Dulce Et Decorum Est Essays (618 words) - Dulce Et Decorum Est

Dulce Et Decorum Est Explication of ?Dulce et Decorum Est? In his poem exhibiting the gruesome imagery of World War I, ?Dulce et Decorum Est?, Wilfred Owen conveys his strongly anti-war sentiments to the reader. Through the irony found in the ending, horrific imagery, and the feeling of surrealism woven into the poem, Owen forces the reader to experience the war, and therefore feel almost as decisively about it as he does. Owen applies the rhetorical situation, sensory imagery, and figurative language to contribute to the power and anti-war sentiment of the poem. The rhetorical situation in the poem helps to make the reader accept the poem's message by showing that the speaker may be trusted to be knowledgeable about the subject at hand. The poem would be far less effective had the speaker not personally experienced the vicious and cruel world war provides. Another effective element of the rhetorical situation is that the audience addressed in the poem is the person who would not tell with such high zest/ To children ardent for some desperate glory/ The old lie (25-27) if he himself had been to war. The speaker has been robbed by the deceitful notion of the sweetness of war; childhood and innocence are no longer fathomable. Essentially, the poem becomes an accusation and the reader, like a bell, can clearly hear bitterness in the speaker's voice for having been deceived so greatly. Owen uses paradoxical sensory imagery to communicate his early illusions of war's heroic glory soon dissolving into a hellish reality. The speaker in the poem must distance himself from the pain and suffering before his eyes, and so he turns away from the haunting flares (3). The phrase blood shod (6) early in the poem is an example of the contradictory truths of war- soldier's boots are made to protect his feet from pain and injury. In this instance, however, Owen compares the feeling of protection with the appalling image of bloody pain to express the irony and senselessness in war. With gas shells dropping softly behind (8), the word softly appeals in a positive manner to our tactile and auditory senses, yet this is being said about lethal weapons. In this image, Owen again presents an unexpected and paradoxical picture of war. The speaker, emphasizing that he is behind misty panes (13) as he witnesses the dramatic and grotesque death of another soldier, spares no detail, leaving the reader to deal with sudden, shocking emotions summoned in response to the sensory horror. The figurative language in the poem allows the reader to share in the speaker's sense of open-mouthed wonder at the situation. Owen states that Men marched asleep (5): a virtual impossibility, the metaphor represents the complete exhaustion endured by the soldiers. The green sea (14) of gas in which the soldier is drowning (14) depicts the dreamlike circumstances as the speaker perceived them- similar to the alseep metaphor, where only in an alternative reality state would the atrocities of war be tolerable. The incurable sores on innocent tongues (24) declare the absurdity and injustice of war. Owen's figurative language highlights the complete irrationality of war with an austerity that gives the poem much of its irrefutable power. Owen clearly communicates his aversion to war through the use of the rhetorical situation, sensory imagery, and figurative language in his poem. Not only does he covey his own feelings through the speaker, but he also succeeds in inspiring similar feelings in his readers by forcing them to encounter the horror of war. Through all of the above devices, Owen's poem Dulce et Decorum Est conveys its purpose to the reader in a thunderous and powerful voice. Bibliography none necessary Poetry Essays

A Hero Like a Hurricane

A Hero Like a Hurricane “Im your RA Katrina, like the hurricane,” she had said when we first met. It sounded strange, a bit intimidating even. Stranger still was her first piece of advice, a warning to shave our heads while were still young. She was blunt, yet not offensive; confident, yet not arrogant. Even when she didnt speak a word, her presence was always unconsciously pronounced and obvious. Her enthusiastic words of encouragement and acts of selflessness, even the smallest ones, became a source of great inspiration and helped to broaden my opinions.During conversations, Katrina usually got very quiet, subliminally signifying to us that she was trying to analyze everyones opinions and personalities. She always had the last word and concluded every conversation. Her presence and humility always were clearly prominent.I still remember one night when I foolishly locked myself out of the dorm at midnight and had no other choice but to ask for Katrinas assistance.2005-8-25 Hurricane KatrinaAlthough she had just awoken, her response was swift and she quickly made her way three floors down to the far side of the building to retrieve a spare key. Perhaps she was just doing her job, but there have been other occurrences where other RAs were not as selfless and ignored their students to gain some sleep.Next year, Katrina is fulfilling her dream by joining the Peace Corps, traveling to Africa, and shaving off all her shoulder-length red hair. Her selfless goals to better the environment and her determination to achieve them, inspires me to make similar goals. As her last piece of advice, Katrina hoped to inspire us further, telling us to never waste our “one wild and precious life.”My admiration for someone only seven years older than me grew not only because of her selflessness but also from...

