Arthur Miller Essay Example for Free

Arthur Miller Essay Between 1949 and 1953, Arthur Miller wrote two of his most famous plays. Both plays dealt with major problems in society. The main characters of the plays were similar. Also, the supporting characters of both plays were alike. Arthur Millers plays Death of a Salesman and The Crucible are similar in many ways. The main purpose of both Death of a Salesman and The Crucible was to show major problems in American society. In Death of a Salesman, Arthur Miller was trying to show the impossibilities of the American Dream. In The Crucible, he was trying to show how society is intolerant toward others and is prone to hysteria. Both plays dealt with society defeating the average, hard-working man. Each play showed a society that was full of deceit and liars. In both of these plays, society was depicted as an evil thing that would overpower the average person and create an unjust world. The main characters of Death of a Salesman and The Crucible, Willy Loman and John Proctor, were alike in many ways. Both of these men had extramarital affairs, and in both cases, the affairs ended up destroying their lives. Both of these men were hard-working, average men who were just trying to make a good life for themselves and their families. Names were important to both men, and they both took pride in their names. In both cases, many decisions the two made were because of their family members. One large similarity between Willy and John was the fact that they both eventually died, and the death was partly their choice. Both men could have avoided death, but instead, they chose to die because they believed it was the correct thing to do. In these two plays, there were also many similarities between the supporting characters. In both plays, children had much more power than they normally do. In Death of a Salesman, Willys son controlled much of his life. In The Crucible, the girls, led primarily by Abigail Williams, caused many people to be hanged, and even more to be imprisoned. Also, both John and Willy had wives that were very loyal to them throughout their lives and supported them until the end. Both plays showed a figure of power, seen as Howard in one play and Judge Danforth in the other. In both plays, the main character had a friend who stood up for them at the end. Willy had Charley, who had been his best friend for a long time, and John had Reverend Hale, who tried to prevent Johns death. There are many similarities between characters in the two plays. Death of a Salesman and The Crucible are alike in many ways. Arthur Miller created similar characters in both plays. He used both to show the many things wrong in America. These two plays are both powerful pieces of literature that should be read and appreciated by all people.Sources: Death of a Salesman and The Crucible by Arthur Miller

