Platos Repulic, book V Essay -- essays research papers fc

ABSTRACT: This paper discusses the viability of certain aspects (the sex lottery) of Plato's Republic, book V. It is college level 'A' paper. Book V of The Republic finds Socrates explaining the practical details necessary in the creation of an ideal polis. He proposes a system for population control and human eugenics based on a lottery of sorts which will determine who will mate with whom and when. The lottery is â€Å"rigged† by the rulers in order that the best of the â€Å"herd† will mate much more frequently than others. However, only the rulers of this society will know the lottery is rigged. This system will presumably assure that children will be conceived as the result of reason, not irrational behaviors such as love or lust, and will produce the best possible future generations (Plato 458d – 460c). I argue that Plato’s lottery would not have worked in his time, nor would it work now because the desire to propagate was and still is a human instinct propelled by passion, not something that can simply be reasoned away. While Plato proposed that licentiousness would be forbidden and matrimony given the highest degree of sanctity (458e), I do not think that would be enough to stop a massive rise in sex crimes and passionate affairs. Instead of a just society, Plato’s proposal would have created one of fear, self-doubt and lack of trust in the government and is not something I would advocate implementing. While we can never really know how this utopia would have â€Å"played out† in Plato’s time, the negative effects on a society when passions are forcibly controlled can be illustrated in a modern sense by the Catholic Church and our penal system. Plato wrote that guardians would be â€Å"drawn together by a necessity of their natures to have intercourse† (458d) and yet, their sexual interludes should be limited by the use of the lottery. It is important to point out that since reliable and accessible birth control is a recent luxury, Plato was not simply advocating for selective child birth, he was talking about abstaining from heterosexual sex unless you â€Å"won† the lottery. I don’t think Plato’s lottery system would have worked out as well as he envisioned. When the less desirable of the population were consistently â€Å"unlucky† and unable to propagate year after year, what would have happened to them psychologically? Given that copulation was to be an honor bestowed upon... ...or other punishments. Whether restraint of sexual instincts are willingly accepted or forced upon a community, the results can lead to a decidedly non-ideal situation. By looking at some modern examples, I have shown how human desire can, and often does, override reason and the law even when faced with community imposed consequences or dire punishments. While current society differs greatly from Plato’s Greece, people are still people and human instinct existed then just as it exists today. People who are denied the ability to choose if and with whom they can have sex are liable to become irrational or turn to violent means to reach that end, regardless of the era in which they live. In Plato’s ideal society these unsanctioned actions could have lead to an increased level in the public’s fear for their physical safety. Individuals consistently denied by the rulers to copulate might develop self-worth issues and finally, a pin-prick of imperfection in this utopian society may be discovered by those who are forbidden from enjoying physical relations with those they desire or love.

Speech on Happiness :: Happiness Essays

Today I am here to discuss a topic with you but I don’t know where to start. If I ask you, "Is Money a Prerequisite for Happiness?", how would you answer? Your answer should be NO. Definitely NO. But is this truly what you believe? Is this consistent with how you act? All of us want to make money to gain some status, some comfort and some luxurious. This money has brought; is bringing; and will bring so many differences between some of you and me. These differences will be later named as differences between the rich and the poor. If I ask you ‘Do you know what is happiness? You would thrillingly and pleasingly answer me YES, OF Course Then lets share some examples of the happiest man. One would experience happiness when a leads a luxurious life. One may also experience happiness when he had expanded his business almost across the globe. One may also experience happiness when he had his meal in the most famous and expensive hotel. One may also experience happiness when he attends honorable parties. One can’t imagine an ideal life like this. But don’t you feel I have missed out something in the above examples – yes, I have thereby missed out the actual meaning of happiness. No one can tell which philosopher in his writings has mentioned money to be as happiness. Which dictionary ever explains money to be a synonym of happiness? Which mathematician has ever given up a formula - LIFE + MONEY = HAPPINESS. None of the scientists ever brought up a formula – Money when given up at 100 degree Celsius gives you (Happiness)2 When none of us has ever come across such words and formulas, none of the great personalities has ever mentioned it, then who the hell has instilled it in our minds that money brings happiness. But among this debate one question still raises its head - What is happiness? Happiness is not actually leading a luxurious life but the luxury of living a life. Happiness is not actually about expanding your business, but it lies in expanding the horizons of life. Happiness is not having a meal in the most famous restaurant but to have it with your most beloved family. It does not lie in attending honorable parties but to attend a party with honor. Happiness is to wear a smile when it feels like crying.

