set in very remote places, often in foreign, Catholic countries. This distances the reader from the often scary events happening, however, in Jekyll and Hyde, the fact that it is set in London makes the events seem much closer and real, and therefore scarier. Other than this minor point, however, it is easy to see how Stevenson uses the Gothic genre to explore duality in the book. Stevenson also uses a particular style of writing and a variety of techniques that help to explore duality, for example, the story is titled as â€Å"The Case of†¦Ã¢â‚¬ , which, as well as being a case as in a particular event, it is in some ways presented almost as a legal case. As the story unfolds, we see Mr Utterson on an investigation, with â€Å"evidence† in the form of accounts from Mr Enfield, the maid and others, as well as various letters and the will made by Dr Jekyll. At the end of the book, we get the full statements of the two main witnesses, Dr Jekyll and Dr Lanyon. As noted before, Mr Hyde’s recollection of the events is never known. By writing in this way, Stevenson clearly shows us contrast between the protagonist â€Å"prosecutor† and the antagonist â€Å"defendant† in the book, as well as involving the other characters as more neutral witnesses, but leaving it open to speculation whether they are in this case necessarily good or bad, exposing their duality, for example with Dr Jekyll, who, although he obviously hates Hyde for his crimes, still continues to crave becoming him for the purposes of expressing his desires. Another technique Stevenson uses is symbolism, mostly in the form of weather, for example, the city streets were filled with smog when Hyde was out, and in chapters 2 and 4, where Utterson and others are trying to find Mr Hyde, there is a thick early-morning fog. This, although common in London at the time, still had associations of secrecy and obscurity, as it was the domain of people like Jack the Ripper, and therefore the perfect setting for the crimes of Mr Hyde. As well as weather, Stevenson used the symbolism of doors and windows also as metaphors for secrecy. For instance, in Jekyll’s laboratory, it is always behind the closed cabinet door that he transforms into Hyde, and it is only when this door is broken down that the mystery is solved. Also, when Utterson and Enfield go to speak with Jekyll in Incident at the Window, the window serves as a barrier between Utterson and the truth that Jekyll hides. To understand how the book as a whole expresses duality, it is important to understand how contemporary readers would have viewed and reacted to the book. Obviously, at the time it was published, readers would have not suspected the idea of transforming into an evil doppelgà ¯Ã‚ ¿Ã‚ ½nger was the key to the mystery about Jekyll and Hyde. We should bear in mind that the most logical solutions are that Jekyll and Hyde were having a homosexual relationship, that Hyde was the illegitimate son of Jekyll, or that Jekyll was somehow being intimidated and controlled by Hyde, possibly via blackmail or debt; contemporary readers would probably have guessed that one of those was the most likely to be the case. It is also important to understand how readers would have viewed Hyde. In the late 19th century, many post-Darwinist theories about evolution and creationism were being discussed and debated, and people were beginning to accept the idea that humans were descended from apes. From this came the idea that people who were socially unacceptable, that is, anyone who did not confirm to the Victorian ideals of etiquette and manners, could be regarded as less evolved, and in a way sub-human. This is highly evident with Mr Hyde, who is described as being very short, deformed and ape-like. There is, however, a final point about the readers of the book, which I regard as one of the most important, and it is what made the book so shocking and controversial at the time. This is the way in which the book exposes the duality that was present in Victorian society, which is displayed by the important characters in the book. Society and culture at the time were based highly on etiquette and conformity, and of appearing the best as possible in public. Any person’s vices were kept behind closed doors, even with close friends and family, and thus, this lead to people leading very separate public and private lives. In Jekyll and Hyde, Stevenson shows this to some extent with all of the major characters, the most significant of which I shall explore further. Mr Utterson seems to be the most single-track, sincere character, however, he does display moral ambivalence as a lawyer. In his own words, â€Å"I let my brother go to the Devil in his own way†. At first, it seems that it is good of him, as a lawyer, to not judge people at all, however, although this seems helpful, it can also be bad, for example it means that he will not step in to help someone who is â€Å"going to the Devil†, but rather let them sort things out in their own way. He only seems to change this at the end of the book, and that is only because Poole suspects that Hyde has murdered Dr Jekyll. Mr Carew, an MP, is clearly shown as being a well-mannered gentlemanly figure, but because of this, we can not help but wonder why he is out in a shady district of London at night, and what he said to anger Mr Hyde so much (if anything). This shows once again the idea of having a private life, kept hidden and separate from your public life, which is what Carew appears to be doing. Finally, there is Dr Jekyll. Throughout the book he is described as a good man, who was respectable, admired by his friends, as someone seen as nearly perfect by Victorian standards. However, beneath the public face we can see that his fascination with Mr Hyde is not purely scientific. Once he has experienced what it is like to be in Hyde’s body, he begins to crave it more, this is because, through Hyde, he can do things that are completely unacceptable, even by modern standards. The book suggests that, as well as murder, he practised many sexual perversions, and similar acts. This shows how a man can fall and become a lesser human, as noted before, and that this is achieved by science. At the time, people believed in the idea that humanity could reach a peak level, and then devolve, becoming ape-like once again, Jekyll and Hyde could be seen as a metaphor for this. As you can see, Stevenson uses these characters effectively as well a wide variety of literary techniques and in the style of a Gothic novel to explore duality and how it relates to society at the time.

