English 102 Professor Su Suoccai Arnaud Fragniere 19 February 2014 The different aspects of the Grandmother’s personality in ’’A Good Man Is Hard to Find’’ In Flannery O’Connor’s story ‘’A Good Man Is Hard to find’’, the author narrates the events as a third person, centering it on the grandmother who decides to go with her whole family for a road trip from Georgia to Florida. The grandmother does not want to go to Florida. During the journey she selfishly and manipulatively forces the whole family to go see a plantation that she mistakenly think is on the way. This results in them having an accident and meeting the Misfit, an extremely violent criminal who defies ‘’the beliefs that Christians have in the ability of Jesus to raise the dead’’. As the story develops, the Misfit and his accomplices kill all members of the family except for the grandmother, who up to her death, falsely tries to convince herself and the Misfit that he is a ‘’good man’’. At the end, the grandmother has a moment of grace. However, it proves unavailing as the Mis fit, proceeds to kill her without remorse. Throughout the text we realize that the major trait of the grandmother’s personality is the fact that she considers herself as morally superior. This is based on her belief that she is a ‘’lady’’; sophisticated, wealthy, overall better of a woman. In her eyes, this allows her to judge others. Not only does she see herself as superior, but she thinks that her faith along with her being a good Christian would save her from anything that could cross her path. We discover that she is also extremely selfish and manipulative; for her, her life has much more value than anything else, including the life of her children and grandchildren. To unders... ...e times through the chest. The grandmother’s selfishness and ability to manipulate people fails to help her during the biggest threat that she has to face through her entire existence: her imminent death. Her inability to change the Misfit’s mind and manipulate him the way she wants costs her life. O’connor’s story shows us an old grandmother who considers her as a superior person being powerless against her antagonist in life. The Misfit, this criminal who doesn't believe there is real pleasure in life challenges everything the old lady might say or do in order to live. The old lady tries in vain to save her life using all the tools that she knows, even if she selfishly has to serve this purpose and letting her whole family get killed. The grandmother must abandon all of her manipulative self-absorption, her focus on class and her external show of Christianity.

Political Cartoon Assignment Essay

The political cartoon that I chose mainly aims towards people who are concerned about the environment and people who are against The American Clean Energy and Security Act. An every day citizen may not get the entire meaning of the cartoon if they do not know the motive behind it or do not follow politics and environmental news. The cartoon is political because it clearly states two things that weigh heavily on the minds of the public right now: tax and the environment. While this doesn’t typically necessarily mean that a cartoon would be political, the word â€Å"bill† on the page in the man’s hand points in the direction of political. The cartoon effectively shows two sides of the issue: one where the public is being told that the bill would cause a tax increase that the American consumers would ultimately have to deal with and another side where the environmentally-conscious person is saying that it’s just a scare tactic and that it would cause more good than harm for the country. At first glance, the cartoon was humorous, but the more I looked at it and began to understand what it was talking about, my thoughts began to change. Although it’s still funny, the cartoon carries a deeper meaning than just entertainment. The main thing that I felt was slight irritation that people could think that there are only two ways of looking at the issue and that people could be so concerned about taxes that they don’t even think about the environment that we’re living in. Although what is being shown is comical, the emotions behind what the artist is trying to show the viewer is not. Even if he shows that there are two sides of the issue, he still wants you to realize that economists are using the current state of the economy to play on your emotions and try to convince you that you’re ultimately hurting yourself by supporting the bill. Whether or not the artist was successful in the attempt to persuade the viewer into a way of thinking is up to the interpretation of each individual person. For me, it was successful. I was able to see the two different sides of the issue and while I understand both, I was able to draw my own conclusion and say that there needs to be some sort of middle ground. In part, the artist wants you to see how you’re being manipulated by the economists and the people that are against the bill to believe that the bill will have more of an impact on your bank account in terms of more taxes rather than having a good impact on the environment. Although I’ve always known that there are people who are against the bill, before seeing it in cartoon form, I never really realized that they really might be just a way of making people choose one or the other; the environment or your money. In terms of opening my eyes, the artist was successful.

A Twentieth Century War Was Just and a Holy War Essay

A Twentieth Century War Was Just and a Holy War On 2nd September 1939, Britain and France declared war on Germany. Wars are started for many reasons, but can they ever be justified? This essay will analyse whether the factors causing the Second World War were justified. Augstine, a Christian leader in the Middle Ages, devised the Just War Theory. The Christian thinker Thomas Aquinas then adapted this theory, which then formed the basis of the UN conditions for a just war. To assess whether a war is justified the Just War Theory criteria need to be fulfilled. They0 and are shown below: 1.) There must be a just cause. Those attacked must have committed some fault. 2.) The war must be†¦show more content†¦You must only use enough force to achieve your objectives. As far as possible, only military people, and not civilians, must be involved. The first criterion is that of a just cause. In this case, it can be considered that Hitlers invasion of Czechoslovakia and Poland meets this criterion. Britain saw these invasions not only as a threat to those countries but to the rest of Europe and Britain itself. Secondly, the war must be started and controlled by a competent and legal authority, suitably the British government. This implies that wars started by small groups or factions with self-interest are unjust and the authority of the government ids required because the whole country is involved. Parliament should approve it because parliament is representing the people. The war must also be right intention, in this case to avoid the greed and evil nature of Hitler and to promote the fair, democratic rule of Britain and France. The fourth criterion is that the war must be a last resort; it can be argued that Britain and France tried the Policy of Appeasement. A policy when they stood back and didnt do anything. but these methods of averting the war had failed and it became obvious that if they didnt act, Hitler would take over France and in possibly eventually Britain. In addition, there must be a reasonable probability of success.
