WILLFUL STUPIDITY: “By indirection Finding Direction”
“The use of indirection to seek the truth, manipulation as opposed to direct action, is a significant theme in Hamlet, as it is used by each of the principal characters to pursue their own individual ends."
“I DEFINE STUPIDITY AS BEHAVING IN A WAY THAT IGNORES THE QUESTION: WHAT WOULD HAPPEN NEXT?”
David Brooks
Polonius suggests that "By indirections find directions out." By this, he means that his plot of Reynaldo using suggestion rather than direct interrogation will allow him to succeed in finding out the truth about Laertes. Essentially, subtlety is the best way of getting what he needs to know.