Report on the Condition of Psychological Pressure of College Students

Title page Resisting Pressure: Survey on Chongqing University's Students' Psychological Pressure Group6 Supervisor: Wang Xu Chongqing University May 7, 2012 Abstract page Abstract This survey examined the condition of Chongqing university's students' psychological health. Our main aim is to find ways to deal with the pressure we students face. 100 Chongqing university's students were surveyed on both pressure they face and ways they use to deal with that. We predicted that academic pressure,emotional pressure and the pressure of employment can be huge to our students and it's hard for them to deal with that.Actually,pressure from the above three aspects was not that huge for our students,no matter they are science students or arts students,girls or boys. Also,it seems like that our students have their own set of ways to handle these pressure. Still,there are a certain number of students find they struggle to handle pressure from the three aspects,suggesting that Chongqing university 's students mainly stay a healthy psychological condition,but there are still things we can do to improve that. Body Resisting Pressure: Survey on Chongqing University's Students' Psychological PressureNowadays,with the rapid development of China's economy,psychological pressure more and more appear in newspaper,TV,or someone's life,especially,a university student's life. Many factors can be pressure for a university student. For example,academic grade point(GPA),emotional problems or job-hunting difficulties. After summarizing most pressure factors, we classified them to three aspects:academic pressure,emotional pressure and pressure of the employment. So,how the three pressure source affect university students and how the students deal with that?As to psychological sources of stress for college students, foreign research results are generally believed to include academic factors, social factors, life and economic factors, career factors. [i] For example, Misra's research shows tha t the Students' largest source of stress are factors that directly related to learning , such as test scores and test results, the burden of learning;The second largest source of pressure are social environment-related factors such as economic problems, lack of time to communicate with parents and friends. ii]The Armeli group's study shows that students's anxiety caused by the pressure of two aspects;on the one hand, it's high academic expectations that caused them anxious;on the other hand, it is the will of self-development and maintaining good interpersonal relationships contributes to that anxiety. [iii]Domestic scholars found that the pressure sense of college students mostly come from life events when thay are trying to adapt to college life. Severe psychological problems are caused especially by life events which are linked to their personal lives, their parents and family, learning progress , and most of them are negative events. iv]Li Lun and Wang Qian, according to whose r esearch,they pointed out that the psychological pressure of college students can be summarized into the three categories: pressure from family, work , learning problems ,love and interpersonal problems. [v]Li Hong and Mei JinRong's study indicates that college students' main pressure source including:study,job-hunting,interpersonal relationships,life problems,romance,economy,society,tests,family,life and study environment,future,competence,personal affairs(development,outlook,confidence),health,competitiveness. 5 categories in total. [vi] However,it's not hard to see that the studies which have been done mostly are qualitative analysis . Most researches focused on frequency and type of event that caused pressure,but lack the discovery of the psychological experience of degree research. Therefore, we want to use the college students' psychological pressure gauge as a theoretical basis to provide a scientific analysis of mental health status of college students so to put forward some constructive ideas for college students to stay psychological health. . Method ParticipantsParticipants included 100 Chongqing university students (56 females, 44males;61 majoring in science,19 majoring in arts),most of them are in their freshman year,the other are junior students. Materials Stress in college students is texted by 25 questions listed in each of 100 questionnaires. We tested it in three different aspects–academic pressure,emotional pressure and the pressure of employment. participants are requested to make multiple-choice or single choice so let us know the degree of their psychological pressure. Pressure degree is measured on the basis of Students pressure measure table. vii]And ways to handle pressure are concluded from these analysis . Procedure As our first step,we gave away 100 questionnaires ,then we collected the data and made an analysis of it using the Students Pressure Measure Table,at last,we put forward our view and suggestions. Note:M–male( 44); F–female(56);ST–science students(61);AT–arts students(39) Academic pressure group Emotional pressure group I. [pic] [pic] Unexpectedly,a significant difference between science students and arts students was found. However,there was no obvious difference between boys and girls was indicated.We deduced that the former phenomenon