Discuss some of the benefits and drawbacks of studying for a Essay - 2

Discuss some of the benefits and drawbacks of studying for a university degree, Which appear to be more persuasive Refer to the text and other sources - Essay Example Not only does a degree from a university improve a person’s career prospects but it also helps him socially. His societal status improves and he is respected more. Saying that, however, does not mean that attaining a university degree is a sure shot at landing at your dream job. It is very commonly seen that graduates are jobless or working at a lowly position which is not what they had in mind when pursuing their degree. The value of a university degree should not be gauged monetarily only although that is what most people do and high paying jobs are why people pursue a degree. A university degree gives other possible benefits as well that will be detailed in the rest of this paper. Nevertheless, a degree is never a waste of investment and even if a person does not end up getting a job right away he will find that later on, when he has some experience in lowly jobs, his degree is what will set him out from non-graduates and help him get a good job. I am a single mother of four, having lost my husband a year back. I have a background in nursing and 15 years of experience in the same field. Now I have decided to move into Public Health. I am currently enrolled in the program and also working a part time job side by side. The reason I decided to pursue this degree is that I have a passion for academics and I believe that it will help me a lot in climbing up my career ladder. Yes, it is a pretty hard task managing studies, work and a family and yes, it is extremely difficult to give equal time to all, not to mention it becomes very tiring and stressful too. But then, if you want to achieve something you have to sacrifice and work hard for it. I have also planned to complete my university training as that will be counted a lot. Training and experience is always a bonus in professional life. I believe that once I have this degree I can apply for a better position and be able to earn and support my family better. Even if the results

Using evolutionary psychology to develop your own prediction about Essay

Using evolutionary psychology to develop your own prediction about communication - Essay Example He believed that laughter could be a sign of genetic fitness that attracts the opposite sex. What is not yet fully known is why men, in particular, are attracted to women’s laughter. The question is: Why can laughter make a woman attractive to men? The false alarm theory and sexual selection theory can be both used to explain why women’s laughter attract men. The false alarm theory states that people laugh to show that any possible anomaly or threat in the environment is not present (i.e. the initially thought of as an anomaly is a false alarm) (Ramachandran, 1998, p.352). It explains that laughter assures others that harm is not present in the environment, which also partially explains why laughter is done more when people are around than when alone (Provine, 1996). In connection to laughter, false alarm theory suggests that women laugh to signal that they are not in danger. They laugh when they are with men because they want to make sure that resources are saved by not sending an incorrect alarm signal. The second theory is sexual selection theory that states that laughter is attractive because it is a sign of fitness. My hypothesis is that women laugh to signal that they are not in harm’s way. This means that laughter reduces risks or perceptions of harm to men. At the same time, women laugh to show that they can take care of their children well because laughter is related to genetic fitness (Bressler & Balshine, 2006). Men are attracted to women who laugh because of lower threats in the environment and perception of women’s genetic fitness. My prediction is that men like women who laugh because the latter’s laughter signal lack of danger and ability to protect their offspring. Women’s ability to expel noise through laughter, is an indicator that they are good sexual mates because they are good mothers. In other words, when women laugh, they look sexier because laughter is connected to their ability to take care of their offspring

The adding machine by Elmer Rice Essay Example | Topics and Well Written Essays - 500 words

The adding machine by Elmer Rice - Essay Example Most importantly, being Mr. Zero is also associated with being oblivious to some serious life aspects. Mr. Zero seems to pay no attention to his needs, desires, and wants in life (Gabrielle and Sprinchorn 307). In other words, he observes a lifestyle that is notably characterized by zero personal concerns. He takes no action to develop personally and professionally, amid serious changes that are being realized around him. For example, the emergence of the adding machine is not instantaneous. However, Mr. Zero takes no effort to maneuver the situation. Conscious awareness on needs, desires, and wants would be expected for Mr. Zero, but unfortunately this is not forthcoming. Mr.1, 2, 3†¦is associated with being responsive to what is happening around an individual. Most importantly, it means taking charge and responsibility when the need arises. Here, dormancy is outweighed and outperformed by being active. Mr.1, 2, 3 has nothing to do with obliviousness. Essentially, there are actions, choices, and alternatives as far as Mr.1, 2, 3 are concerned. Killing the boss did not solve the issue between Mr. Zero, the boss, and the adding machine. If anything, Mr. Zero commits a crime for which he is tried, found guilty, and subsequently executed. In the context of being Mr. Zero, there does not seem to be any choice for his actions. The man is oblivious to his life and he, therefore, lives the outcome of whatever he does. Given that he is an accountant professional, though zero in nature, he is responsible for himself and who he is. The Elysian Fields mark a transition in Mr. Zero’s life. Mr. Zero’s execution marked his death, but the Elysian Fields bring him back when he is said to have woken up in a heaven-like setting (Gabrielle and Sprinchorn 329). Mr. Zero killed his boss over an adding machine that was set to replace him at the company. In Elysian Fields he wakes up to operate the machine, implying that his role had relatively changed. The Elysian

