Examining The Examples Of A Tragic Hero English Literature Essay Free Essays

A premier illustration of a tragic hero is John Proctor, from Arthur Millers, The Crucible.A Proctor is easy placed in this class of heroes because he has features that define who may be considered such a hero, such as the fact that he is extremely regarded in the community, that he has a tragic defect, that he dies and embraces decease with self-respect and that he is portrayed as a human being like his readers to which causes a katharsis of emotions in them. Leon Golden writes that â€Å" the ideal Aristotelean form of tragedyaˆÂ ¦ the autumn from felicity to wretchedness, caused by a serious rational mistake, on the portion of a hero who is worthy of regard†¦ † ( Golden ) . We will write a custom essay sample on Examining The Examples Of A Tragic Hero English Literature Essay or any similar topic only for you Order Now John makes such â€Å" mistakes † due to his tragic defects, which result in his ruin, but in malice of these defects in his character, he is extremely regarded within his community. He makes a serious mistake in judgement, realizes that he has made an irreversible error, and while he recognizes that he must be put to decease, maintains his self-respect and trades with his destiny with a step of credence, like a tragic hero is supposed to make. Finally, John has the intrinsic ability to pull out sympathy and commiseration from his readers which is besides a celebrated quality of the authoritative tragic hero. John Proctor is hence the quintessential illustration of a tragic hero.A It is apparent early on thatA John ProctorA wasA extremely esteemed within the community, A because heA wasA called toA Reverend Parris ‘ family toA see howA the Reverend ‘s ailment daughterA was making. The rigorous Puritan members of Salem besides commended him for hanging the door of the church.A Despite the strength in which the Puritans regarded their faith and the contempt they shared for those less â€Å" spiritual † than they were, Arthur Miller writes that â€Å" Proctor, respected and even feared in SalemaˆÂ ¦ † ( Miller 20 ) . John ProctorA wasA still considered to be an honest, hardworkingA adult male and aA God-fearingA Christian, even though he did n’t go to church and was non, in any manner, perfect. James Martine suggests that â€Å" the ideal supporter of calamity, so, says Aristotle, must be a adult male like ourselves, one who does non possess righteousness and virtuousness to flawlessness, but whose character is held in high-esteem by all † ( Martine ) . Therefore, Proctor fits the portion of Aristotle ‘s tragic hero definition which claims he must be a well-respected individual within the narrative ‘s chief community ( even if he is non near to being Godhead ) . However, as is the instance for every tragic hero, a tragic defect that John Proctor possesses finally led to his tragic terminal. One of John Proctor ‘s tragic defects was his unfaithfulness. Like Larry Brown believes, â€Å" Miller created the matter between Proctor and Abigail as a cardinal motivational factor in Proctor ‘s character † ( Brown ) . Because of the matter he pursues with 17 twelvemonth old, Abigail, the remainder of the events that lead to his day of reckoning unfold. Abigail ‘s green-eyed monster of Proctor ‘s married woman, Elizabeth, cause her to get down a commotion in Salem and to impeach people of take parting in witchery because she believes if she removes Elizabeth, by impeaching her of being a enchantress she could hold the desirable John Proctor all to herself.A Another defect of Proctor that consequences in his decease is his pride. Martine agrees that for a hero to be considered tragic, â€Å" the hero must be a extremely moral person who has a tragic defect, a tragic flaw. This defect is frequently hubris-commonly characterized as prideaˆÂ ¦ † ( Martine ) . Proctor is delayed in the confession of his wickedness because it is of extreme importance to him to keep a good name. Had he owned up to the matter earlier on in the procedure, he could hold shown the tribunal that Abigail had a sensible alibi and the whole events of the Salem enchantress tests could hold been stopped before they even began. Because of John Proctor ‘s serious defect in character and his awful wickedness, he is hanged upon the gallows of Salem for all to see. Not many people accept decease with such awards and unity as Proctor does. A Out of self-respect and pride in his household and himself, John Proctor decides to be hanged instead than lie and falsely confess to hold practiced witchery and everlastingly be associated with it. Proctor, in mention to the prevarication that subscribing his confession would be, says â€Å" Because I can non hold ano ther in my life! Because I lie and sign myself to prevarications † ( Miller Act IV ) . In add-on, he does non desire to subject to the giving over of names of other people in the community, feigning that they were enchantresss, to acquire himself off the hook, or in this instance, gallows. â€Å" The tragic terminal of the drama comes at the really point where Proctor found his morality and award that he thought he lost † ( University of Houston- Clear Lake ) . The pride that led to Proctor ‘s ruin is the same pride that causes him to decease in self-respect, without subscribing to prevarications. John Proctor hides his criminal conversation with Abigail from the tribunal for the interest of repute, until he must squeal: â€Å" I have made a bell of my award! I have rung the day of reckoning of my good name. † However, as he is pressured to curse falsely that he dealt in witchery, Proctor realizes it is his name in the sense of personal unity, being true to himself, non his repute among others that affairs most of all ( Brown ) . The concluding facet of a tragic hero that John Proctor undoubtedly encompasses is his relatability, which causes the other characters in the drama and its readers to sympathize with him. Proctor is displayed as a mere human being with defects and battles which in many ways mirror our ain defects and battles. â€Å" This deep-rooted temperament of ‘frailty ‘ is Proctor ‘s ain indispensable humanity and demonstrates him to be ‘a adult male merely like ourselves. ‘ And since this is so, the attendant katharsis arouses, and purgings, our ain commiseration and fright † ( Martine ) . Some of his greatest battles are happening himself and covering with the guilt he feels for holding an matter, which he finally comes to accept as Martine says ; â€Å" John Proctor is heroic because he accepts his guilt and indicts the society that would coerce him to give over his scruples. To make both, he must be self-discovered, self-recognized and eventually self-ac cepting † ( Martine ) . Proctor is at his tallness of ego consciousness when he realizes how of import it is to keep his unity. Robert Heilman explains that Shakespeare made the tragic hero, â€Å" a figure capable of self-awareness and self-judgment † ( Heilman ) . Just as Miller gave John Proctor the ability to hold self-awareness, William Shakespeare gave his tragic heroes the same ability. Because the readers find themselves similar to Invigilate in that they besides are flawed, they are able to to the full sympathize with him and throw themselves into the emotional convulsion of the narrative. Therefore, when the narrative of John Proctor is read, the reader experiences a katharsis of emotions. They feel fear for him, throughout the tests and when his destiny is being determined. They feel sympathy for him as he approaches his decease, right after he and Elizabeth eventually mend their matrimony. A narrative of a tragic hero tends to accomplish that consequence on its readers. How to cite Examining The Examples Of A Tragic Hero English Literature Essay, Essay examples