was due to the following reasons:For one thing,science students are busy doing their homework or experiments ,when compared with arts students,they have less time to experience loneness and their life maybe much simpler. This point of view was supported by Figure 2—Academic performance was more important for science students than arts students. As the saying goes:Simple is beautiful. Simple life lead to a higher happiness level. For another,it's a new trend which was observed by many sociologists that boys majoring in science are more appealing for girls than boys majoring in arts.Combining with the fact that Chongqing Universi ty's Male to Female ratio is 7 to 1. It's no surprise that boys majoring in science are less pressed by factors like romance but money is a problem. Also unexpectedly,we found that girls we surveyed put more attention the academic factors,Perhaps that's why girls feel more happy than boys–girlfriends' mood may always changing but your GPA is always there. Is that a reason why girls are always studying hard than boys in college? II. [pic] [pic] [pic] We predicted that girls are more easy to feel lonely and have a stronger urge of taking with others.Moreover,they might be more good at dealing with their psychological pressure. Our survey results partly support our idea:most girls are not always troubled with the feeling of loneliness and girls do know how to deal with own pressure—they write letters or diaries;they can cry out or go shopping with friends.. Unexpectedly,compared with boys,they are less likely to talk about their problems than boys. So,why? After looking t hrough our data collecting results,here is the reason:among the 54 girls we surveyed,39 are majoring in science.As we all know,in some science majors,girls are rare,say,The Civil Engineering,so it's no wonder they don't like to talk about it:female friends around them,especially in a same class are are. So,how about build a relationship with boys,treat them as their â€Å"girlfriends†? III. [pic] [pic] [pic] Unexpectedly,it seems like that most students who received our survey all have a familiar results according to the figure1,2,3. Half students will be pressed by others' views ,pressed by the mainstream definition of success,and pressed by dealing interpersonal relationships no matter he or she,science or arts.This phenomenon can be explained by the theory of Group Psychological Effects. ,which says because of the need of seeking belonging sense,individuals will obey the norms and standards of a certain group. However,Group Psychological Effects are not equivalent to each member,that's why the other choose an opposite choice. Also unexpectedly,girls are more pressured by â€Å"success† though we traditionally thought that boy was the one who shouldered too heavy an expectation. All in all,we found that students in Chongqing University generally stay in a healthy emotional pressure level,and the existence of there pressure sources might be a good thing.Because it can help college students mature both physically and mentally thus they will learn to understand others and get along well with themselves. We always believe that EQ is more important than IQ,so the pressure can increase their EQ,even stimulate them to rebuild a better self. Job-hunting pressure group Discussion The purpose of this study was to find how different levels of pressure college students bear and put forward constructive methods to deal with that.We predicted that a large number of college students are experiencing or have experienced different levels of depression caused by pressure. In this study,those students that we tested mostly showed healthy psychological condition and a good knowledge of ways to let out pressure. Thus,our hypothesis was not supported by this study. But,how and why? Is it true that college students are living happily and without pressure given by society. We postulate that this result can be explained by the following reasons:First of all,the concept of â€Å"vanity† may explain this unusual phenomenon.Fear of being other people see themselves vulnerable and the trend to pretend optimism as all people like optimistic make them choose some options which are not true. Secondly,our participants mainly are freshmen,in their first year in university,the impact of pressure from the three sources are small as everything is new which attract their most attention. Last but not least,it's maybe cultural background that affects our students choice. For example,most westerners are used to express theirs feelings directly,however,we Chinese are more familiar with words like†just so-so†,†not bad†,which are not clear to escribe our feelings. And that may make an effect on our survey. In conclusion, the results of this study provide some fascinating insights into the pressure level Chongqing University students feel. Contrary to what we predicted, most students may indeed always stay in a good psychological condition and know a lot to get alone with their emotion. This research and other research to follow will contribute to knowledge of the main condition of Chongqing University students and good ways to deal with pressure. —and possible advantages—of skipping meals.The mixed results of this study suggest that we have much more to learn about resisting pressure in college. ———————– [i] Rawson H E,Bloomer K,Kendall A.

