Good evening ladies and gentlemen. Welcome to session #13. Lecture 13 will be the longest lecture I have to present in this course. It’s in four parts: 13A now, 13B and C next Thursday, 13, part D will be in the final workshop session. And the reason I don’t give it all at one time, it would take, obviously, too long. The subject of Lecture 13, essentially, is to demonstrate the potency of the lone acting individual.
