The Redeeming Features of the Characters in Electra Essay -- Euripides

The Redeeming Features of the Characters in Electra       In Euripides' 'Electra', there are a number of parts, speaking and non-speaking, that reveal the redeeming features of the otherwise pitiful characters. This essay will consider the roles of Orestes, Electra, Clytemnestra, the Peasant and Aegisthus (whose actions are only reported to us).    It is arguable that the characters are not redeemable due simply to the plot of the play: a son returns, kills his father's unworthy successor, his mother (with the aid of his sister) and was sent away at the end of the play by divine judgement. His sister assisted him in the matricide and is sent away also. However, it is unrealistic for all the characters of a tragedy not to have any good qualities. The nature of tragedy, according to Aristotle, is to invoke pity ('kitharsis'), cleansing the soul - this can not be invoked if the characters are bad people, since we will feel no pity. Aristotle described Euripides as "the most tragic of the poets..." so it is likely for the playwright to conform to Aristotle's' rules for tragedy. Bad happenings ('hamartia') are required to happen to good people, who may not be entirely noble but are still respectably good. For example, in Oedipus Rex, Oedipus scorns the prophecies of Apollo but he is a noble King, who feels compassion for his people and his destined blow was only the result of his uninformed actions.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Orestes is the avenging son of Agamemnon, returned to his homeland. We would expect this man to be the tragic hero of the play but he does not conform to the specifications. He is not a powerful character and is constantly in need of guidance, acting simply as a loaded cannon ("What do you suggest?"). When ... ...er in the play's duration, with a history of murder that seems disconnected from this person as we see her. Finally, Aegisthus, though amiable to his guests, has an undeniable history of murder and the people are happy to see him go. If he does have redeemable qualities, they are few.    Works Cited Euripides. Electra. Trans. Philip Vellacott. Medea and Other Plays. Baltimore: Penguin Classics, 1963. 105-152, 201-204.

Sport as Solvation to Reduce Stress

Stress is generally known as a reaction, or a natural system defender. In mostly recognized situations, stress can be annoying, disturbing, and the detach from activity. Most of our generation tends to work, and the same amount works in the service industry. We do not however realize how much, or how long per week we should work. Usually the working hours combines between 35hpw and 45hpw, but in many cases this is the rule which just the contract contains. The general definition is â€Å" working longer means earning more†, so people do, and reach absolutely records of â€Å"long hours „of work such as 60/70hours per week. In return we collect few more coins, and extremely high level of stress, which reflexes at our homes, and on our health condition. This is just a little step forward to achieve mental disaster, to ruin home stabilization, or simply get a heart attack. Do we want this? To keep ourselves up and running, we could set our day with some sport activity, which in my opinion is the best solution for any kind of stress. First of all, it will drug as out from the habit being at work, at home and work again, so look around you neighborhood to find a swimming pool or gym. Then join it and try to get there for at least twice a week at beginning. No one sais to lift the heaviest weights, but analogically you will find it relaxing. Exactly the same with swimming pool or any other kinds of sport such as running. Do not try to overwork and the result will be guaranteed. You start to sleep better, your concentration will improve, and after sometime you want be able to leave without it. Its hard to break habits, but remember, nothing last for ever, and especially our health. There are money to earn, but no health. If you wish to end up as ailing in your early forties, forget about the sport activity and keep working as crazy, however you want appreciate the fact of earned money because you will spend them for medical treatment.

Chicana Feminist Writer Gloria Anzaldua

Feminist Gloria Anzaldua was a guiding force in the  Chicano and Chicana movement  and  lesbian/queer theory.  She was a poet, activist, theorist, and teacher who lived from September 26, 1942, to May 15, 2004. Her writings blend styles, cultures, and languages, weaving together poetry, prose, theory, autobiography, and experimental narratives. Life in the Borderlands Gloria Anzaldua was born in the Rio Grande Valley of South Texas in 1942. She described herself as a Chicana/Tejana/lesbian/dyke/feminist/writer/poet/cultural theorist, and these identities were just the beginning of the ideas she explored in her work. Gloria Anzaldua was the daughter of a Spanish American and an American Indian. Her parents were farm workers; during her youth, she lived on a ranch, worked in the fields and became intimately aware of the Southwest and South Texas landscapes. She also discovered that Spanish speakers existed on the margins in the United States. She began to experiment with writing and gain awareness of social justice issues. Gloria Anzaldua’s book Borderlands/La Frontera: The New Mestiza, published in 1987, is the story of existence in several cultures near the Mexico/Texas border. It is also the story of Mexican-Indian history, mythology, and cultural philosophy. The book examines physical and emotional borders, and its ideas range from Aztec religion to the role of women in Hispanic culture to how lesbians find a sense of belonging in a straight world. The hallmark of Gloria Anzaldua’s work is the interweaving of poetry with prose narrative. The essays interspersed with poetry in Borderlands/La Frontera reflect her years of feminist thought and her non-linear, experimental manner of expression. Feminist Chicana Consciousness Gloria Anzaldua received her bachelor’s degree in English from the University of Texas-Pan American in 1969 and a master’s in English and Education from the University of Texas at Austin in 1972. Later in the 1970s, she taught a course at UT-Austin called â€Å"La Mujer Chicana.† She said that teaching the class was a turning point for her, connecting her to the queer community, writing and feminism. Gloria Anzaldua moved to California in 1977, where she devoted herself to writing. She continued to participate in political activism, consciousness-raising, and groups such as the Feminist Writers Guild. She also looked for ways to build a multicultural, inclusive feminist movement. Much to her dissatisfaction, she discovered there were very few writings either by or about women of color.   Some readers have struggled with the multiple languages in her writings – English and Spanish, but also variations of those languages. According to Gloria Anzaldua, when the reader does the work of piecing together fragments of language and narrative, it mirrors the way feminists must struggle to have their ideas heard in a patriarchal society. The Prolific 1980s Gloria Anzaldua continued to write, teach, and travel to workshops and speaking engagements throughout the 1980s. She edited two anthologies that collected the voices of feminists of many races and cultures. This Bridge Called My Back: Writings by Radical Women of Color was published in 1983 and won the Before Columbus Foundation American Book Award. Making Face Making Soul/Haciendo Caras: Creative and Critical Perspectives by Feminists of Color was published in 1990. It included writings by famous feminists such as Audre Lorde and Joy Harjo, again in fragmented sections with titles such as â€Å"Still Trembles our Rage in the Face of Racism† and â€Å"(De)Colonized Selves. Other Life Work Gloria Anzaldua was an avid observer of art and spirituality and brought these influences to her writings as well. She taught throughout her life and worked on a doctoral dissertation, which she was unable to finish due to health complications and professional demands. UC Santa Cruz later awarded her a posthumous Ph.D. in literature. Gloria Anzaldua won many awards, including the National Endowment for the Arts Fiction Award and the Lambda Lesbian Small Press Book Award. She died in 2004 from complications related to diabetes.