Miracle on St David’s Day by Gillian Clarke Essay

Miracle on St David’s Day is an enchanting, and ultimately optimistic poem relating to the theme of identity by Gillian Clarke. The poem tells the story of a man in a mental institution, who exceeds the expectation of both the nurses and his fellow patients when he regains the ability to talk. In the first stanza of the poem, Gillian Clarke describes the country house in what seems to be an idyllic setting, â€Å"The sun treads the path among cedars and enormous oaks, it might be a country house, guests strolling†. However despite the seemingly pleasant tone, implied by the use of her making it seem informal, through the relaxed wondering of what the House may have been,† might be a country house, guests strolling†, suggesting normality her use of the word might alerts the reader that this idyllic setting may be an illusion and not what it first seems. The illusion of normality is swiftly extracted by the opening line of the second stanza, â€Å"I am reading poetry to the insane†. This line ends with a certain finality, that is so abrupt that it disturbs the so far, flowing effect to the poem, also implying informality and normality, to the effects that it shocks the reader, not only in the disrupted rhythm of the poem but also in the disturbingly blunt reality of what she is saying. Furthermore this is shocking because it is not commonplace for people to be reading poetry to the insane. Gillian Clarke does this numerous times during the poem in order to stop the reader, so that the poem does not ramble, and make it more interesting, â€Å"A beautiful chestnut-haired boy listens entirely absorbed. A schizophrenic†. This use of contrast between the descriptive lines of the opening stanza and the flat, and remarkably blunt, tones of this line introduce the reader to the contrast between the setting and the guests. As we can observe from the line following, â€Å"I am reading poetry to the insane†, which instantly restores the mood of the poem to informal with the humor, of the old woman who is constantly offering the narrator coal, when it is March and she would have no means of getting coal. By the use of having the woman saying humorous things, Gillian Clarke is also contrasting her with the other patients at the home, as she is the only one who is talking. The poem also uses poetic devises such as personification, â€Å"An afternoon yellow and open mouthed†. It uses metaphors, â€Å"In a cage of first march sun†, and similes such as, â€Å"Outside the daffodils are still as wax†, to make the poem more interesting to read, and also without these techniques the imagery of the poem, that the people in the home are daffodils would not be portrayed and the final message of the poem would not be presented to the reader. Thus the poem would be pointless. Gillian Clarke also uses enjambment in the poem, which disturbs the flow of the poem, and I think is also relating to the disturbed personalities of the patients in the home. Enjambment is effectively used in the third to fourth stanzas, as this is a rambling scene of the immense man struggling to get to his chair, and so Clarke reflects this in the appropriate use of enjambment between the stanzas. The first March sun is described as a cage in the third verse as it is sa ying that for these people who have no freedom, even their enjoyment of the sun is trapping them, and they have no choice but to be out absorbed in it. These poetic devices are also used to build up the character of the man in the poem. In the third stanza where the man is introduced, he is described as a big, mild man, and a laborer, who is being tenderly led. This use of contrasting language informs the reader that even though the man is large in size he has to be tenderly led like a child, continuing to imply to the reader that there is something wrong with him. This is confirmed in the forth verse where he is described as rocking, a common action by insane people as it comforts them. His description is also emphasized by the repetition of the words big, mild and dumb. These words make him seem even more immense, which is odd when they are combined with mild. When the huge laboring man speaks he is in beautiful surroundings reciting a poem about daffodils, which is not only being ironic but is breaking the stereotype of laborers being very masculine and rather insensitive, whereas here he is being portrayed as almost feminine and extremely sensitive. What strikes me most prominently when reading the poem is the amount of imagery used to bring emphasis to the overall meaning of Clarke’s poem and to make it more interesting. She has chosen the â€Å"Daffodils†, by W. Wordsworth, as the music that the mute man chooses to speak after forty years of silence. I believe that she has also chosen to describe the man who cannot speak as mute as it is also a musical term, and so therefore is not just emphasizing that there is no speech in his life, but also that there is no music, relating with happiness and merriment, and therefore is saying that without speech there is no joy in the laborer’s life. However when the rhythm of the poetry he is read awakens him, it appears to turn apparent life into reality. The poem is a possible way to show his waking from a world of misery to a reality of nature’s beauty and rhythm, â€Å"Since the dumbness of misery fell he has remembered there was a music of speech and that once he had something to say.† This is also playing on the word dumbness, as dumbness aside from meaning stupidity also is relating to the man who cannot speak as a person who is mute can also be described as, â€Å"dumb†. Informing us that the poem is saying that music is good, as when he cannot speak, and there is no music, it is described as, â€Å"misery† and when this, â€Å"falls†, and he has remembered that there is something to say a thrush sings, representing happiness, and the once, â€Å"wax† still daffodils are flame, representing excitement, life and activity. Therefore Gillian Clarke is saying that the man was not properly alive until the music in his life was restored. He is reciting poetry because what he has heard from the nurses in the institution has restored his memory and he has remembered a poem that he had learnt as a child at school. We know this because Clarke informs us in verse thirty-one, â€Å"Forty years ago, in a Valleys school, the class recited poetry by rote†. I believe that Gillian Clarke’s poem is also relating to music through this imagery. â€Å"Since the dumbness of misery fell he has remembered there was a music of speech and that once he had something to say.† When he speaks there is an immediate exchange of characteristics, the once lifeless patients are alert and the nurses are frozen as the patients once were. I also notice that in Clarke’s poem the daffodils seem to represent the people at the home. At the start of the poem the daffodils are â€Å"open mouthed† showing the way that the patients don’t react to the poetry, as this is the face that people use when they are bored and not listening. Their open mouths show how unreceptive the patients are, once again removing any sense of normality as Gillian Clarke alienates them from ordinary sane people. When the miracle of the man speaking occurs the flowers are silent and still, showing that far from the boredom and lack of interest displayed before, everyone is amazed. We can deduct that the daffodils are not merely flowers, by the use of lines such as, â€Å"their syllables unspoken†, as obviously, flowers can speak no syllables. I think that the use of the candle related words throughout the poem are deliberate, when the flowers are as still as, â€Å"wax†, the man is not speaking and when he does they are a flame, which is representing that the man’s hope, which has always been there, the wax, but when he speaks it is â€Å"a flame†. It is alive. I think that the, â€Å"first bird of the year in the breaking darkness† is symbolic as the first bird of the year, is representing the first speech in the mans life for many years, and the darkness which is now breaking is the bad times of when he could not speak. His first words in many years are described as a bird, as this also relates to the theme of music. Gillian Clarke effectively alienates the patients in the home and portrays the fact that although they are physically there, they mentally are not by the constant use of word absent, â€Å"I read to their presences, their absences†. St David’s Day by Gillian Clarke illustrates the theme of identity through the use of including people in a mental institution, as they have no identity. Yet after forty years a man’s identity breaks through. I believe that this poem is trying to communicate the fact that everyone has an identity; no matter how masked it is from the rest of the world, and by the use of describing them with flowers that cannot speak (which have inner beauty, she is saying that everyone has some kind of identity and beauty. Emotion plays an important part in the poem humor, misery and shock are shown to us and this makes the poems more realistic. Ultimately I feel the reason this is a very effective poem is that the use of daffodils and Wordsworth is subtle but carries a significant meaning that is backed up by the tone of the rest of the poem. I find that the poem is truly touching and although the main message of the poem is quite discrete, the way that it is portrayed makes it seem that you, the reader are really experiencing the miracle.

