Self-deception is a defining part of our human nature. By recognizing its various forms in ourselves and reflecting upon them, we may be able to disarm them and even, in some cases, to employ and enjoy them. This self-knowledge opens up a whole new world before us, rich in beauty and subtlety, and frees us not only to take the best out of it, but also to give it back the best of ourselves, and, in so doing, to fulfil our potential as human beings. I don't really think it's a choice.
