Free Essays on Platos Republic

There are three questions that must be answered when talking about the tyrant that is described in Plato’s â€Å"Republic†. First you must explain the character present in the tyrant. Second you must describe the kind of life that a tyrant can be expected to live. The third and final question is why is the philosopher’s life a better life than that of the tyrant. What is the character of a tyrant? This is a question that Socrates answers very decisively. He says: â€Å"namely, that he is inevitably envious, untrust- worthy, unjust, friendless, impious, host and nurse to every kind of vice, and that his ruling makes him even more so. And because of all these, he is extremely unfortunate and goes on to make those near him like himself.†(580a.) Pretty much Socrates just describes the man that no one wants to be ruled by. A tyrant that rules is a man who scares the people he rules because he is a man with no conscious, and that is frightening when the person has so much power. The next question that must be answered is: What kind of life can a tyrant be expected to live? A tyrannical man can be expected to live one of two lives at any point in time. He can be a tyrant who is one of ruled or he can be a tyrant who is a ruler. If he is a type of one that is ruled, he is a man who will probably live his life committing petty crimes and offenses. He will: â€Å"steal, break into houses, snatch purses, steal clothes, rob temples, and sell people into slavery ¼Ã¢â‚¬ (575c) In this type of man’s private life, he is one: â€Å"who associates primarily with flatterers who are ready to obey him in everything. Or if he himself happens to need anything ¼ isn’t he willing to fawn on them and make every gesture of friend-ship, as if he were dealing with his own family.†(576a) So someone of a tyrannical nature is always: â€Å"a master to one manor a slave to another and never gets a taste of either freedom or true friendship.†(576... Free Essays on Plato's Republic Free Essays on Plato's Republic In Plato’s Republic, Socrates, Glaucon, and Adeimantus build and imaginary city. When deciding how to implement this city they realize that they must start with the children. They discuss how the children should be educated through muses, or music, and gymnastics. This leads them to discuss musicians and painters. Socrates discusses a theory of forms which states that the physical aspect of something is a particular, like human beings. But, what it is to be something is its form. In Book X of the Republic, Socrates said, â€Å"the painter, we say, will paint for us a shoemaker, a carpenter, and other craftsmen, although he doesn’t understand the arts of any one of them† (598c). Socrates claims that painters have no understanding of the form or what it is to be a good shoemaker. The ontological criticism of this would be that all painters do is create an image that is three times removed from the form. When a painter paints an object he paints the particular, or what he sees. The epistemological criticism of Socrates’ statement is that image-makers tend to not know the form. For example if a painter were to paint a shoemaker performing his craft of shoemaking he may capture a shoemaker who isn’t very good at his craft or paint a step not need in the shoemaking process. But, in Book V Socrates suggests that it may be possible for an image-maker to create an image close to the true form. He said, â€Å"Do you suppose a painter is any less good who draws a pattern of what the fairest human being would believe and renders everything in the picture adequately, but can’t prove that it’s also possible that such a man come into being†(472d). This suggests that it may be possible for a painter to paint almost perfect forms. If a painter were to paint a man more beautiful than he actually was then he would have painted the man closer to the form of beauty. He would have erased any imperfections of the particular and ... Free Essays on Plato's Republic Plato’s Republic Philosophers, economists, and novelists have written on the subject of the â€Å"perfect society† since the beginning of time. Theories vary greatly, yet some are surprisingly similar. During the late fifth century B.C.E., one of the most influential writers in Western society was Plato, an Athenian philosopher and teacher. Many aspects of modern Totalitarianism and Egalitarianism can clearly be seen in Plato’s Republic. â€Å" If woman are to have the same duties as men, they must have the same nurture and education;† in this manner Plato promotes equal education for all members of a nation, in order to achieve maximum productivity from society. Plato discusses the importance of equality of the sexes and specialized education to the stability and prosperity of the civilization in his dialogue. During Plato’s time, sexual equality in Athens, as well as equality in general, was an unthinkable concept. Men were thought to be superior in most tasks and were treated appropriately by society. â€Å"Full citizenship in Greece was normally confined to adult male landowners,† which excluded a large portion of society that consisted of women, plebs, (common people), slaves and those men who were free but did not own any land. Plato argued for the equality of the sexes on the basis of everyone’s unique contribution to society. â€Å"Are dogs divided into hes and shes, or do they both share equally in hunting.† Plato observes the superior physical ability and endurance of men, which separates the two different sexes. Women’s duties were confined to the house and the nursing of offspring, while the men carried out all other duties. Plato goes on to say that, â€Å"Men and women alike posses the qualities which make a guardian; they differ only in their comparative strength or weakness.† He also points out that not every aspect of society is centered on physical strength and endurance. Asserting that the gifts... Free Essays on Plato's Republic There are three questions that must be answered when talking about the tyrant that is described in Plato’s â€Å"Republic†.