Bromination of Acetanilide

The objective of this experiment was to use melting point and NMR to determine which of two isomers, ortho or para, would most likely form after brominating Acetanilide through electrophilic aromatic substitution. Procedure/Observations: 1. Weigh out ~280 mg of acetanilide in a 10 mL r. b. flask with a stir bar. 2. Then, add 2. 0 mL of glacial acetic acid using a calibrated Pasteur pipet. 3. Stir the mixture until all of the acetanilide has dissolved. It may be necessary to add more acetic acid dropwise until full dissolution has occured. In the fume hood, add 0. 6 mL of 4. 1 M bromine solution in acetic acid. 5. Cap the round bottom flask before returning to the bench. 6. For 15-20 minutes, stir the reaction mixture at room temperature so that the reddish-orange coloration will fade and a solid precipitate will form. 7. Return to the hood and add a few more drops of the bromine solution in the hood if all the coloration fades. 8. Once the reaction is complete, return to the hood. 9. Transfer the mixture to a 25 mL Erlenmeyer flask with 10 mL of water. 10. Rinse the reaction flask out using another 5. 0 mL of water. 11. Using a Pasteur pipet, add 30% sodium thiosulfate dropwise while swirling until the bromine coloration is no longer visible. 12. Return to the bench to complete the final work-up. 13. Cool the reacting mixture in an ice bath. 14. Collect the solid precipitate using a Hirsch funnel through vacuum filtration. 15. Wash with ice cold water to complete the transfer. If the crude product is yellow, disconnect the vacuum, add a few drops of the sodium thiosulfate solution, then reconnect the vacuum. Follow with 1 or 2 washings of ice cold water. 17. Dry the crude product 5-10 minutes using the vacuum. 18. Recrystallize the crude product using an ethanol/water mixed solvent combination. Be sure to dissolve the crude product in the minimal volume of hot ethanol with swirling. 19. Add water dropwise until a cloud point is reached. 20. Rewarm the solution until it is clear again. 21. Allow the solution to cool until crystals form before icing. 22. On a Hirsch funnel under vacuum using cold water washings collect the crystals. Continue the vacuum for 5-10 minutes to dry. 8. Find the final weight and calculate the yield. 9. Find the melting point of the product, then obtain the 1H NMR of the product in CDCl3.