Niels Bohr Father Of Quantum Physics Philosophy Essay

Niels Bohr Father Of Quantum Physics Philosophy Essay Niels Henrik David Bohr was a Danish physicist born in Copenhagen on October 7th 1885. His father, Christian Bohr, was a college professor at Copenhagen University. Bohr had one younger brother named Harald, who was a mathematician, and a sister named Jennifer (Niels bohr, 1992). Bohr married Margrethe Norlund in 1912 and had six children. Unfortunately two were lost, but the remaining four would become very successful like their father. Aage followed in his fathers footsteps as a physicist, receiving the Nobel peace prize in 1975 for his collective model of the nucleus. His other sons would become a chemist, lawyer and physician (the bohr model). Bohr began his education at Gammelholm Grammar School in 1903, later entering Copenhagen University where he received his masters in physics in 1909. Soon after, in 1911, he received his doctorate. His doctors disputation was a theoretical work on the explanation of the properties of the metals with the aid of electron theory. It remains a classic to this day. The same year he received his doctorate, Bohr traveled to Cambridge where he studied under JJ Thompson. Unfortunately, they did not get along, so in 1912 he traveled to Manchester to study under Earnest Rutherford. It was here that he completed a theoretical work on the absorption of alpha rays that was published in Philosophical Magazine in 1913. Working off some of Rutherfords discoveries about the atomic nucleus, Bohr was able to develop a working model of the atom (Niels bohr, 1992). Perhaps Bohrs most important work was that with the model of the atom. Bohrs model, sometimes referred to as the planetary model, was able to provide explanation for concepts that were previously indescribable. Working off Rutherfords previous work, Bohr was able to successfully explain the spectrum of the hydrogen atom. While Rutherfords model focused mainly on the nucleus, Bohr paid greater attention to electrons. The previous model of the atom stated an electron was an orbiting planet. The problem in this flawed model was that the electron, moving in a circular path, would be accelerating. Acceleration would create a change in magnetic field, which would in turn carry energy away from the nucleus. The electron would eventually slow and be captured by the nucleus. Bohrs model expanded upon Rutherfords and solved many flaws of the previous model (The Bohr model,). Bohr discovered that the atom consisted of a small, positive nucleus, with negatively charged electrons traveling around it due to the electrostatic force of coulombs law. (Matthews 2010). Bohr stated that electrons travel only in successively larger orbits. The outer orbits hold more electrons that the inner ones and its the outer orbits that determine the atoms chemical properties (Niels bohr, 1992). Although Bohrs model eliminated many problems of earlier renderings, it was not without its own flaws. Bohrs model violated the Heisenberg Uncertainty Principle because it states that electrons have both a known orbit and radius. It also made poor predictions about the spectra of larger atoms, did not predict the relative intensities of spectral lines, provided an incorrect value for the ground state orbital angular momentum, did not explain fine structures and hyperfine structures in spectral lines and did not explain the Zeeman effect (Bohr model of the atom,). The Zeeman Effect is the splitting of a spectral line by a magnetic field (Foley). Even with these problems, Bohrs model was still important for laying a foundation for future study. Erwin Schrodingers electron could model, made possible by quantum mechanics, and would come to outdate the Bohr model in the 1920s (Niels bohr, 2009). Along with his structural model of the atom, Bohr was able to explain how atoms emit radiation. He suggested that when an electron jumps from an outer orbit to an inner one, it will emit light. His research found the wavelength of the emitted light is the same as the photon that carries the energy difference between the two orbits. This showed that atoms can only absorb and emit at certain wavelengths. This theory was later expanded into quantum mechanics (Niels bohr,). In 1930 Bohr changed his focus to the constitution of atomic nuclei along with their transmutations and integrations. He found that a liquid droplet would give a very good picture of the nucleus. He developed the liquid droplet theory which helped clarify and provide understanding of the mechanics of nuclear fission and the splitting of the uranium atom. This theory would provide an important basis for future studies in this field by Hahn and Strassmann (Niels bohr, 1992). Bohr was well known for his concept of complementarily. It helped to clarify some of the problems that he found in quantum physics. The theory stated that wave and particle aspects of nature are complementary and cannot both be true at the same time (Niels bohr,). In other words something must have either wave or particle like properties, not both. The concept of