Medical Ethics: Patient Wishes vs Doctor Actions :: Medical Ethics

A conflict between a doctor who wants to treat his patient a certain way, and a patient who wants to be treated by the doctor the way she wants. The doctor feels the that certain treatment that the patient wants is dangerous and warns the patient that he will pronounce the patient mentally unstable. This is exactly what happened in the case of Mrs. Jackson and Dr. Lowell. The conflict in this entire article is if weather the doctor can, or can not, accuse his patient mental instability to go about the treatment as he sees fit. Is this an invasion of the patient’s wants and desire for a certain way of treatment? or does the doctor have moral rights to do anything and everything even though it is against the patient’s wishes. What justifies as moral and immoral procedure for a doctor to treat his patient. When faced with this hard dilemma, the article suggests that is use Rule Utilitarianism and Kantian Deontology, to help me solve the problem of weather this justifiable or morally incorrect. Rule Utilitarianism basically reads that â€Å"a person ought to act in accordance with the the rule that, if generally followed, would produce the greatest balance of good over evil.†(Mappes & Degrazia, 13) According to this, if anyone faces a moral dilemma, they should always try to sort of do a Cost/Benefits analysis on the outcomes of their actions versus the good that they would cause. So even today when I was debating if or not I should personally write my research essay, or, pay somebody else to write my essay for me, it took me all of 30 second to decides that even though I might not like what i would be doing for the next three to four hours, part of me know that the happiness i would get from it was unparalleled to anything. However, now, if you look at the Kantian Deon tology, you will find a lot of things that are different. What this theory of morality says is the outcomes are not at all important, but your duty hold precedence over anything. Similar to Rule Utilitarianism, this theory of morality says that any act, as long as it complies with a rule, is morally justified. When we think about this problem in a rule utilitarian way, we have to abide by the rules which clearly state that the patient has the final say in what treatment is going to be used on them.

Circularity and Stability :: Philosophy Philosophical Papers

Circularity and Stability William Alston argues that there is no way to show that any of our basic sources of belief is reliable without falling into epistemic circularity, i.e. relying at some point on premises that are themselves derived from the very same source. His appeal to practical rationality is an attempt to evaluate our sources of belief without relying on beliefs that are based on the sources under scrutiny and thus without just presupposing their reliability. I argue that this attempt fails and that Ernest Sosa’s appeal to the coherence theory of justification fails, too, if it is understood as an attempt to find a similar external evaluation of our sources of belief that does not just assume their reliability. I concluded that there is no alternative to taking an internal view to our own reliability and embracing epistemic circularity. Why suppose that any of the bases on which we regularly and unquestionably form beliefs are reliable? Why suppose that sense perception, in particular, is a reliable source of information of the physical environment? These are questions that William Alston raises in his recent books Perceiving God (1991) and The Reliability of Sense Perception (1993). He argues that there is no way to show that any of our basic sources of belief is reliable without falling into epistemic circularity. There is no way to show that such a source is reliable without relying at some point or another on premises that are themselves derived from that source. So we cannot have any non-circular reasons for supposing that the sources on which we base our beliefs are reliable. Alston thinks, however, that there is a way of evaluating the reliability of our sources of belief that is independent of the beliefs based on those sources and that does not therefore fall into circularity. I will argue that Alston's attempt to find such an external support for our sources of beliefs fails. I will also consider Ernest Sosa's (1994, 1995) most recent attempt to deal with the problem and argue that if it is understood as a related attempt to find an external standpoint from which to evaluate our sources of belief, it fails, too. I will conclude that there is no alternative to a purely internal approach in which we evaluate our sources of beliefs in terms of the beliefs that derive from the very same sources and thus to embracing epistemic circularity.

