There's a dark truth lurking behind our perception. We know that if we command a muscle to flex, it will flex. If we choose to say something, our mouths will respond. To our imperfect minds, free will is self-evident. But many scientists believe that all of our choices, even if they appear to be conscious, are actually the product of outside stimuli--things like conditioning and environmental factors.
Nobody is sure how much of this is true. We know that the illusion is real, but we don't know to what extent. We could be like computers, incapable of taking any action that wasn't already programmed into us, or we could operate on a combination of learned behaviors, instincts, and physical autonomy. That's not something we can test without delving deeper into the human mind. Either way, we can be brainwashed, and we would never know it was happening.
Instead, we'd a giant revelation crashing down on our heads, shattering our old preconceptions. We could find ourselves on our knees, sobbing and begging the Lord for forgiveness while a man in a pulpit tells us how to live. We might encounter an extraordinary individual--some might say a messiah--or a special group of friends--people with a common purpose.
