Plato Republic Essay Example For Students

Plato Republic Essay In the last book, Book X, Plato criticizes poetry and the fine arts. Plato feels that art is merely the imitation of the imitation of reality, and that poetry corrupts the soul. Socrates says that artists merely create things. As an example, if a painter draws a couch on his canvas, he is creating a couch. But the couch he creates is not the real couch, it is nothing but a copy of an ordinary, physical couch which was created by a craftsman. But the ordinary, physical couch is nothing more than an imperfect copy, or image of the Form of Couch. So, the couch on the canvas is nothing but a copy of a copy of the real couch and is therefore three times removed from reality. Socrates then goes on to explain that an artists knowledge is also third-rate. If an artist is painting a picture of a table, for example, he is copying a table that has been manufactured by a furniture-maker, and this furniture-maker has more knowledge of the table than the painter does. But there is someone who has ever more knowledge about the table, the person who wants to have the table made. He is the one who gives the furniture-maker instructions to follow when making the table, according to its purpose for the buyer. So, the buyer of the table knows more about the table than the furniture-maker, and the furniture-maker knows more about the table than the painter. Socrates believes that only philosophers have the first-hand knowledge of things, since they believe in The Forms. Socrates also denounces Homer. Socrates feels that in his writing, Homer has pretended to be people he is not, such as a politician, general, businessman, teacher, and philosopher. Socrates feels this is wrong because Homer is claiming to be able to perform these functions that he has written about, but never really performed himself. He feels that Homer is abandoning reality. Plato feels that poetry has no place in his Ideal State, and should be banished until it can show itself to be a friend of philosophy. In conclusion, The Republic was Platos ways of expressing his Theory of Forms. The Forms played an important part in Platos Ideal State. However, Materialism does not believe in Platos Theory of Forms. A Materialist would disagree with many of the things that Plato talked of in The Republic. The main idea behind Plato Theory of Forms is that the Forms are not physical objects, but instead are only known through the mind (reason). The Forms are not known through the senses. They exist in a realm beyond physical reality. As in the example with beauty, it is ultimately an idea, not an object. One must understand what true beauty is before they can judge a particular object to be beautiful or not. The Forms are different from physical objects in that they are eternal and universal. Even the atoms that Materialists believe make up objects are not eternal. Also, if the ideal objects are the objects of knowledge and intellect, then what do Materialists believe knowledge is based on? Obviously it would be something based on the physical world. According to philosophers, knowledge of The Forms is required to have true knowledge. Then philosophers must feel that Materialists do not have true knowledge. Materialists believe that reality only consists of matter, however, philosophers believe that these physical objects are only real in a secondary sense, and that these objects are only imperfect copies of The Forms. Materialists also do not believe in spirits, souls, and gods and therefore would not understand Platos belief that life was to involve a movement upward toward the Forms, as this was a movement of the Soul.

Free Essays on Partial Birth Abortion

Partial Birth Abortions: Recent Developments Abortion is a topic that many people feel very strongly about, whether for or against it. Since the topic came to precedence in the early 70’s with the case of Roe v. Wade, many people have polarized to one side or another. Political parties are also among this polarization; their agendas for this topic are very different. Recent developments have brought new life to a topic that hasn’t much changed since the Supreme Courts landmark decision. The recent developments are in response to the process of the term ‘partial birth abortion’, which has become one of the great political deadlocks of our day. The history of abortion is one that stretches back to the time of Egyptians. It is however not until the early 1970’s that the issue of abortion came to be in the hearts and minds of the average citizen. Roe v. Wade legalized abortions and brought the topic to the attention of everyone. In the 30 years since the legalization of abortions for the first two trimesters there have been over 40 million abortions, whether or not we are better off for these abortions will never be known.

