...Persuasive Speech: Euthanasia. The word “Euthanasia” comes from the Greek words meaning “good death.” In practice, it has come to mean the selective killing of those who are old, young and sick. Worldwide, support for the practice appears to be increasing. However, in today’s society, there are deeper and more layers of meaning to euthanasia than before. There are three basic types of euthanasia: Voluntary, non- voluntary and involuntary. Voluntary euthanasia concerns itself with the express wish of a mentally competent person to die through the assistance of others. Voluntary euthanasia can further be divided into two categories: passive voluntary, which is the specifically requested withholding of unwanted medical treatment, and active voluntary which is the deliberate action of killing the patient at that patients informed request. Should dying human beings be made to suffer horribly during their last days in this world before looking forward to a painful and undignified death when they wish it to be otherwise? The answer is no. As such voluntary euthanasia should be legalized for the terminally ill patients. For many people, euthanasia is a preferable option to dependence and unbearable suffering. A study was conducted on patents’ assessment of states worse than death by Robert Pearlman, a physican specializing in geriatric care at the Seattle Veterans Heath Center. In depth interviews were held with 56 suffering from cancer, AIDS, or who had spent time in a coma from...

...for the U.S. government’s treatment of Indians made him move to Montana to carve out his own existence. His wife remains back East and Ludlow raises his three boys, Alfred, Tristan, and Samuel. The action plays out against the Indian Wars and World War I. In the film of Harrison’s novella of the same title, the development of the three boys is comparable to their experience in the novella. In both works, their development revolves around the themes of death and survival, with Tristan discovering one must forge his own meaning of existence in order to survive. Body The three sons of Colonel Ludlow are adept at hunting and have a rapport with Native Americans in both the book and film. Samuel enlists in the War after marrying a woman, though he is a virgin. Alfred and Tristan also enlist. Samuel is killed and Tristan goes mad in his revenge of his brother’s death, scalping numerous Germans and cutting out his brother’s heart to send back home. In his interactions with his family and others and even in death, however, Tristan remains “apart, somehow solitary” (Harrison 276). Like his father, Tristan exhibits distaste over the U.S. Cavalry’s treatment of Indians. In both the film and novella, Tristan is influenced by his father’s treatise on the “Indian question,” and his father’s attitudes toward society, “Screw’m! Screw’m all! Screw the gov’m’nt” (Zwick 1994)! Tristan marries Samuel’s widow, but while lost at sea and presumed dead she marries another...

...Emily Dickinson The poem “Because I could not stop for death” by Emily Dickinson is based on several cognitive metaphors, for instance: life is a journey or life is a cycle. They are expressed explicitly; life ends with a journey through all the destinations enumerated in the poem; it has a start and the final point. Also life is a path, because they follow the path and at its sides they observe different things and people. The metaphor life is a day is expressed by the lines “we passed the fields of gazing grain, We passed the setting Sun”, where, obviously, the first image means young ages and the second one is about the old ones. This metaphor is widely used in folk texts and in both Russian and Ukrainian languages there are correspondences e. g. на закате своих дней. The pattern purposes are destinations suits this poem because the person dies but this process is described as moving to the other place. The image of the HOUSE is important for the poem. It symbolizes a coffin, or the final destination, or the end of the journey. This complex image renders the beliefs that the dead live in their world under the ground, because only alive people need a place to live. It is interesting that in this poem Death is addressed like “he”. It reveals the difference between American and Ukrainian concepts: for us death is a woman and for them it is a man (or for this particular literary text). One of the possible interpretations is that men tend to destroy everything. Here it is...

After being an active retiree she listened to scientists of the University of Kentucky and agreed when the head scientist said that donating your brain for research on Alzheimer’s is very beneficial. She was all for it and joined 678 school sisters in signing up. She almost at the maximum age for the study where the range of ages were from 75 to 102. After being put through a series of tests her last test in the Nun study was Mini Mental State Examination where she scored high which was remarkable due to her age and less formal education than other participants. After death of most of the subjects neuropathical evaluations were completed on 118 sisters. Scientists had many findings with Sister Mary and other sisters such as nuerofibrillary tangles in the neocortex and brain weight. They found that the different scores on the tests given related to the brain function to the sisters after they had past away. One main purpose it seems it his study is to find out what happens in someone’s life that triggers this disease and where it effects. The scientists seem like they want and need more subjects who are whiling to let research be done on them after they move on in life. This seems to be the best way for scientists and other researchers to get a good idea of what can be done and are the leading...