Sequence Diagram Flight Reservation System Assignment

Sequence Diagram Flight Reservation System - Assignment Example The sequence diagram is a critical part utilized in procedures of analysis and design documentation of user requirements. The sequence diagram is a tool of Unified Modelling Language (UML) that represents the interaction of different actors with the system in order to get a result/response (Bell, 2004). The Sequence diagram is one of the most usable and useful diagrams to represent the interaction of one or more objects’ interactions with one or more systems. It is pertinent to mention here that we have to develop / draw a Sequence diagram for each and every Use Case. The Sequence diagrams are used to model the usage scenario of the system, the logic of the methods and logic of the service. The sequence diagrams are used to describe the complicated operations, methods or functions in graphical or pictorial mode. Moreover, it also represents the services provided by the system to their clients, for example, the web services i-e online flight reservation system. The Use Case dia gram enables modelling of a business view of the scenario, the Sequence diagram contains implementation details of the scenario, including the objects and classes that are used to implement the scenario, and messages passed between the objects (Ambler, 2012). As per the sequence diagram (given below) of the online Flight Reservation System and the definition of the sequence diagram, the actors that were identified in Use Case Diagram (customer, website) has been utilized in the Sequence Diagram. The first actor is the 'Customer' that would interact with the 'Website' (system). As shown in the following figure, the customer does all the interaction with the system from searching flight till the provision of the PIN code. Initially, the customer opens the website of the service provider (airline or agent of the flight reservation) and clicks the search flight tab of the website. The website would open the flight search form and the customer has to enter the required information includ es: the departure and arrival airport, one way or round trip, the date of departure and return (if round trip) and the number seats / tickets. The customer submits the form and after processing, the website shows the search results. At this point the customer can go back to the search page and re-enter all the information, otherwise, the customer can select and book the flight. The website provides the review page along with payment information. The customer has to fill the form with required information include: full name, passport number and payment method (credit card information). The website provides the confirmation page and the customer confirms the booking. The system processes the customer’s request and presents a personal identification code (PIN) for the future reference (Popkin Software, 1998). Sequence Diagram Reference List Janssen, C., 2010.

Corporate Tax Policy between USA and Ireland Article

Corporate Tax Policy between USA and Ireland - Article Example The policies also vary from country to country, as they are formed to suite the existing environment. Therefore, this manuscript will compare the tax policies of USA and Ireland using the opinions of various scholars. In the article by Sinn, the author suggests that corporate tax policy in Ireland is more effective in creating jobs and tax revenue than United States. He mentions Ireland as one of the European nations that have improved their corporate tax collection through alterations in the Irish tax Code. The author further explains the different techniques applied by most European countries in corporate tax collection to generate revenue and create more jobs. For instance, the use of proportional taxes called ‘flat taxes’ are utilized to attract foreign investors. In addition, the earnings retained in the corporate sector are not taxed while those on distributions are. The article continues to applaud the corporate tax policy system of Ireland as a source of tax reve nue with a potential of creating numerous job opportunities than the US. In other words, Sinn maintains that with increased foreign investment because of friendly taxation policies, revenue is increased which in turn generates jobs (Steinmo, 1989). The author also proposes two defensive mechanisms that can help in tax collection including the corporate tax especially in European countries. For instance, Sinn talks about tax harmonization such as that of indirect taxes to the import country and de-taxation of the income earned through corporate profits. This, he argues will boost the revenue collection in Ireland, which is transformed into job opportunities across the country. It is also significant to note the observation by the author concerning tax harmonization in the corporate world and other sectors of the economy in return for an increase in Gross Domestic Product (GDP).

As a result, the government jumped in the advancement of the economy because of the new revenue resources such as corporate organizations and other sectors. The writer explains that this was not possible during the old days hence such a move attracted many policy makers and other stakeholders. Sven further analyses the politics involved in the tax policy system of the United States especi ally during the 1980s. This article puts emphasis on the Tax Reform Act that swept America in 1986 (TRA ’86). The author describes how the influence of this historic Act under the presidency of Ronald Reagan influenced other states around the world in the implantation of their tax reforms. Such tax reforms led to improved corporate tax policy systems in Europe especially in Ireland. This helped generate revenue and create job opportunities for their citizens. The author further points that, the integration of corporate taxes, and progressive income had several influences on the proceeding taxation developments. This led to the transformation of many nations into modern states because of increased