Originality or Comformity essays

Originality or Comformity essays Many people use clothes to communicate thoughts, feelings and expressions. If school uniforms were mandated, this form of expression would be stifled. For most students, uniforms would be a drudgery to wear. First of all, uniqueness would be hard to show amongst the students. If everyone looked the same, how could anyone be an individualist? We d start to become; and eventually be, conformists. In the same way that originality is lost, part of our personal freedom is infringed, by making students wear uniforms. Students use clothing to express opinions, and students have a right to an opinion, dont they? The charter of rights and freedoms states that, every person is entitled to the freedom of choice. If students are forced to wear a uniform, and robbed of their freedom of choice, then several statements from the charter of rights and freedoms, would be made untrue. If a students clothing is dictated to them, it halts their liberty of choice and expression. Another consideration of uniforms is that they must be cleaned constantly. To maintain a consistent personal hygiene, uniforms would have to be cleaned at a constant rate. Rem ember, there is a limited amount of uniforms per student, so students cant wear a different set (of uniforms) everyday. Also, today, no service comes without a charge. Thus cleaning the uniforms regularly would cost money. Some uniforms even need to be dry- cleaned. Through the eyes of a teenager, expression of thoughts and ideas is one of the most important forms of communication, and uniforms would make this almost impossible. Clothing is a legitimate way for many people to express themselves as human beings. ...

Communication is very powerful and wonderfully shown through the voice of slaves. The culture of the African American who has experienced such slavery is full of much hurt and pride. The listener can understand the hurt and frustration that these slaves had to experience. A sense of pride is also noticed because the African Americans seem to be proud that they have come such a long way. The language used by the slaves is the English Language. Although the language is English, the slaves have a slang that is used and makes it hard to make out at times. The language is perceived to be broken English. After reviewing some of the voices and the folklore songs it was important to develop recognition of the way the African American culture speaks and refers to things. This deciphering of language is used by many without recognition that one is even doing it. Language is wh at allows the listener to comprehend what is being projected by the African Americans. â€Å"Language is the primary means people use to communicate with one another† (Words and Meaning). This form of language through music such as folklore is common in many cultures. The folklore music presented by the African American slaves is like a story told in a different language.