...Scott Morris Miss Douglas Comm - 1113 1 Nov 2012 Euthanasia: Who Owns the Right to Die? Throughout there have been many instances in which the pain and suffering of individuals overcomes their own desire to live. It is a tragedy to say the least, and it is something that nobody wants to ever have to deal with under any circumstances. In very rare cases in the more recent past, some have turned to others to help ease their ongoing pain in one of the quickest, but extremely permanent, ways. Euthanasia, or sometimes also referred to as assisted suicide, is the practice of intentionally ending a life in order to relieve pain and suffering. The choice itself is not for everyone, and never should be. It should be reserved to the very few who’s daily physical pain is keeping them in much more agony, and that they themselves are in a conscious state to know what they are experiencing and that they would like it more otherwise. On one side, you can say that in the end it should be the individuals’ choice themselves, and other people should not stand in the way simply because they do not know what they are experiencing in the case of a terminal illness. It may be hard for those who care about the individual, but they should be able to respect the wishes of those who are in pain to have some type of closure. But on the other hand, these same people might not be in the right mental or physical states to make an educated decision that has not been influenced by others own opinions...

...Case Study 2: Suicide or Well-Reasoned End-of –Life Decision? In the case of Jason, the 38 year old gay man with AIDS who is considering a rational suicide, there are several ethical and legal issues that the counselor has to consider in order to effectively continue to treat the client. Jason has disclosed to his counselor that he was considering to stop taking his medications which will ultimately end his life. Upon receiving this information from the client , the counselor has to now consider if he or she has any personal, moral issues, or spiritual belief system about the end -of -life decisions that might conflict with what the client has decided. The counselor should consult with a supervisor or some one who has some experience in the area of end-of – life. If there are any conflicts, the counselor can chose to not work with the client and provide him with an adequate referral to make sure he get the help he needs. (Standard A.9.b). A counselor should never impose his or her beliefs, morals or spirituality on their client. This will impede the client’s ability to achieve autonomy and self –determination. According to the ACA Code of Ethics, the counselor has to protect the client’s right to self-determination, ensure that the client has a quality end of life that satisfies their emotional, physical , social and spiritual needs and to ensure that the client is competent to make the competent decisions via...

...Hamlet To be, or not to be: that is the question: Whether ’tis nobler in the mind to suffer The slings and arrows of outrageous fortune Or to take arms against a sea of troubles, And by opposing end them. To die, to sleep— No more—and by a sleep to say we end The heartache, and the thousand natural shocks That flesh is heir to! ’tis a consummation Devoutly to be wished. To die, to sleep;— To sleep—perchance to dream:—ay, there’s the rub, For in that sleep of death what dreams may come, When we have shuffled off this mortal coil, Must give us pause: there’s the respect That makes calamity of so long life; For who would bear the whips and scorns of time, Th’ oppressor’s wrong, the proud man’s contumely, The pangs of despised love, the law’s delay, The insolence of office, and the spurns That patient merit of th’ unworthy takes, When he himself might his quietus make With a bare bodkin? who would these fardels bear, To grunt and sweat under a weary life, But that the dread of something after death,— The undiscovered country, from whose bourn No traveller returns, puzzles the will, And makes us rather bear those ills we have Than fly to others that we know not of? Thus conscience does make cowards of us all, And thus the native hue of resolution Is sicklied o’er with the pale cast of thought; And enterprises of great pitch and moment, With this regard, their currents turn awry, And lose the name of action. —Soft you now, The fair Ophelia! —Nymph, in...