Hysteria of Salem witch trial in comparison to the 1980s day care case Term Paper

Hysteria of Salem witch trial in comparison to the 1980s day care case hysteria, - Term Paper Example Peasants used witchcraft to invoke charms for agriculture and farming, which gradually transformed from white magic into dark magic with a growing association with evil spirits and demons. With an increasing association of superstitions with the devil, incidents of witchcraft persecutions also increased rapidly, causing panic that led to aggressive witch hunts (Adams 69). On the other hand, the daycare sex abuse hysteria of the 1980s was in the form of panic that featured claims of child abuse, specifically sexual abuse, and satanic ritual abuse against providers of daycare (Malloy, Lyon & Quas 164). As more mothers ventured into employment and had to be away from home, a large number of daycare centers opened up to care for their children. However, an outstanding case in California’s Kern County started a wave of panic, lasting for nearly a decade. Characterized by incredible accusations of children being sexually molested, the panic spread out of the United States to New Zea land, Canada and some countries in Europe (Malloy, Lyon & Quas 164). The most prominent cases in the United States were Kern County child abuse cases; McMartin preschool trial; Fells Acre Day Care Center; Wee Care Nursery School; Cleveland child abuse scandal; and Little Rascals Day Care Center (Malloy, Lyon & Quas 165). ... The two sets of trials originated from the behaviors of children and the statements they issued. Driven by hysteria, parents and doctors interpreted the statements and behaviors in extremely portentous and threatening ways, rather than innocent and rational interpretations. It is the panic that led the people to believe the remotely conceivable accusations placed by children, ignoring all the inconsistencies as narrated by either scared, confused or preconditioned children. In both sets, literature analyses show that the prosecutors were asking leading questions. Repetitive questioning led to multiplication of the accusations and with the heightened spread of the hysteria, there were new targets of the accusations. Most of them were those that defended the accused or showed cynicism about the charges. The hysteria and bias against the accused in both sets of trials led the prosecutors and investigators to find meaning in very unlikely places. For example, in the Salem trials, the inv estigators concluded that a mole on an accused person’s body was an entry or sucking point for evil spirits and demons. On the other hand, it was concluded that drawing hands by children on stick figures was evidence of them having been molested in the daycare cases. Another unlikely conclusion in the daycare cases drawn was that the hatred of tuna fish by a child was caused by exposure to vaginal odor (Malloy, Lyon & Quas 162). The insistence and use of leading questions by the investigators rendered the investigations themselves as the roots of multiple problems. Effectively, the accused were faced with the burden of proving their own innocence in both sets of trials. For example, in the Salem trials, the

Does Inernational Trade hurt the Economy Essay Example | Topics and Well Written Essays - 500 words

Does Inernational Trade hurt the Economy - Essay Example Opponents and supporters have raised their opinions in numerous election campaigns, interviews and journals. In essence, various studies have been carried out to identify the problems and benefits that accrue from international trade. Japan is one of the countries that have been affected either negatively or positively by this trade. This is because of its diversified trade that depends mainly on trade in the international market. Countries benefit when they trade. When these countries produce different product, they benefit to a greater degree. For the past decade, Japan has benefitted immensely from its interaction with other in the international market. In reference to a study conducted by Flaherty (1999), international trade improves a country’s technology and improves the productivity levels in turn. This has been the case with Japan which has seen the level of technology improve due to raw materials from trade partners and available market for the finished goods in other countries. Flaherty (1999) asserts that the employment available becomes efficient and average incomes increase and the levels of standards of living improve. Statistics indicate that since Japan involved itself with international trade the living conditions for the local citizens have improved tremendously. In addition, since the elimination of the trade barriers as a result of globalization, Japan has witnessed a decrease in in flation and unemployment rates. Needless to say, international trade has caused a decrease in prices of commodities and increased product quality and choice. Increased International trade has triggered an increase in Japan Products. Japan exports of goods and services have highly generated income. For many years, the country had experienced deficits in its trade balance. Increased International trade has reduced the deficit that has been contributed by higher imports and low exports. This has