The Norton Anthology Sylvia Plath Essay Example for Free

The Norton Anthology Sylvia Plath Essay Imagery is the essence of all forms of poetry. It is what brings a poem to life it is the key to releasing all the emotions in us. Imagery develops a deeper meaning to the poem and its major themes. Plath uses a lot of images in her poem which reflect her feelings and help the reader to relate to her. The recurrences of related images are the central elements in Sylvia Plaths poetry. The poems of Daddy and Lady Lazarus both use imagery of historical people and events that took place to explain tense and painful emotions. The imagery she employs throughout both poems is intensely personal and centered around her intimate emotions. Due to this fact, this subsequently draws the attention more clearly to the themes of each poem. It is interesting to note that Daddy and Lady Lazarus were written only a fortnight apart, this may help to understand her state of mind at that time. It is conveyed through many related images in both of her poems. These specific images such as the Holocaust and her use of colour imagery effectively stress the themes of the poem which are primarily life and death. Daddy is a disturbing depiction of the father-daughter relationship- A relationship of the oppressor and the oppressed. Her fathers order and brutality is expressed in stereotypical images of a Nazi neat moustache, Mein Kempf look. In Daddy the main theme is that of death and fear. Poor and White is a stark contrast to the Black Shoe All her feeling and emotion has been sapped out by her father. The use of the colour Black represents death and negative images, it is the narrators mental and physical torture and ultimate destruction. This colour brings back the picture of her father. Strong images are used throughout this poem such as in the line Marble Heavy, a bag full of god,Frisco seal suggests the heaviness her fathers authority weighed on her throughout her life. This imagery would suggest that her father represented a threatening and domineering presence in her life. Once again, evoking the theme of fear in the poem. Plath uses the image of a vampire in Daddy to represent her husband and her father. Historically, people who were transformed into vampires became only  monsters who retained only the physical appearance of their former selves. The duality of father and husband in the poem correspond to the vampires dual identity as dead human and living monster. This image of a vampire effectively conveys the terror and intense negativity she is expressing in the poem. It is only natural that she would find an image which would link these two men in her life and using this further highlight the theme of suffering. Just like in Daddy, Sylvia Plath uses the imagery of colour Red Fire, Red Hair to denote one of her major themes. The colour Red is a fierce colour it represents life and vitality therefore it highlights the theme of Re-birth. Plath expresses her need to die in order to be re-born. Here she is confronting her pain through her poetry in an attempt to find internal peace. Images of Lazarus from the bible who was raised from the dead by Christ further highlights this theme of a revival. The theme of life and death is again apparent through her alteration from life to death to life again. The narrator has transformed psychologically in the course of her life, a transformation evident in her treatment and practice of suicide. The controversial Holocaust imagery only appears in the poems she wrote between October and November 1962 of which both Daddy and Lady Lazarus were written. It can be directly linked to the period when the Nazi Lieutenant was executed in 1962. In both poems she equates the horrors of personal suffering with the human suffering on a larger scale. The narrator utilizes a range of images of oppression which develop into horror images. Severely haunting images of the Holocaust such as Herr Doctor (figure of death) Chuffing me off like a Jew, Nazi Lampshade, the rack and the screw combined with the grotesque imagery peel off napkin skin, Full set of teeth. These disturbing images embody her turmoil and capture the essence of her desire to escape from life-which is death. The use of holocaustic imagery is intended to both shock and engage the audience, with strong associations and connotations of extreme horror and disgust. Plath uses these images as vehicles for creating an atmosphere of terror and evil and to further emphasize the theme of death. The definition of Theme is the pattern created within a literary work by the repetitive use of particular images. These images are laden with pain and the tragedy of suicide, the central tragedy of Sylvia Plath. The effect of Sylvia Plaths imagery stimulates a response from the reader. At the same time it allows the reader to draw on their own personal experience, this is the stage where the themes of a poem become clear. Plaths successful poetry can be attributed to her ability to express certain themes in such a diverse way. The theme of death is conveyed on many levels which are distinguished by the persona taking a subjective or objective view and using varied imagery to reflect what she is experiencing. Not only does the imagery in both poems develop the themes of life and death but they also can be seen to have other underlying meanings concerning the themes. After all why does Sylvia Plath concentrate on both the death and rebirth themes when clearly it is a paradox? Perhaps it suggests that maybe Sylvia Plath was as focused on living as she was absorbed by death. Nobody knows!