complementarity stated that classical concepts such as space-time location and energy-momentum, which in classical physics were always combined into a single picture, cannot be so combined in quantum physics (Complementarity principle,). In certain situations, the use of one certain classical concept will exclude the use of another classical concept. Bohrs views on the Principle on Complementarity were represented in a number of different essays he wrote from 1933-1926 (Niels bohr, 1992). Bohr was equally famous for his correspondence principle, formulated in 1920(Niels bohr,). This principle states that the behavior of systems described by the theory of quantum mechanics reproduces classical physics in the limit of large quantum numbers (Parker, 1983). In simpler terms, this principle is the idea that a new theory should be able to reproduce the results of older theories in the domains where those older theories work (Apply quantum principle, 1999). During the Nazi occupation of Denmark, Bohr being half Jewish, fled the country to escape persecution. He and his family left the country by fishing boat and went to Sweden. Bohr then traveled to England to discuss the invention of the atomic bomb. In 1943 he traveled to Los Alamos New Mexico to work on the Manhattan Project. He, along with other scientists, helped to develop the first atomic bomb. Because it had such a potential to cause catastrophic damage, Bohr viewed the bomb as a device that could unify nations. When the war was over, Bohr returned to Copenhagen and promoted the peaceful use of atomic weapons and energy. Niels bohr, 1992). Bohr gave back to the community by sharing his knowledge. In 1913 he held a lectureship in physics at Copenhagen University and did the same in 1914-1916 at Victoria University in Manchester. He was a professor of theoretical physics at Copenhagen University and from 1920 until his death; he was the head of the Institute of Theoretical Physics. Along with educating future scientists, Bohr was President of the Royal Danish Academy of Sciences and the Danish Cancer Committee, Chairman of the Danish Atomic Energy Commission and a member of the Royal Society and the Royal Institution (Niels bohr, 1992). Throughout his lifetime, Bohr received many different awards for his work in a variety of disciplines. The most prestigious being the Nobel Peace Prize in 1922 for his work on the atomic model. He also received the Hughes Medal in 1921, Matteucci Medal in 1923, Copley Medal in 1938, United States Atoms for Peace Award 1957 and the Sonning Prize 1961(Niels bohr,). Bohr had many other honors apart from theses medal and trophies. The institute of physics in Copenhagen was renamed the Niels Bohr Institute in his honor. On November 21st 1963 in Demark, the Bohr model semi centennial postage stamp was commemorated featuring Bohr, the hydrogen atom, and his formula for determining the difference in any two hydrogen energy levels. The atomic elements Bohrium and Hafnium were named for him along with asteroid 3948 Bohr. Towards the end of his life, Bohr began to show an interest in molecular biology. His final work, Light and Life, proposed an idea that life might not be reducible to atomic physics. It was unfinished and published after his death (Niels bohr,). Bohr passed away in Copenhagen on November 18th 1962 due to a stroke (Niels bohr, 1992). His work had an enormous impact on the scientific world of both his time and today. His extreme strides in developing the model of the atom led to the creation of an accurate model necessary for study in modern physics. His numerous formulas solved many existing problems and would lay the groundwork for future studies. If it were not for Bohrs passion and dedication to science many modern concepts would not exist today.

Teaching Argument Evaluation in An Introductory Philosophy Course Essay

Teaching Argument Evaluation in An Introductory Philosophy Course ABSTRACT: One of the greatest challenges in teaching an introductory philosophy course is convincing students that there are, indeed, reliable standards for the evaluation of arguments. Too often introductory students criticize an argument simply by contesting the truth of one of its claims. And far too often, the only claim in an argument that meets serious objections is its conclusion. For many students, the idea that an argument displays a structure which can be evaluated on its own terms is not very difficult to grasp. Unfortunately, the idea is grasped only in an abstract way, with insufficient appreciation of how structural problems manifest themselves in concrete arguments, and without the vocabulary for formulating structural criticisms. But this paper is not simply about teaching logic, it is about pedagogy. Our task is to instill in the student the habit of clear thinking. When we send our students out into the world, we have to ensure that they are prepared for it. Introduction One of the greatest challenges in teaching an introductory philosophy course is convincing students that there are, indeed, reliable standards for the evaluation of arguments.