The Dance

My twenty-year-old daughter Brandy called me the other night. While we were talking, she asked me if I remembered the day we watched a spider spin its web. I told her that I did, and she went on to tell me that the experience was one of her fondest childhood memories. She was a little surprised when I told her it was also one of my favorite parenting memories! Our family consisted of myself, my wife Sharon, Scott, my twelve-year-old stepson, eight-year-old Hugh, seven-year-old Brandy, five-year-old Justin, two cats and a Labrador mix named Mitch. Since our apartment had only a small yard, the kids and I would take Mitch on short daily walks during the week. On the weekends, whenever possible, we would take him on long walks through our small coastal community. During one of these weekend walks, we saw the spider. It was Sunday afternoon on a beautiful California spring day. The sun was shining while the birds added their sweet melodies. The air was filled with that special atmosphere of newness that is unique to springtime. My four children, Mitch and I were headed east, down Ninth Street. Ninth Street, in this part of town, is mostly small shops and offices, and most of these are closed on Sundays. Mitch, like all dogs, felt bound to investigate every tree or shrub along the path. As he was inspecting an oleander shrub in front of a small flower shop with an alcove, I noticed the spider scurrying about in the left corner of the alcove. Since most of the spiders I encounter usually just sit around waiting for lunch, I stepped over to investigate this little flurry of activity. It appeared the little fellow was building a new home. The spider had already built the main structure of its spiral web. The supporting rays of silk were attached to various points on the stucco wall and window casing, and the first few spirals, at the center of the rays, had been completed. I gathered the kids into the alcove and showed them the web. Mitch, having lost interest in the oleander, settled into the shade of the alcove for a nap. As we watched, the spider began a fascinating dance! Its eight legs moved swiftly in a repeating sequence, while its abdomen pivoted from one ray to the next spinning silk, all the while moving in an ever expanding spiral. We continued to watch the little spider until it reached what it, and Mother Nature, determined to be the outer ring of its new home. Every one of us, except Mitch (who was still napping), were enchanted and impressed with the performance. The spider, however, appeared oblivious to our adulation. As we continued our walk, we talked about the spider over and over. When we got back home, all four children kept interrupting each other in their eagerness to describe to their mother what they had seen. Hugh did an enthusiastic imitation of the spider's dance, wiggling his fanny to and fro while gesticulating wildly with his arms and legs. His efforts had us all laughing until we had tears in our eyes. I have always been charmed by the natural world: the acrobatics of squirrels, the cooing of pigeons, the soaring flight of hawks and falcons. Just the sight of a dragonfly sitting still on the end of my fishing pole grips my soul and fascinates my eyes. I had always hoped that I would pass my love of nature on to my children, so that they too would know the particular wonder that only nature can inspire. At the time as I watched and listened to my children's excitement over the simple dance of a small spider, I felt my hope might be becoming a reality. Knowing that the memory is still cherished by Brandy thirteen years later I feel sure she, at least, got the lesson right.

