In that speech, Mitchell poses three questions that, to me,
demonstrate the difference between superficial thinking
and deep thinking.

If our goal is to communicate,
if our goal is to persuade, and we were challenged
to answer the following three questions,
how might we respond?

I found it to be a difficult exercise.

1) “How would you suggest
     that it is better to suffer an injustice than to do one?”

2) “What line of reasoning
     would you use to demonstrate that there must be some
     difference between what we know and what we believe?”

3) “How does one test
     the proposition that there is some difference between
     what we know and what we believe?”

The goal of communication
is to cause another person to see in their own mind what you see in yours.

The goal of persuasion
is to cause another person to believe what you believe.
Unless, of course, you are lying. Then the goal is to cause
another person to believe what you, yourself, do not.

These are big and pungent ideas.
When you explore ideas like these in a 3-day workshop and learn time-tested techniques in visual and verbal communication and persuasion,  you’re obviously at The Magical Worlds Communications Workshop at Wizard Academy.