Experiential Learning Essay

Growing up in a southern state with traditional family and religious values has made transitioning into college life a bit difficult. Questioning myself and my own bias from my experiences in life is an ongoing process, as I wonder â€Å"is it me? † or its possible that I feel strongly about issues because my values and ethics overshadow all. I feel as if I move from a state of passive to aggressive in my actions just as I do my own state of internal feeling of who I am. Sometimes I feel like I have been treated unfairly both as a child and now, simply for being female. In my actions I sometimes pretend that this does not bother me and that a woman’s place is in the home, being a good mother and wife, bit other times I lash out when this is expected of me from my church, family, and some facets of society. I struggle in this passive aggressive way in my own religion too. As a Baptist, sometimes I feel like the teachings are true and correct and that social issues, such as homosexuality are undesirable and need to be â€Å"fixed†. Other times, however, I feel like homosexuality and other so-called social issues brought up in the church should not be treated like diseases and we have no business trying to â€Å"cure† others. Growing up white, female, and very religious, I was taught ideals that seemed to contradict themselves. The most notable cases were of people in poverty. We were not a poor family, but I would see a great majority of people in my state of Tennessee living in very unpleasant conditions. From teachings of the church and my family, I was taught to help those, who cannot help themselves. But, the irony was that most conservative people around believed that everyone could help themselves and that their state of poverty was simply due to laziness. I remember thinking that I was just a kid and had no control over my home life and that these other impoverished kids I would see could not help their situation any more that I could. So it was confusing that no one seemed to go out of their way (with a few exceptions) to help poor people back home. We were, also, expected to treat people equally and not have any â€Å"hate in our hearts† for anyone for any reason. It wasn’t obvious to my friends and I that our parents were in any way bigoted toward minorities, because they didn’t use racial slurs or openly discuss their dislike for other races. But, when my friends and I started becoming older and noticing boys, our parents wouldn’t hide their shock when we said that we had an attraction for a boy of another race. Then I realized that my parents did not believe in interracial relationships and for awhile I thought that it was not racist, but now I see that my upbringing was all twisted together with racism, sexism, and contempt for the poor and homosexuality. Like many southern girls, I was supposed to find a nice man to marry and going to college was the way to find this man. My family and the society I grew up in had all these expectations of me, hidden agendas, and covert prejudices that I am still trying to understand fully. I want to be treated like an intelligent woman, whose ideas have merit. I get so angry and feel aggressive when people believe that college is just a â€Å"hobby† and that I am here just to find â€Å"Mr. Right†, I am tired of all the years of playing the passive role of the quiet and complacent â€Å"southern belle†. I, also, want to widen my base of friends to include people who do not let religion become a barrier to their lives. Many times from what I have seen in the church, people mindlessly believe what the preacher says and don’t take time to understand that everyone is human and should be treated fairly. I wish I had the courage to go to speak to people, who are homosexual, but I still can’t. This is one of the goals I am working on now.