Short Story on the Afterlife

Short Story on the Afterlife A Dream I Had About the Afterlife Last night I dreamed that I had died. It wasnt the normal kind of dream. It wasnt the kind of dream that you wake up enthralled, afraid, or tearful from. It was something deeper than that. When I died, there was no white light to walk toward, no staircase in the clouds, no golden gate atop them, no heavenly chorus scoring each and every one of my footsteps, as if each one of them pounded on the drums of destiny, no heart, no passion, no feeling that every breath I took in my mortal life led to this moment, and that now my dreams were coming true, and I was ascending towards everlasting glory. There was none of that. But equally there was no fear. There was no anxiety, or panic, or hopelessness. The four emotions I had forever associated with death. The emotions that had left my mind crippled, contemplating other alternatives to constantly living with the big day forever looming over me. Emotions that had rendered me useless, unable to function, wondering what we are doing on this planet, and why something as spectacular as life on earth, with its inconceivable beauty and ability to emote human euphoria, could have such a terrifying and mind numbing opposite as death, and how we could know so little about it other than at its existential core, it is nothing but the absence of life in a previously living body. No. Instead of fear or euphoria, there was realism. Quite frankly, there was no commotion. I had died in a hospital, in a small room, my loved ones surrounding me as I lay in a bed drifting off courtesy of an incurable disease, as so many have done before me, and so many will do after. As I faded I felt my woes fade also. I dont think we realise it when our lives are so busy, but we always have our woes or problems on our mind, we just dont notice them as much. I thought about my family and friends. They held hands and sobbed around my bedside, knowing they were witnessing the last moments of my human life. I guessed that I should have been worrying about them, how they would cope without me, but three familiar words kept circulating in my head. Life goes on. Life would go on for them. They would be sad, but they would find closure, and then eventually it would be their time to go too. None of these things worried me. I had always pondered the afterlife, and by this point I had accep ted that I would either see them again, or that I wouldnt need to. I understood that love transcends life. And then it happened; though it didnt happen instantly. Throughout life I had always imagined that the moment of death would be similar to an abrupt power-outage, where in a split second, darkness would engulf everything. But it wasnt. It was a gradual process and I wasnt quite sure when life had ended, and whatever came next had begun. Those around my bed began to leave the room. They left in an orderly fashion, as if it had previously been decided how they would do so. Each of them did so matter-of-factly, and that was the first sign that I may have passed over, as Im sure in normal circumstances they would be crying and mourning uncontrollably. Instead, each of them just left. Some of them held my hand before leaving, and others kissed my forehead. And then, just like that, I was alone, albeit for just a few seconds. It was in this moment that I realised that I was witnessing my death out of body. I was standing in the corner watching this happen, not lying in the bed. And then I realised that I now had a purpose. I sat at a table in the middle of the room. It was small and there were only two chairs. The version of myself that I had just been watching got out of bed and sat at the table also. I was sitting across the table from myself. Somehow looking into my own eyes and staring back at them at the same time. Only when you look into your own eyes can you comprehend your existence. And then we talked for what felt like an hour, and yet it could have lasted for a thousand years because any comprehension that I had of time in my human life had faded, and I began to think that maybe time didnt exist anymore. We talked about the life I had lived on earth, about the relationships I had formed and the feelings I had had, what I had achieved in life, and what mark I had left on the earth. And then I as ked myself what was going to happen next, and of course didnt know the answer. Just as quickly as I had realised what my role was in my own passing over ceremony, I became clueless even faster. And there I was. At a table with another person, and yet somehow completely alone simultaneously; with the most pondered question of all time, and not a single answer. I closed my eyes and breathed in. I took two more, long, similar breaths, and I held the last one. I opened my eyes. And then I saw everything. Every sunrise and sunset from every possible corner of the earth. Every flower that had ever bloomed, every tree that had ever grown, every mountain that had ever been conquered. Every creature on land, in the sky and in the oceans. Every man who had ever made his dreams come true and every woman who had ever accomplished her greatest feat. Every new-born baby that had ever been born, potential in their eyes. I experienced every sensation that could ever be felt, and saw every note that had ever been played, I tasted success, I smelled hope and in all of these things combined I saw the face of God. I awoke in my bed and questioned my own existence again. As I write this I am still unaware of what my dream means. I believe that we are more than skin and bones. I believe that our bodies are nothing but vessels, and I believe that our souls are always yearning to escape them. I am unsure of the afterlife, and I wonder whether or not this life on earth is simply the afterlife to a previous one; that maybe every life is an afterlife and in each one we are promised something different for the next. I wonder how many times I have died before, I wonder how many times I will die again, and I wonder whether or not there is some end to this cycle. The only thing we can be sure of is death, for without death there is no life. There cannot be one without the other, but I do not believe that birth is the beginning and death the end. Until it is my time to become knowledgeable of what is next to come, I will just keep dreaming.

The University Should Raise Tuition Each Year Essay -- Argumentative P

The University Should Raise Tuition Each Year Tuition usually increases once a year, for the main purpose that schools go over their budget and they have to make up that money in some way. The schools are using that extra money to make that school a better place so that existing students and new students think its worth spending their money on, going there for a higher education. There are good and bad things about tuition increases, but the big thing to think about is, are these increases going to help the students? Yes, they are, the schools are increasing tuition so that the students can get there higher education, and feel that they are getting it at a great place. Schools want to help their students get the best higher education they can, but to do that, they have to raise tuition so they can afford to help their students. Universities have budgets which they are supposed to stick to, and now that they are not sticking to them, they need to raise tuition so that they can make up for the extra money that they spent. â€Å"The University of Virginia saw a 20 percent cut in their tuition bill in 1999, is planning a midyear tuition surcharge as bad state-budget news continues to poor in,†(Hebel, 2002). Universities are having a very hard time with their budgets that they need to raise tuition. There is a really good question to ask, why are they going over their budgets? There are many answers to that question, one of them is that the government isn’t giving universities as much money as they used to, another answer is that, they have so many students paying to go to their school, that they feel that they have to keep them there, so they spend money improving programs to help their students get the higher education ... .... This way the students get their higher education, and better programs to help them achieve that higher education. Programs such as tutoring really do help students with their classes, and help keep their grades up. Some students have scholarships, and without good grades, they loose their scholarships. As long as raising tuition helps the students, it’s a good idea. Otherwise, they should think about leaving the tuition alone or putting some of that extra money into some new or existing programs. This way, the students know where their money is going; doing this will help students be ok with the idea of tuition increases. If the students are fine with the idea, then it won’t be such a hardship retaining more students and keeping the existing students, because the students are getting something for their money, not just a higher education, but programs and help.