Ah, Woe Is Me

In the beginning of this short story we are introduced to Sarah, an aging black servant living in South Africa. She works hard for an upper-class white family and spends all of her money on education for her three children who are sent to a boarding school. They come home once a year at Christmas, and the first time the narrator meets the children, she is surprised at their well-mannered behaviour. She finds, however, that Sarah is a bit harsh towards them, and she comments on this. Sarah tells her that it is better to learn the lesson now and grow to accept ones fate later. In the course of the following year, Sarah must give up her job because of her legs, and one day her daughter comes to the house. Slowly she tells her story to the narrator. How the younger brother is working now, and how she is taking care of Sarah. The narrator offers her some clothes and some money and invites her inside for a cup of tea. When she is about to leave, she starts crying and can only mutter that her mother is very ill. Unsure of what to do, the narrator hands her a handkerchief. The setting in this story is South Africa in the 1950s. Apartheid and segregation are words that describe the conditions under which the blacks (the native Africans) live perfectly. The blacks nearly have no rights and must accept being oppressed by the whites. Sarah is only one of many poor blacks who only just manages to earn a living by working as a servant for a rich white family (the narrator). Slavery does not exist anymore, but it can be difficult to distuingish the life of a slave from that of a native African in the 50s except from the fact that they do after all get paid for their work. Sarah is very concerned about her children getting a good education. She probably wants them to have a better life than she has had so far, and while that is a very noble thought, the facts speak against it. Her children do not at this time have a very good (if any) chance of getting a good solid education because it is very expensive, and their mother does not make that much money. Even if she did make enough money, her legs are bad, and at the end of the story, she has to give up her job (and thus take her children out of the boarding school) because she cannot afford to pay for the school. This is what could look like the final blow to her childrens future success in life. No education means no chances of getting a better life in South Africa (and just about everywhere else, too). But what if she did have enough money to give her children a proper education – would that guarantee the children a good future life I gravely doubt it. As I said before, the blacks live almost like slaves, and as such, they do not have the opportunity to climb the social ladder. All in all, Sarahs hopes and dreams for her children are all very noble, but, unfortunately, at that time and place, very unrealistic. The narrator does not treat Sarah any better than most other white people in South Africa at this time. While she allows Sarahs children to stay in her house during Christmas, I think the only reason she does it is because she tries to escape her own bad conscience. It is Christmas after all. Throughout the rest of the year, she does not even think about helping Sarahs children financially so they can stay in school. Even though she presumably has more money than Sarah will ever see, the thought of helping her servant out does not strike her at any point in the story. Her servant is her servant, and servants children are not someone she thinks about. This point is also very clear to see when one reads the description of the narrators thoughts about Sarahs children. She is surprised at how well they behave, how good their manners are; as if she was expecting a horde of wild animals instead of normal human beings. She is undoubtedly not the only one to think this way about the blacks, they were considered animals by many white people at that time. However, the narrator seems to excuse her treatment and behaviour towards Sarah and her family with ignorance (see lines 99-103). I find it hard to believe that this ignorance really existed, but it is possible that it did, because the whites and the blacks were so distinctly segregated by the apartheid system. Yet I find it hard to believe that the narrator was completely unaware of Sarahs almost inhuman standard of living. Surely, even though apartheid almost divided the whites and the blacks into two separate worlds, she must have known something about the conditions under which Sarah and her children lived, and that it was getting worse as the days went by (because of the mothers bad legs). When Janet, one of Sarahs two daughters, comes to visit the narrator in the end of the story, the narrator once again displays her ignorance about the blacks, but this time she openly admits it. Janet is, of course, in an unpleasant situation when she stands in the back yard of her mothers former employer. Everyone has some pride in themselves, and standing in the back yard, asking for alms is, of course, very degrading to a proud person, no matter who that person is. Janet has probably tried being in a similar situation before, but now that her mother is unable to provide for the disintegrating family (her father has lost his job and her sister has married and moved away), the life and death of her family depends solely on her and her brother who are the only ones working. Janet is of course very depressed and sad, but she cannot give up now. Her last hope is that the narrator will help her out, and, fortunately, she does. The handkerchief is actually the first thing the narrator has ever done to help Sarahs children. It is not until that point in the story Janet realizes just how bad things are with Sarah and her family. Of course, one could again be tempted to think that it was only her bad conscience that made her give Janet the clothes, but there is no way to be sure. I am, however, inclined to believe that the narrator has finally realized how immense the difference between the â€Å"black world† and the â€Å"white world† really is. However, the things she gives Janet (some money and the handkerchief) will not last long, and what will Janet do then Come back for more, of course. I am not saying that the narrator is doing something bad, but I do not think she realizes that Janet will probably come back again. It is like giving a stray cat some food; it will always come back for more. The question is if the narrator would give Janet more money if she came back, and if it would be any help at all. The first question is easy: Yes, she would give her more money if she came back – her conscience forbids her to do otherwise. The second question is a bit more difficult to answer. Of course the money is an instant help to Janet and her family, but only a very insufficient one. The few dollars (or whatever currency they use in South Africa) she gives Janet will only provide the family with a meal or two, and after that they will be back to where they started, and would have to beg for more money. Now, I am not saying charity does not help, but I do not think it helps as much as many people would like to think it does. In many cases, it only puts off the sufferings. The apartheid system has officially been abolished in South Africa today, but I think old habits die hard, so to speak. I am sure there are still blacks like Sarah and her family who have to subordinate to the richer white population even though – officially – apartheid does not exist there anymore. Societies do not change overnight, especially not when one group has to give up its right and privileges and share them with others (whom they dislike). Sarahs story is undoubtedly not the worst example one could find, but no one knows what happened after the scene in the narrators back yard.