Spider Silk Is Natures Miracle Fiber

Spider Silk Is Nature's Miracle Fiber Spider silk is one of the most miraculous natural substances on Earth. Most building materials are either strong or elastic, but spider silk is both. Its been described as stronger than steel (which is not quite accurate, but close), more impenetrable than Kevlar, and stretchier than nylon. It withstands a lot of strain before breaking, which is the very definition of a tough material. Spider silk also conducts heat and is known to have antibiotic properties. All Spiders Produce Silk All spiders produce silk, from the tiniest jumping spider to the biggest tarantula. A spider has special structures called spinnerets at the end of its abdomen. Youve probably watched a spider constructing a web, or rappelling from a silk thread. The spider uses its hind legs to pull the strand of silk from its spinnerets, little by little. Spider Silk Is Made From Protein But what is spider silk, exactly? Spider silk is a fiber of protein, produced by a gland in the spiders abdomen. The gland stores silk protein  in liquid form, which isnt particularly useful for building structures like webs. When the spider needs silk, the liquefied protein passes through a canal where it gets an acid bath. As the pH of the silk protein is lowered (as its acidified), it changes the structure. The motion of pulling the silk from the spinnerets puts tension on the substance, which helps it harden into a solid as it emerges. Structurally, silk consists of layers of amorphous and crystalline proteins. The firmer protein crystals give silk its strength, while the softer, shapeless protein provides elasticity. Protein is a naturally occurring polymer (in this case, a chain of amino acids). Spider silk, keratin, and collagen are all formed of protein. Spiders will often recycle valuable silk proteins by eating their webs. Scientists have labeled silk proteins using radioactive markers and examined new silk to determine how efficiently spiders reprocess the silk. Remarkably, theyve found spiders can consume and reuse silk proteins in 30 minutes. Thats an amazing recycling system! This versatile material could have limitless applications, but harvesting spider silk isnt very practical on a large scale. Producing a synthetic material with the properties of spider silk has long been the Holy Grail of scientific research.   8 Ways Spiders Use Silk Scientists have studied spider silk for centuries, and have learned quite a bit about how spider silk is made and used. Some spiders can actually produce 6 or 7 kinds of silk using different silk glands. When the spider weaves a silk thread, it can combine these varied kinds of silks to produce specialized fibers for different purposes. Sometimes the spider needs a stickier silk strand, and other times it needs a stronger one. As you might imagine, spiders make good use of their silk-producing skills. When we think of spiders spinning silk, we usually think of them building webs. But spiders use silk for many purposes.   1. Spiders Use Silk to Catch Prey The best-known use of silk by spiders is for constructing webs, which they use to ensnare prey. Some spiders, like  orb weavers, construct circular webs with sticky threads to snag flying insects. Purse web spiders use an innovative design. They spin an upright silk tube and hide inside it. When an insect lands on the outside of the tube, the purse web spider cuts the silk and pulls the insect inside. Most web-weaving spiders have poor eyesight, so they sense prey in the web by feeling for vibrations traveling across the silk strands. A recent study showed that  spider silk can vibrate at a wide range of frequencies, allowing the spider to sense movements as small as a hundred nanometers- 1/1000 the width of a human hair. But thats not the only way spiders use silks to catch meals. The bolas spider, for example, spins a sort of fishing line of silk – a long thread with a sticky ball at the end. When an insect passes by, the bolas spider flings the line at the prey and hauls in its catch. Net-casting spiders spin a small web, shaped like a tiny net, and hold it between their feet. When an insect comes near, the spider throws its silk net and ensnares the prey. 2. Spiders User Silk to Subdue Prey Some spiders, like  cobweb spiders, use silk to subdue their prey completely. Have you ever watched a spider grab a fly or moth, and quickly wrap it in silk like a mummy? Cobweb spiders have special setae on their feet, which enable them to wind sticky silk tightly around a struggling insect.   3. Spiders Use Silk to Travel Anyone who read  Charlottes Web  as a child will be familiar with this spider behavior, known as ballooning. Young spiders (called spiderlings) disperse soon after emerging from their egg sac. In some species, the spiderling will climb onto an exposed surface, raise its abdomen, and cast a silk thread into the wind. As the air current pulls on the silk strand,  the spiderling becomes airborne and can be carried for miles. 4. Spiders Use Silk to Keep From Falling Who hasnt been startled by a spider descending suddenly on a silk thread? Spiders habitually leave a trail of silk line, known as a dragline, behind them as they explore an area. The silk safety line helps the spider keep from falling unchecked. Spiders also use the dragline to descend in a controlled manner. If the spider finds trouble below, it can quickly ascend the line to safety. 5. Spiders Use Silk to Keep From Getting Lost Spiders can also use the dragline to find their way home. Should a spider wander too far from its retreat or burrow, it can follow the silk line back to its home. 6. Spiders Use Silk to Take Shelter Many spiders use silk to construct or reinforce a shelter or retreat. Both  tarantulas  and  wolf spiders  dig burrows in the ground and line their homes with silk. Some web-building spiders construct special retreats within or adjacent to their webs. Funnel weaver spiders, for example, spin a cone-shaped retreat in one side of their webs, where they can stay hidden from both prey and predators. 7. Spiders Use Silk to Mate Before mating, a male spider must prepare and ready his sperm. Male spiders spin silk and construct small sperm webs, just for this purpose. He transfers sperm from his genital opening to the special web and then picks up the sperm with his pedipalps. With his sperm securely stored in his pedipalps, he can search for a receptive female. 8. Spiders Use Silk to Protect Their Offspring Female spiders produce particularly tough silk to construct egg sacs. She then deposits her eggs inside the sac, where they will be protected from the weather and potential predators as they  develop and hatch into tiny spiderlings. Most mother spiders secure the egg sac to a surface, often near her web. Wolf spiders dont take chances and carry the egg sac around until the offspring emerge.

