“Constructionism is the recognition, backed up by the last half century of brain research, that people don’t passively take in reality. Each person actively constructs their own perception of reality. That’s not to say there is not an objective reality out there. It’s to say that we have only subjective access to it. “The mind is its own place,” the poet John Milton wrote, “and in itself / Can make a Heaven of Hell, a Hell of Heaven.”