Assignments: Several chain syllogisms. Session 6 This session should be devoted to the examination of the limitations of term logic. It has proved useful to consider simple arguments that make use of very basic truth-functional logic (modus ponens, modus tollens, and the hypothetical syllogism are easily enough explained). While these can usually be translated without too much effort into the form of a categorical syllogism, the awkwardness of doing so is clearly prohibitive. At this point, however, the battle is already won. The students are actively engaged in the logical analysis and evaluation of arguments.

Geronimo, Apache: A Defined Leader Essay

Geronimo, or Goyathlay, was a great leader from the Native American Bendokohe Apache tribe. Although Geronimo was not a chief, the tribe depended on the wisdom of his position as medicine man. Geronimo gathered such influence that he led the last force to formally capitulate to the United States by upholding the core Apache values that embody aspects that define a leader: aggressiveness, diligence, and courage. Geronimo displayed the core values of the Apache tribe, that of courage, diligence, and aggressiveness. These core values were what kept them relatively safe from the increasing white settlement of the west, including Arizona and New Mexico (theinitialjourney.com.) Aggressiveness, or assertiveness, and diligence are key aspects of a leader. A leader must be assertive as well as persistent in order to maintain a certain level of self-confidence and influence over those who are being led, even in the face of adversity. Geronimo was a great example of an assertive leader. Geronimo led the last major Native American Fighting force to surrender to the United States; thus having the longest resistance period. Upon the discovery that his mother, wife, and his three young children had been murdered by Spanish troops, he vowed to avenge his family by retaliating against as many Mexican settlements as possible. It was not until this time that he received his ‘power’ of seeing visi ons (Indigenouspeople.net.) It was because Geronimo held out the fight for so long, that he became the most famous Apache of all. By asserting himself and applying himself in order to uphold his values of family and justice, Geronimo became an essential force as medicine man, acting in and out of combat as a spiritual and intellectual leader of the people (not a chief.) He escaped from a reservation three times, the final time bringing thirty five warriors and one hundred nine women and children into freedom. It was through these acts that Geronimo transcended above and beyond advisor. Geronimo became an icon of freedom and persistence in the face of difficulty (indiginouspeople.net.) Through assertiveness and diligence, Geronimo led his people towards their goal of freedom, also exhibiting another leadership trait: courage. Geronimo was exceptionally courageous in the face of difficulty. After vowing to avenge his family and tribe after their murder was an extreme test of character and will. It was a desire for freedom that continued his ability to evade capture. â€Å"Geronimo, the most legendary Apache war leader, along with seventeen warriors, fourteen women, and six children had evaded capture despite pursuit by 5,000 U.S. troops, 3,000 Mexican soldiers, and numerous Indian scouts for more than six months. To the U.S. Army and the settlers in the area, the supremely resilient and determined Geronimo had personified the Apache problem and every raid on a village or wagon train was attributed to him. In the years following his surrender, Geronimo came to personify resilience in the face of overwhelming odds.† Tfaoi.com Geronimo became a legendary force against the involuntary capture of Native American Apaches. His courage against adversity compelled many to follow him. His statements of â€Å"coming from a land with no enclosures† inspired people to follow a dream of living simply as they once did; without white influence (indigenouspeople.net.) It was though this notion of courage to follow one’s true intuition in life. Geronimo was an exceptional leader, exuding leadership through the qualities of assertiveness, diligence, and courage. Geronimo led his people to freedom against white influence many a time over, evading capture the longest out of all Native American fighting forces. It was through diligence in repetition of effort, assertiveness of his character and moral intuition, and courage in the face of danger and difficulty that makes Geronimo a great leader.

The Concept of Earning One’s Citizenship Citizenship is defined as a being a citizen or a person owing allegiance to and entitled to the protection of a sovereign state. Citizen preferred for one owing allegiance to a state in which sovereign power is retained by the people and sharing in the political rights of those people. The concept of which in one of its earliest was given to us by the Romans, who had just began to understand the importance of a populace contributing to the decisions of its own fate. Modern American citizenship as we know it today was defined for us in the constitution of this nation by the founding fathers. Citizenship as they had envisioned it even back then was not free, but came with a price. A citizen was expected to carry out certain civic duties and responsibilities such as the defense of the republic, participating in state and local government, and voting on affairs of the nation as a whole.