Human relation - Essay Example In doing so, three factors have to be considered. These are: the effectiveness of Personal Communication, Communication in the work Place, and Getting along with your manager, coworker, and customers. How do these factors affect me in my personal environment and workplace? First let us have a definition of human relations. Dictionary meaning of the term defines it as â€Å"the study of group behavior for the purpose of improving interpersonal relationships, as among employees. It is further defined as â€Å"the skill or ability to work effectively through and with other people† (Lamberton, chap. 01, p.4). A separate description that I find more suitable states that human relations â€Å"includes all interactions with people whether it is conflict, cooperative effort or group relationships†. In a broader sense it is the study of why, beliefs, and attitudes that cause a strain in work-related relationship. So in the end, it emphasizes not only analysis of behavior, but provides strategies for prevention, resolution of the problems and self development (College. HMCO , 2008, ch. 01, p. 3, pdf) Several authors and studies point to factors that affect human relations in business. Lamberton, (chap.01, p.16 ) in his study, argued that human relations has two goals: one is for personal development and growth; and the other is for the accomplishment of the organization’s goals and objectives. In order to achieve these goals, the three areas of major importance in human relations that has to be understood are Personal Communication Effectiveness, Communication is described as an important element of human relations because it is the process of transferring of information from one person to another (Skills you need, 2014) .

Reflective report - Essay Example Postoperative anxiety is to be expected for these patients, and nurses and other health practitioners within the surgical ward are tasked with educating the patient about the surgery, providing emotional support, and reducing the emotional impact of the surgical procedure. Some of the other patients in the surgical ward are also undergoing postoperative care. Postoperative care for these patients include pain management, monitoring of vital signs, monitoring for bleeding, and monitoring for infection. In the case of the patient subject of this reflection, the patient is a 55 year old female patient who has recently undergone thyroidectomy. She is married, with 3 children, and has worked as a school teacher for 35 years. Six months ago she first noticed that there was a lump at her throat area. She ignored it at first, but four months prior to the surgery, the lump seemed to get bigger. Upon seeking medical consult, she was diagnosed with hyperthyroidism. This caused her goitre. After a month of treatment, her goitre continued to enlarge. Hence the thyroidectomy was scheduled. Post-operative pain medications were ordered for the patient by his attending surgeon. In this case, the controlled drug morphine was ordered. The patient registered pain levels on the scale of 1-10 (with 10 being the most severe) at 9/10. The pain was localized at the incision site at her throat area and she described it as a throbbing and persistent pain. She also registered pain when she would move. The administration of the morphine managed to reduce the pain levels to 3/10. Additional pain management included guided imagery where the patient was asked to picture pleasant scenarios as a means of distracting herself from the pain that she was feeling. I also checked the incision site for signs of bleeding and infection. I also monitored her blood pressure and vital signs. Her blood pressure as well as vital signs remained within normal levels within the postoperative period. The adminis tration of the morphine Oramorph SR was orally through a tablet every 12 hours. Based on hospital policy, no more than 2 tablets were administered to the patient within a 24 hour period. Morphine was also not administered when necessary as per hospital policy. An order by the attending physician was necessary before morphine could be administered. The nurses are required to instruct patients not to chew the tablets before swallowing because it can cause the release of the drug into the body all at once, possibly causing serious health issues, in some cases, death. The patient’s mouth was also washed after each administration. I was also asked to check for side or adverse effects of the drug, including: dizziness, lightheadedness, nausea, vomiting, diarrhoea, weight loss, dry mouth, headache, confusion, stiff muscles, mood changes, chills, and flu symptoms. More serious symptoms requiring immediate medical care included slow or irregular breathing, bluish coloration to the ski n, fast or slow heartbeat, seizures, hallucinations, blurred vision, hives, and rashes. Section 2 While caring for this patient, I was able to learn more about the protocols in the administration of the controlled drug morphine. The learning was able to emphasize the importance of understanding the application and use of controlled drugs, especially those used for pain relief (Hardwick, 2009). The