Roles of women in the Iliad free essay sample

In The Stories The stories depending on great love are generally seems a charming narration for readers and listeners. And also women used in the such stories are generated with sensous motifs. However,we can confortably realize that roles of women in the most known two ancient stories,The Epic of Gilgamesh and The Illiad,are considerably different. While these texts lack a female love interest,erotic love still plays an important role as women figures. When reading The Epic of Gilgamesh , we can encounter the effections of women that change the flow of the story ,yet at the same time , none of them are depends on emotional reasons. According to first written epic,The Epic of Gilgamesh, â€Å" participation of Enkidu into humans occurs thanks to sexual ability of a prostitute. In this situation,making sex with women is used as forces that could civilize the wild men like Enkidu and bring them into the civilised society †(12-17). We will write a custom essay sample on Roles of women in the Iliad or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page In the another notable example from The Epic of Gilgamesh , â€Å" the king of Uruk ,Gilgamesh, taking the wifes from among his folk for his fantacy when their first wedding day†(19-23). There is also one more important example to show reflection of women on that times , â€Å" Ishtar , the goddess of love , shows her erotic desire to Gilgamesh but Gilgamesh refuses her because of Ishtar ‘s obsessive erotic background with previous men and this situation results with the death of Enkidu†(47-55). While we analyze the relationships between men and women in the story, easily saying that roles and behaviors of women have remarkable importance to the flow of story though there is no love figures for women in these situations apart from sexuality and eroticism. Examples shows that women did not mean love for men on that times although they become important figures changing situations. â€Å" The other famous story ,The Iliad , begins with conflict between Agamemnon and Achilles because of prices of war, Chryseis and Briseis. On the following pages Helen , the reason of the war between Achaeans and Trojans , is also used as a price of the fight between Paris and Menelaus â€Å"(80-96). We can say that women were used as slaves and deserved prices for men living on that times depends on these examples. Moreover, relationship between Helen and Paris which is known as a great love by readers and listeners was not actually well-grounded because â€Å" Helen ,a figure of this love , blames Paris and wishes him died there and also more suprising thing is answer of Paris. He demanded sleeping with her even if Helen do not want to be with unhonorable Paris†(140-144) . As a result of above ,women using in The Iliad do not contain overtones of emotional love . To sum up , roles of women that is used in both stories do not bear any emotional motifs for men even if their entity plays important roles in the stories. When analyzed the women in that stories ,our interest are focused on two specific results,either love was just sexual and erotic feelings or the women did not have importance taking their own roles in societies to loved by men on that times .

