As a describer of life and manners, he must be allowed to stand perhaps the first of the first rank. His humour, which, as Steele observes, is peculiar to himself, is so happily diffused as to give the grace of novelty to domestic scenes and daily occurrences. He never "o'ersteps the modesty of nature," nor raises merriment or wonder by the violation of truth. His figures neither divert by distortion nor amaze by aggravation. He copies life with so much fidelity that he can be hardly said to invent; yet his exhibitions have an air so much original, that it is difficult to suppose them not merely the product of imagination.
You present a persuasive argument for the abandonment of the 5-paragraph essay and suggest a new format for presenting an argument... However, you did not provide much information on what is expected to go in between your introduction and conclusion? You suggested this format opens the essay to compare/contrast, cause/effect, analysis, etc... but how do you suggest students structure an essay with these approaches in practice? Any piece of writing needs some structure and main ideas that are then supported with various pieces of evidence (whether you are writing a historical thesis or a persuasive essay)... If you are abandoning a "main idea followed by supporting evidence" format, what do you propose should take its place? Or perhaps my understanding of the 5-paragraph essay you are speaking of is incorrect?
Throughout its history humankind asked itself this question and constantly tried to answer “no”. The idea of sentient living beings who are not people is present in writings of historians, geographers and other scientists for as long as the science itself exists. Mermaids, cynocephali, various bizarre species of beastmen, antipodes: all of them were embodiments of this dream. In course of time, the limits of the known Universe expanded and it became known that no such creatures existed. The only place to seek for non-human life now is other planets. Is there any hope for finding it?
