The term essay hooks is the introductory part of the essay that grabs the reader’s attention. It gives him a chance to decide and make up his mind whether to continue reading your work or not. The hooks for essays are actually the baits for readers. While writing any essay, one has to make sure that the topic you choose and the overall article must be appealing to the audience. This way one will be able to grab the attention of readers. It is an interesting sentence or phrase that captures the attention and glues the reader to your piece of writing.
If we substitute for a frog a "Mr. Goodwill" or a "Mr. Prudence," and for the scorpion "Mr. Treachery" or "Mr. Two-Face," and make the river any river and substitute for "We're both Arabs . . ." "We're both men . ." we turn the fable [which illustrates human tendencies by using animals as illustrative examples] into an allegory [a narrative in which each character and action has symbolic meaning]. On the other hand, if we turn the frog into a father and the scorpion into a son (boatman and passenger) and we have the son say "We're both sons of God, aren't we?", then we have a parable (if a rather cynical one) about the wickedness of human nature and the sin of parricide.
