The rider and the ridden

The difficulty lies in learning that we ourselves encompass forces equally great. We say, “I will,” and “I will not,” and imagine ourselves (though we obey the orders of some prosaic person every day) our own masters, when the truth is that our masters are sleeping. One wakes within us and we are ridden like beasts, though the rider is but some hitherto unguessed part of ourselves.
― Gene Wolfe, Shadow & Claw
