Although science may ultimately show us how to truly maximize human well-being, it may still fail to - Sam Harris

It is generally argued that our experience of free will presents a compelling mystery: On the one hand, we can't make sense of it in scientific terms; on the other, we feel that we are the authors of our own thoughts and actions.

It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. You are, of course, free to interpret the Bible differently—though isn't it amazing that you have succeeded in discerning the true teachings of Christianity, while the most influential thinkers in the history of your faith failed?

And then came the insight that irrevocably transformed my sense of how good human life could be. I was feeling boundless love for one of my best friends, and I suddenly realized that if a stranger had walked through the door at that moment, he or she would have been fully included in this love. Love was at bottom impersonal — and deeper than any personal history could justify. Indeed, a transactional form of love — I love you because. . . — now made no sense at all.
