1.) Rewrite the following sorite in standard form, including a symbolization key of the letters you use to represent the categories. Show by means of appropriately labelled Venn diagrams that (vi) follows validly from (i)-(v):
(i). All writers who understand human nature are clever.
(ii). No one is a true poet unless he can stir the hearts of men.
(iii). Shakespeare wrote Hamlet.
(iv). No write who does not understand human nature can stir the hearts of men.
(v). None but a true poet could have written Hamlet.

(vi). Shakespeare was clever.
...my informal perspective:
Shakespeare is a true poet because he wrote Hamlet
Shakespeare can stir the heart of men because he is a true poet
Hamlet the work of a true poet, Shakespeare, stirs the heart of men and thus understands human nature
Thus if given all writers who understand human nature are clever, and Shakespeare, the poet/writer, understood human nature in Hamlet, one necessarily concludes that Shakespeare must be clever !
...now get the symbols in place...do something !
