“A belief most people around me don't share…”

Marshall McLuhan used the word probe to describe his way of approaching problems. “Most of my work is like that of a safecracker,” he said. “In the beginning I don't know what's inside. I just set myself down in front of the problem and begin to work. I grope, I listen, I test, I accept and discard; I try out different sequences—until the tumblers fall and the doors spring open.”
Like the unmanned probes we send into deep space, a probe lands in unfamiliar territory and returns something of value. Not an answer—an opening. They make us think: there is more there.
In 1970, McLuhan remarked: “The problem of private identity vs. tribal involvement has become one of the crosses of our time.” He named a tension but didn't resolve it. A perfect probe.

The course is built around more than 8 new probes from Luke—probes that go further than the book could. Each module opens with one, and the course is designed to make sure the tumblers fall and the doors spring open.