Using Argument and Persuasion in Writng - Essay Example Even though this story was only the figment of writer Caspian Tredwell-Owens imagination. It is not something that is too far from the reality that we currently face in the fight to prevent the cloning of human beings. The proponents of Human Cloning do so in the name of science. Their stand being that by cloning humans, we will gain the much needed medical advantage and understanding of illnesses and easily be able to avert, cure, or create person specific vaccines for the recipients of Human Cloning technology. Although these supporters have sound and valid arguments, they fail to see that Human Clones are just as their name implies, human beings. Even though they are the final product of a highly complicated medical science, it does not erase the fact that these people shall, in the future, be born into this world as innocents. They will experience life and live their lives until some doctor tells them they can no longer live because their body parts are now needed. In other words, Human cloning turns their creators, the doctors and clone nurturers into gods. Having the power to give and take a life at their own convenience and hide the murder of another human being behind the cloak of medical science and technological advancement. Man was not created in a manner that he can be allowed by natural forces to live forever. Our bodies were not designed to be like car parts that can be replaced once it is worn down. Transplant technology is one thing. Such a technology is governed by rules and often comes from donors who are no longer part of this world. Such an argument cannot be used in support of human cloning. It is one thing to take a perfectly good body part from a person whom you know no longer has any use for it and another to harvest a body part from an exact genetic replica of a person in order to save his life. Think about it. What good is it to save the life of one if it means that another must die in order

Promoting Team Effectiveness Essay Example | Topics and Well Written Essays - 1250 words

Promoting Team Effectiveness - Essay Example Individual conflicts tend to be about personality differences in terms of preference, likes and dislikes, background and so on. These differences are natural and can be a double edged sword. If not managed properly the individual differences lead to team conflicts. Team conflict is characterized by constant disagreements, mistrust among team members, and formation of cliques which act against each other and so on. A case of individual conflict is a situation at the workplace whereby two ladies in a team fail to get along because they share affections for a fellow male colleague. In such a case this problem is purely individual. An example of team conflict is whereby members disagree about the sharing of responsibilities and work in the team. In such a case the problems emanate from the issues that are team related Decision making in a team can be difficult because it may be hard to reach a compromise whereby everyone in the team feels satisfied and like a winner. Additionally, selfish interests among team members may inhibit smooth decision making. However, in contrast, a team leader may experience problem of indifference or disinterest among team members in the area of decision making so that the leader feels disserted when making decisions. Further, a decision affecting team affairs may need to be discussed among team members and welcome their input on the matter which in turn complicates decision making. More often than not these problems of decision making stem from unclear team goals and vision, confusion over who has the final say, unwillingness to take responsibility, selfish interests among other reasons. As a leader, it is important to ensure that these issues do not extend to the point of breaking team spirit which takes so long to build. For example the problem of team members purs ing individual interests first may be resolved by elevating the team's common goal and urging members to realize that the team is bigger than their individual goals. The problem of disinterest or indifferentness in the process of decision making can be conquered by delegating duties more to team members such that they feel more competent to contribute ideas. Perhaps the problem may be that members do not feel valued in the team in which case the atmosphere within the team should change to be accommodating. Question 4 Participation is a strong aspect that attributes to effective teams. Some of the benefits of participation include greater performance/output, efficiency and effectiveness, cohesiveness, growth, innovation and so on. Given the crucial benefits of participation team leaders can devise various methods in order to stimulate/enhance participation, for instance at the workplace a manager may use delegation as a way of promoting participation. Where delegation is made part of the work culture then individuals are forced to step up beyond their comfort zones and participate in team activities. A manager may also reward system to members who show active participation in team activities so that others are enticed to participate too. Importantly, a warm atmosphere and trust in the workplace needs to be nurtured so that team members feel free and uninhibited to participate in activities. Criticisms, gossip and self centeredness should be kept at bay. Communication is also key in fostering parti cipation in the workplace. A team leader should be able to communicate to