...01) “A Man Is Never Too Old to Learn” The world of knowledge is so interesting and enchanting. It is full of different kind of information, a lot of facts and details. Opening its gates you pass into the space of unknown things, you discover something new. As a rule, we study when we are young in order to make a career, to have success and to assure for ourselves a decent level of life. I think it is correct, because at the age when we graduate from school we have to determine ourselves in what direction we’ll continue our studies. It is important to us, because in this way we determine the course of our future life. I believe we should study as much as we can, because knowledge is a real wealth and a good friend that will never betray us. Learning each day we contribute to the development of our personality and in this way we have the possibility to discover new unknown talents. We can discover them at different ages. In life there are different cases to prove it. For example a person at the age of 50 may discover that he or she is interested in painting. After these amazing discoveries as they seem to old aged people, some of them even enter the university and develop their skills in the sphere they are interested in. I admire such people, because they have no fear that other people would criticize them for their actions. But to my regret, many old aged people, even if they are interested in something, don’t begin to study, saying that they...

...THE STORY OF THE AGED MOTHER A Japanese Folktale Long, long ago there lived at the foot of the mountain a poor farmer and his aged, widowed mother. Theyowned a bit of land which supplied them with food, and their humble were peaceful and happy.Shinano was governed by a despotic leader who though a warrior, had a great and cowardly shrinking fromanything suggestive of failing health and strength. This caused him to send out a cruel proclamation. The entireprovince was given strict orders to immediately put to death all aged people. Those were barbarous days, andthe custom of abandoning old people to die was not common. The poor farmer loved his aged mother withtender reverence, and the order filled his heart with sorrow. But no one ever thought a second time aboutobeying the mandate of the governor, so with many deep hopeless sighs, the youth prepared for what at thattime was considered the kindest mode of death.Just at sundown, when his day’s work was ended, he took a quantity of unwhitened rice which is principal foodfor poor, cooked and dried it, and tying it in a square cloth, swung and bundle around his neck along with a gourd filled with cool, sweet water. Then he lifted his helpless old mother to his back and stated on his painful journey up the mountain. The road was long and steep; the narrowed road was crossed and recrossed bymany paths made by the hunters and woodcutters. In some place, they mingled in a confused puzzled, but hegave no heed. One path or another...

...Goatee 1 Mary Goatee Professor Maroney English 101 8 June 2011 Euthanasia And Assisted Suicide Is Not Murder! My personal opinion is that euthanasia or assisted suicide is not murder when a person is already suffering and dying. Euthanasia is translated from Greek as “good death” or “easy death.” Euthanasia occurs when one person ends the life of another person for the purpose of ending the killed person's pain or suffering. Assisted suicide is closely related to euthanasia. An assisted suicide occurs when one person gives another person the instructions and means to commit the suicide themselves. A few proposals to legalize euthanasia were made in the United States and Germany during the latter portion of the nineteenth century. Now, Oregon, Washington, Montana, Netherlands, Belgium, and Luxembourg are the only jurisdictions in the world where laws specifically permit euthanasia or assisted suicide. The strongest argument made on behalf of legalizing euthanasia or assisted suicide is that it, like abortion, is a “choice issue.” It is a persons ultimate civil right. The possibility of a predictable escape from suffering if it becomes overwhelming is important to many patients. To deprive a mentally competent, terminally ill person who wants to end their suffering in a peaceful way is disrespecting their civil rights. Over 90% of people with terminal illness will endure their situation, but between 5 and 10% find it intolerable...

...Hiduism recognizes the necessity and significance of material needs and the enjoyment of them it does not acknowledge the fact that it fulfills ones existence. Wealth and pleasure are the first two teachings in Hinduism and they must be pursued with the dharma; the goal of Dharma is that they keep the welfare and of all others in mind as they attain their own personal goals. The highest goal or teaching in Hinduism is moksha which means liberation. Liberation is usually taught to a Hindu by a teacher, guru. In this religious belief the cause of human suffering is ignorance. Ignorance comes from desires and actions; such actions and desires create a multitude of consequences either later in life or in another life. This is where karma comes in to play, they believe if you do something wrong in this life you will be punished wither later in this life or in another life. They believe that one will have multiple births in order to achieve true liberation. Also, in order to attain liberation one must fully understand that the self is eternal and uncreated. (Rambachan, 2000). Hindus experience a vast amount of criticism, mostly because they worship what one can say as false gods. They worship values where other religions worship actual figures or persons. Their beliefs are not based on what a book says they are based on virtues, being able to attain true freedom from worldly desires and actions. Hindus have provided other groups with the sense of attaining true liberation...

Both see death as a stage in life and have been able to accept death as an eventuality and not something to be...