Fruits to make a fruit battery Essay Example

Fruits to make a fruit battery Essay Example Fruits to make a fruit battery Paper Fruits to make a fruit battery Paper Magnesium, due to its reactivity, has a very high potential energy, so the electrons travel from it to the copper, which has a very low potential energy due to its unreactivity. The difference in the potential is called the cell potential difference. If the difference of potential energy is large, then clearly the voltage produced by the galvanic cell will also be large as voltage is potential difference. From the electrochemical series, magnesium has a standard electrode potential of -2. 37, and copper has one of +0. 34. The difference between the potentials is 2. 71, which is large, and therefore this will mean more electrons will be conducted creating a larger current, and also the difference between the potentials will also mean a higher voltage. If the anode was zinc (-0. 76) then the difference would be 1. 1 not as large a difference as the magnesium due to it being less reactive. Other examples could be zinc and magnesium, a difference of 1. 61, lead (-0. 13) and iron (0. 04), a difference of 17 and so on. This is how galvanic cells operate, storing chemical energy that is released as electrical energy when a conductor is connected between the two electrodes. This scientific theory supports my initial prediction that the magnesium and copper will produce the highest voltage due to their potential energy difference. Evaluation: I think that the experiment went quite well. It is hard to spot anomalous results on a bar graph, but I think my results are pretty accurate, and fit my prediction. However I feel accuracy was limited and could have been improved if a set of 3 results was taken, because I only took 2, it is possible that one result could have been wrong and changed the average, while accuracy is increased with three results. : There was not enough time to do this though. I think that the results gained using zinc and magnesium were more unreliable than the others, because there were big differences between the two results that were taken. For example, using lead and zinc the first time (in the grapefruit) a voltage of 0. 17 was produced, while the second reading was 0. 49V. This could be because we didnt change the metal strips after every fruit, meaning they had been reacting with both the air and the electrolyte/fruit. Accuracy could also have been lacked due to the difficulty in cutting out equal sized strips. We had to use a steel nail of similar surface area because iron foil was unavailable. Fruits are also very unpredictable and vary. I think that we should have perhaps focused on one fruit, like the lemon, and used three different lemons to increase accuracy. This would perhaps be a more useful approach. I believe further investigations are needed to help fulfill the aim of the experiment. I think that acids and alkaline solutions should be used instead of fruits due to their unreliability. This will make the experiment quicker too. The outcome would be more predictable. The distance between the two metals in the fruit could be varied in further work to again test the voltages produced using different combinations of magnesium, iron, zinc, lead and copper. You could start them with a centimetre difference between them, and then increase this by a cm until it reaches 5 cm. A variety of fruits could again be used as a variable in this method. Other variables to be tested are the surface area of the metals and how that would affect the voltage produced, as it clearly seemed to affect my results.

Self Reflective Course Concept Essay Example | Topics and Well Written Essays - 500 words

Self Reflective Course Concept - Essay Example A brief recap on the old concept of business that dictates the main essence of establishing a business is to maximize profits. These old concept discouraged organizations against social responsibility as the accountability of the social responsibility on the part of the organizational profit could not be viewed. It is on these basis that the new concept of business was entailed which necessitated that the business carries out its activities, becomes socially responsible and maintains its customers. This was a crucial aspect for various business ventures as most of them sustained the business venture with confidentiality and loyalty from their customers. The aspect of Social responsibility can never be over-emphasized in any organization. Sir Immanuel Kant a deontologist suggested that in order for people to act morally they must act from positions of duty. He also added that it is not the various action consequences that make them either right or wrong, but the intensions or rather motives of the person carrying them. Deontological ethics refers to the ethical normative stance that determines how moral an action on the adherence of the rule and finally rules. To the business organization morals are determined by what is generally right. Aspects of giving consumers the right product quantity, disclosing enough information about the various goods and services, giving quality products are all issues covered in deontological ethics. Teleological ethics touches on morality that dictates the moral obligations and duties and distinguishes it from what is desirable or good. Ethical egoism can generally be referred to as the position accorded to the agents of morals. Those at positions that necessitates their exercise of morals. These are determined by what is in their own self interest. Their relationship to business ethics is that they all contribute to the topic on ethics and guide the ethical profession Teleological ethics touches on