Handspring INC Evaluation and Control :: essays research papers

Solution EVALUATION AND CONTROL Evaluation of the sales staff should be done in order to improve their performance. Targets should be set at the beginning of every month and the actual performance in relation to the targets should be compared to get the real difference between the targeted performance and the real performance. A similar, target setting and evaluation of the sales performance will not only evaluate the performance of the employees but will also control them effectively. Remember, the yearly increments and promotions will to an extent depend on the performance of the sales personnel. This will help the company meet its sales objectives. Evaluation of the research & development staff is necessary to make Handspring products technically superior to that of competitors. For instance if the objective of the personnel is to develop products that are compatible with the operating system of Microsoft, then they have to be given objectives relating to the technical development of the product, the time deadline they have and the cost constraints. The R&D staff would be given a priori evaluation. That means that before the work starts on the project, the values attached to the various stages of the work would be decided. For example, if the work were to be completed on time, it would be given a rating of 5 and if the work were 80% complete the rating would be 4 and so on. This a priori contract would not only impose a control on the work but would help Handspring achieve its strategic objectives. For example, if the strategic objective of Handspring were to reduce the cost of Treo, then this project would be given to a projec t team with a fixed time period and a set of objectives. Setting up of objectives and entering into an a priori contract with them so that their performance can objectively be evaluated can do evaluation of the top managers also. For, example one of the vice- presidents can be entrusted with the task of setting up alliances with other top companies so that Treo is purchases as a tie up product. The vice-president will be given a target of forging say 6 alliances having a sale value of $XXM. Apart from this other criteria for his evaluation can be set up and each given a weight. At the end of the evaluation period the actual performance of the vice-president will be compared to the targeted performance and a composite score calculated for him.

What Important Lessons in Life Are Learned Away from School?

Education plays a pivotal role in the life of any person. Some think that learning is done primarily in school. It is true that educational institutions have been so entwined with the process of learning where students learn languages and a variety of other subjects to learn how to communicate and analyze. However, important lessons outside school are also important to develop skills in us to prepare us for the future. One of the most important lessons that school cannot teach is morality. School cannot and will not be the yardstick of right and wrong.To be a person of integrity, one could probably attend a religious institution and learn the principles of upright living. To be morally upright would definitely help one to be a better person and grant him the inner peace that he needs for daily living. Living by the religious principles such as the Proverbs in the bible would also be able to guard him from committing follies that can be avoided. Another important lesson that one can l earn outside school is the skills of financial planning. Although school teaches the calculation of figures, it does not teach us how these figures would affect us financially in our lives.By learning to budget wisely, one would not end up in unnecessary debts. It is not uncommon to find young adults under a huge credit-card debt. To avoid such dire situations, one needs to learn the discipline to save, invest and spend wisely so that there will be wealth accumulation and funds set aside for a rainy day. Beside financial planning, we must learn lessons of hardship and perseverance. Without such values, one would be easily set back by failures. Hence, taking vacational jobs to earn some pocket money is an excellent opportunity to learn how to withstand hardship.For example, I was employed as a waiter in a five-star hotel. Having to stand daily for hours has taught me to take hardship in good stride. Such lesson would not have been made possible in school where children learn academic success above anything else. Finally, the school usually does not teach us the skills of widening and deepening friendship. Learning the right communication skills and the social boundary that we should keep between friends will enable us to understand and appreciate our friends better.A widening social circle and an inner sphere of intimate friends are important to help one succeed in life. A friend can be there to give advice, provide business opportunities and even provide a listening skill. Unfortunately, the school does not provide such skills and this could only be learnt from home and interaction with the outside world. In conclusion, it is a fallacy to think that everything can be learnt in school. One should always display a willingness to learn and relearn out of school context to be able to strive and thrive in this changing world.