How Vampirism Is Depicted in Dracula by Stoker and I Am a Legend by Richard Matheson Essay

Vampires are creatures that are believed to feed on flesh blood of living things and especially human beings. From the novels, vampires evolved from dead human beings and came back to life with more powers than them making them super humans. To understand vampires’ evolution, different myths were developed across the world. Ancient Persia recorded their first history as most Greek and Roman myths tried to expound further on their evolution. In the history recordings, vampires were depicted as huge creatures who struggled with human beings to feed on their blood. They further differed with human being in that; they could not age or contract diseases. Their immunity to diseases prevented them infections from human beings when they fed on their flesh and blood. Although many history recordings argued on traditional history, there existed some modern vampires that first appeared in Europe. In contrast, myths also recorded a different category of vampires whose origin was not from dead human beings but with temporal incarnation between humans and vampire. This category included blood thirsty goddesses, who were classified as Stinges, Lamiae and Empusae that fed on blood occasionally. Vampirism                  Vampirism can be defined as the act of feeding on flesh and blood of living things other than vampires. When feeding the blood of human beings, vampires bite the victims’ neck sucking out large volumes of blood. Through neck biting, they are able to injure the carotid artery, which is the major artery that transports blood to the brain hence paralyzing the victim and sucking the whole blood. Vampirism is regarded as a belief of one gaining supernatural powers and feeding on human beings blood in the folklore and popular culture. Stoker tried to expound on vampires by using them as characters in his book Dracula. In this book, Dracula, who is a vampire, is the main character. The author explained how the vampire had lived for many years, which was atypical for a normal human being. Similarly, Richard Matheson book was dominated by vampires who were created by infusion of viruses. Although people could be infected with vampirism virus, Matheson brings out the nature of immunity where one of his characters Robert Neville never contracted vampirism despite being infected. He was immune to the virus though he had unique human characteristics such as blond hair and blue eyes. Matheson described Neville as an educated medical researcher who concentrated on the research on vampirism only to find out that his blood was infected though immune to the virus. Vampires in the Text                  Stoker used different vampire characters to construct his book story. Dracula, the most dominant vampire in the story was described as the king by other characters such as Van Heslin. He was very powerful and he could control nature as well as living creatures such as wild animals. In addition, Dracula has the ability to incarnate to a bat, werewolf and change his victims into vampires through infections. His ability to hypnotize his victims gave him control over them and avoided being hurt by others. Despite his powerful nature, Dracula had a number of weaknesses as described herein. His powers were limited by reflecting him on reflective objects such as mirrors. This was evidenced when Jonathan tried to reflect his image on a shaving mirror. He lost his powers and became weak to the extent of being controlled by another person. Stoker emphasized in his book, despite the weakness, it was hard to fully destroy Dracula. More weaknesses emerged as holy symb ols and garlic repelled him and his sleep was on the fate of ancestors and the native land. He did not have ability to cross river, which water was following unless supported my men or the luck of the water. This showed how he could be controlled or destroyed in cases he became so dangerous. Matheson classified vampires in two categories, which included the dead and the living ones. Similarly, as Stokers described, he depicts vampires as being repulsive to garlic and holy symbols. For example, Christian vampires feared the cross as it was a sign of holiness. Matheson explained how Neville destroyed vampires by exposing them to sunlight, inflicting large wounds and staking them with wooden spike. Comparison between the Two Works                  Both authors acknowledged garlic and religious symbols as repellant to vampires. For example, Ruth recoiled violently when Neville handed garlic over her in Matheson book and Dracula when dining with Jonathan avoided feeding on garlic. In both texts, vampires relied on flesh and blood as their main food that strengthened them. For example, Dracula in the first paragraph almost attacks Jonathan when he cuts himself. Vampires are depicted feeding on blood by Matheson and he uses the phrase blood thirst to emphasize on their need of blood. Superstition is also another theme that was described in both books. Stocker explained how Van Helsing and Seward followed the garlic superstitions from the old country where they were believed to ward off spirits by protecting themselves by them. Religious symbols such as bread and cross represented Christ and his Body (stoker 123). Despite Neville’s ability to destroy vampires, he still used garlic to protect himself strengthening the theme of superstitions in the text. Both authors described vampirism as contagious from vampires to normal people. People who survived attack by vampires were infected through bites and insects. For example, Neville was infected by vampirism and his immune ability prevented him from transformation to vampire. In both books, vampires appeared to be enemies of the normal people. In I Am a Legend, the human race was insignificant as most of them were destroyed and killed by vampires. Moreover, Neville struggles with vampires and kill most of his encounters at nights. Stoker explained how Helsing had lived wanting to conquer and destroy the Dracula and how people continuously warned him and Jonathan against close association with the monster Dracula. The conspiracy, fights, and killings between vampires and the normal human beings is an evidence of enmity between the two races. In both books, vampires’ body circulations were totally different from those of normal human beings. For example, when Neville killed a woman vampire for research in Matheson’s book, he found that her body contained rows of salt and pepper mixed the same ratios (Matheson 60). Similarly, Stoker explained how vampirism victims could not be transfused with blood from normal people and their fate was solely on supernatural powers to heal them. On the other hand both books described contrasting characters on vampire and discussed below. Vampires described by Stoker were difficult to destroy and kill and