Knowledge is an aid to happiness

"It is not true, in other words, that you’re only happy if you don’t know it. For this naively Romantic view, self-reflection is always fatally stymieing. It is what one might call the high-wire-act-across-an-abyss theory of life: think about it and you instantly come a cropper. But knowing how things stand with you is a necessary condition for knowing whether to try and change them or to keep them more or less as they are. Knowledge is an aid to happiness rather than its antagonist."
