Classification looks at a diverse group of objects (a heterogeneous group) and looks for similarities. The writer then creates categories based on those similarities and labels each category. Humor is often, but not always, the intent of writing a classification essay. For example, a student may choose to write an essay classifying students at her school. Such categories may include any of the following: the overachievers, the techies, the jocks, and the club rats. The writer would describe each of these categories in a paragraph, using humorous language and giving examples.
Because rhetoric is a public art capable of shaping opinion, some of the ancients including Plato found fault in it. They claimed that while it could be used to improve civic life, it could be used equally easily to deceive or manipulate with negative effects on the city. The masses were incapable of analyzing or deciding anything on their own and would therefore be swayed by the most persuasive speeches. Thus, civic life could be controlled by the one who could deliver the best speech. Plato explores the problematic moral status of rhetoric twice: in Gorgias , a dialogue named for the famed Sophist, and in The Phaedrus , a dialogue best known for its commentary on love. This concern is still maintained to nowadays.
The speech "I Have a Dream," by Martin Luther King Jr., succeeds in illustrating the racist problems of the time, provoking the audience into feeling sympathetic as well as providing hope to the depressed African-American population. He builds his arguments brilliantly and persuasively by utilizing anaphora, metaphor and establishing ethos.
First and foremost, the phrase "Now is the time" is repeated three times in three successive sentences in the speech. This repetition efficaciously delivers and reinforces the message that the speech is aimed to offer: righteous and immediate act is requisite at that time, when "the Negro is still not free", when "the Negro is still sadly crippled by the manacles of segregation and the chains of discrimination" and that it is easily observed that "America has defaulted on this promissory note so far as her citizens of color are concerned". More specifically, the black Americans is still treated with severe racial prejudice and suffers from miserable lives. Therefore, "fierce urgency" towards drastic measures is of absolute magnitude in order to improve and resolve the alarming situation. As a result, King’s crucial idea, which highlights the utter significance of instant action, seeps into people's consciousness and gathers strength through the expressive repetition and emphasis. Additionally, this rhetorical skill also effectively ameliorates the presentation's rhythm, structure and flow.
King's argument is also logically furthered by his skillful use of metaphor: "Now is the time to rise from the dark and desolate valley of segregation to the sunlit path of racial injustice. Now is the time to lift our nation from the quicksands of racial justice to the solid rock of brotherhood." Here, King compares discrimination as "the dark and desolate valley" and "the quicksands" while equality is referred to "the sunlit path" and "the solid rock". Unpleasant, dangerous and depressing images can be deduc...