were only destabilized by refection. On contrary, vampires described by Matheson were easily killed by exposure of sunlight and infliction of wound that were staked. According to stoker, vampires were as a result of the work with supernatural evil spirits that were connected to dead. In contrast, Matheson wrote that vampires were created by infusion of microorganisms such as bacteria and viruses. Matheson described the evolution and development of vampires as progressive. That is, they grew from young to strong creatures that mutated at some points and they could spend some times in the sun. Stoker described vampires’ development as retrogressive, growing from old weak creature to young strong creature through feeding of blood. Stoker work was based on religious beliefs and his main aim was to strengthen and restore r eligious faith in the society. He did this by creating a scenario where vampires who were believed to be evil became afraid of holy symbols and supreme powers. It was learnt from the text that, vampires feared holy waters and for that reasons people could protect themselves from them. Dracula represented devil and this was expressed more by name of his home in London, Piccadilly. The word appears to be close to the word peccadillo â€Å"a slight offence† or sin (Merriam-Webster 530). Matheson work in contrary was not based on spirituality. His entire book denounces the interrelationship between God and humanity as evidenced by Neville when he did not depend on invisible beings when trying to destroy and kill vampires. He was more dependent on his vampire research, which was facilitated by his medical research career. According to science, the reliance on invisible being appears absurd and science does not validate it. In both books, the concepts of vampirism indicate the wickedness of humankind as it is concerned with termination of life and shedding of blood. This is against the societies norms and values and the books were written to address the evils. Matheson brought out vampires in his book as unique and modified enabling them to be more alluring to the intended target audience. This was contradictory to those in Stoker’s book where they were depicted as monsters of devil’s associates thus attracting believers as the main audience. This would help the believers appreciate the mighty power of God that made devil afraid as evidence by Dracula avoiding religious symbols. On the other hand, the target audiences for Matheson work are mainly non-believers as most of the characters such as Neville were never afraid of super beings or supernatural powers. He uses the assumption that the doctoring of individuals affects what they fear and what they do not (Matheson123). Neville discovered the reflective character of vampires in Matheson book, which was opposed to those described by Stoker (Matheson 16). In the book, I Am a Legend, Neville searches a scientific cure for vampirism from his blood due to its immunity unique character on vampirism. Although his initial trials to heal vampires had aborted, he continued to search for a solution ceaselessly. Fortunately, he found the cure, which could depress the vampires thirst for blood thus reducing their threats on human beings. This was the not the case in the text of Dracula. Vampires in both books appear as creatures, societies uphold their beliefs and norms without permitting vampires to despise them. Despite the vampires being hostile to people, they struggled to push the out of the society and denounced their evil deed across the society through eliminating them. Society struggled to push Dracula out of the society but his unnatural power defended him and the society attempts were in vain. Their fear of evil spirits prevented them from his attack and instead hoped for a savior who will come for their help. The society saw Helsing as their savior and their belief in God. He was a well-learned doctor who had an open mind and thus was probable the person to save them (Stoker 109). The two books targeted the evils in the society by addressing them and trying to bring people closer to a supreme being, God. Perhaps, the society was full of evils at the time of writing and so it was necessary to address the issues through text. It can also be assumed that, people used texts or books to learn most of the things in the societies and thus there was need to use the medium to communicate exclusively to the people. From the fact that Christianity (Church) was evident in the texts, the authors revolved their writings around it acknowledging God as the protector of human race from all sources of evils such as vampires in the book society. The individuals were protected by religious artifacts that was evidenced by possession of religious symbols by Helsing had religious items such as holy waters, which helped to protect the society from evils. Matheson described Neville as having tattoo of a cross which served as vampire repellant thus to some extent having religious belie fs. Not much was explained in the about Christianity and the church. Some of the people in the society were enlightened and had both scientific knowledge and religious beliefs to deal with the evils associated with the vampires. The authors of the books were skilled and considered perception of the people when writing so that they could be able reach and impact on the people’s ways of life. For a typical author, he or she must be able to understand his or her audience in order to deliver a relevant message and in an appropriate way without provoking them. Matheson and Stoker used this aspect and combined it with the knowledge of vampires and their attitude in the society. The use of vampires in both books was fundamental as they depicted the evils in the modern that are caused by various abnormalities as Matheson explained one of the cause to be the second world war. Therefore, by use of reality and fiction, the authors were able to prove their worthiness in literature and society. Conclusion                  Both books used vampires to deliver their messages to the respective societies. They depicted societies that were full of hostilities and blood spilling between vampires and normal human race. Although the vampires in both books had common characteristics such as feeding on human blood, they exhibited slight differences on their evolution and development. The books attracted varied audiences with Dracula attracting audience of vampires who knew Dracula as the best vampire in history. The books addressed the political views of the time with Stocker in being more concerned on Europe where the church was prominent in the political scene with believers as rulers such kings and queens. In the Matheson book, the issue of the world war was described as politically influenced and depicted how mankind would be swept off on earth by stronger weapons than nuclear if wars were to recur.

