Act III, scene III in Shakespeare's Othello is THE most important scene in the whole play. During the progression of the scene Iago sets his master plan in stone by taking away the good in Othello and bringing out his war like nature. However, these mind-changing tactics Iago uses are not simple and not on a whim. Iago's plan is extremely well crafted, well thought out, and carefully executed.

             Iago's second device of mind programming comes into play when, from lines 260-277, he blatantly te...
