“Environments are invisible.”
That’s Marshall McLuhan’ overarching big idea. We are fundamentally, almost inherently, unable to see the largest thing in our lives — our environment. This ocean of ideas, assumptions, expectations, constraints, drivers, beliefs, blinders, and influences that shape our lives and minds is hidden from us precisely because we are in it and of it. It takes a peculiar stance and foolishness to step outside it long enough to perceive it.
Marshall McLuhan was strange and clownish enough to see it.