Explanation: increase of reaction why? Increases in the temperature of a system results from increases in the kinetic energy of the system. This has several effects on the rates of reactions, 1-the increase in temperature will increase the activation energy of a molecules there for it has more potential to react and change status Also the temperature will make the molecules move faster and as a result more collision will be possible per/minute . Enzyme’s activity stops why? Altogether and that is because of the heat changes the shape of the enzyme molecules preventing them from working ,this is called (denaturation ) in fact enzymes will denature and any temperature that is why they cannot be used over and over again ,however the higher the temperature the less time it takes for the denaturation to occurs . 5.

The law of the defences to actions for tortiously inflicted death and Essay

The law of the defences to actions for tortiously inflicted death and serious injury lacks any conceptual coherence. It would be - Essay Example However, legislation in respect of this has reduced the scope of such defences. A general analysis of the defences would be made and their effect in respect of what is required would be considered. Prior to the Law Reform (Contributory Negligence) Act 1945, contributory negligence of the Plaintiff would constitute to be a complete defence in respect of claims of negligence. The Act allows courts to allocate responsibility in respect of damage and attribute it accordingly between the defendant and claimant and then to apportion the claimant’s damages, thus making it a partial defence. Contributory Negligence is a defence which makes available a partial defence in respect of a claim in tort. The aspect of this defence is primarily concerned with the fact that the claimant was careless and this was a material cause in respect of the loss that he suffered. The defence therefore operates as a partial exclusion as to liability. The Act has simplified the law in respect of the defenc e. ... respect of the modern defence, that is, causation; concept of claimant’s fault; what is the position in respect of special elements in relation to certain claimants and how what they be accounted for; how the loss would be apportioned; and how the defence is to apply in respect of torts apart from negligence. The problem in respect of causation is the fact that the apportionment has to be made in accordance with the causation and takes into account the plaintiff’s carelessness as can be seen in McLew v. Holland and Hannen and Cubitts (Scotland) Ltd.1 whereby it was held that the plaintiff’s act was novus actus interveniens and therefore the chain of causation was broken. The last opportunity rule, even though, been discredited, was used in this case. However, the courts in Reeves v. Commissioner of Police for the Metropolis2 found that even though the deceased committed suicide, the causal link had not been broken. As far as the claimant’s fault is concern ed, there is no requirement of a duty of care being owed and the Act merely requires an act or omission and therefore torts, other than of negligence are also covered. After an evaluation of the contributory negligence that court would decrease the damages of the claimant ‘to such an extent as [it] thinks just and equitable having regard to [his] share in the responsibility for the damage’ (Law Reform (Contributory Negligence) Act 1945, s.1. The evaluation in respect of the deduction is therefore left at the discretion of the judges and an evaluation in this respect was made by Lord Denning in Davies v. Swan Motor Co.34 Damage in respect of Contributory Negligence include but is not limited to loss of life and personal injury. Thus it can apply to cases of pure economic loss as well. There have been