How Chromosomes Determine Sex

How Chromosomes Determine Sex Chromosomes are long segments of genes that carry hereditary information. They are composed of DNA and proteins and are located within the nucleus of our cells. Chromosomes determine everything from hair color and eye color to sex. Whether you are a male or female depends on the presence or absence of certain chromosomes. Human cells contain 23 pairs of chromosomes for a total of 46. There are 22 pairs of autosomes (non-sex chromosomes) and one pair of sex chromosomes. The sex chromosomes are the X chromosome and the Y chromosome. Sex Chromosomes In human sexual reproduction, two distinct gametes fuse to form a zygote. Gametes are reproductive cells produced by a type of cell division called meiosis. Gametes are also called sex cells. They contain only one set of chromosomes and are thus said to be haploid.The male gamete, called the spermatozoan, is relatively motile and usually has a flagellum. The female gamete, called the ovum, is nonmotile and relatively large in comparison to the male gamete. When the haploid male and female gametes unite in a process called fertilization, they develop into what is called a zygote. The zygote is diploid, meaning that it contains two sets of chromosomes. Sex Chromosomes X-Y The male gametes, or sperm cells, in humans and other mammals are heterogametic and contain one of two types of sex chromosomes. Sperm cells carry either an X or Y sex chromosome. Female gametes, or eggs, however, contain only the X sex chromosome and are homogametic. The sperm cell determines the sex of an individual in this case. If a sperm cell containing an X chromosome fertilizes an egg, the resulting zygote will be XX, or female. If the sperm cell contains a Y chromosome, then the resulting zygote will be XY, or male. Y chromosomes carry the necessary genes for the development of male gonads, or testes. Individuals that lack a Y chromosome (XO or XX) develop female gonads, or ovaries. Two X chromosomes are needed for the development of fully functioning ovaries. Genes located on the X chromosome are called X-linked genes, and these genes determine X sex-linked traits. A mutation occurring in one of these genes could lead to the development of an altered trait. Because males have only one X chromosome, the altered trait would always be expressed in males. In females,  however, the trait may not always be expressed. Because females have two X chromosomes, the altered trait could be masked if only one X chromosome has the mutation and the trait is recessive. An example of an X-linked gene is red-green colorblindness in humans.   Sex Chromosomes X-O Grasshoppers, roaches, and other insects have a similar system for determining the sex of an individual. Adult males lack the Y sex chromosome that humans have and have only an X chromosome. They produce sperm cells that contain either an X chromosome or no sex chromosome, which is designated as O. The females are XX and produce egg cells that contain an X chromosome. If an X sperm cell fertilizes an egg, the resulting zygote will be XX, or female. If a sperm cell containing no sex chromosome fertilizes an egg, the resulting zygote will be XO, or male. Sex Chromosomes Z-W Birds, some insects such as butterflies, frogs, snakes, and some species of fish have a different system for determining sex. In these animals, it is the female gamete that determines the sex of an individual. Female gametes can either contain a Z chromosome or a W chromosome. Male gametes contain only the Z chromosome. Females of these species are ZW, and males are ZZ. Parthenogenesis What about animals like most kinds of wasps, bees, and ants that have no sex chromosomes? In these species, fertilization determines sex. If an egg becomes fertilized, it will develop into a female. A non-fertilized egg may develop into a male. The female is diploid and contains two sets of chromosomes, while the male is haploid. This development of an unfertilized egg into a male and a fertilized egg into a female is a type of parthenogenesis known as arrhenotokous parthenogenesis. Environmental Sex Determination In turtles and crocodiles, sex is determined by the temperature of the surrounding environment at a specific period in the development of a fertilized egg. Eggs that are incubated above a certain temperature develop into one sex, while eggs incubated below a certain temperature develop into the other sex. Both males and females develop when eggs are incubated at temperatures ranging between those that induce only single-sex development.

Public Health Law reform Essay Example | Topics and Well Written Essays - 250 words

Public Health Law reform - Essay Example The proposed public laws are crafted to link various three aspects, duty, restraints and power, this are fundamentally missing in the current statutes necessitating the need for the revised form (Novick, Morrow, & Mays, 2008). On duty, the envisaged law compels the government to give priority to the well being of the citizens in promoting dissemination of health services in a non-discriminatory. Interestingly, the state government does not have any affirmative action in the implementation of the policies and this transcends to the judicial systems that lacks clear guidelines on how to apprehend violators of these statutes. These are some of the issues addressed in the new model of the laws. The government should also be given the powers to set the required standards of health and enforce these laws to avoid defaulters getting away with such offences. The regulations in this case rotate on issues like clean water, air and work places to mitigate on the spread of infectious diseases ( Novick, Morrow, & Mays, 2008). The new proposals also endeavor to check on the government involvement in the assessment of these acts such that possible unfair intrusions can be regulated. Even with the drafting of the new reforms, there has been no unanimous public agreement with the reforms and contentious issues are yet to be sort for its implementation (Novick, Morrow, & Mays,
