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… - Sam Harris

There is no doubt that the United States has much to atone for, both domestically and abroad...To produce this horrible confection at home, start with our genocidal treatment of the Native Americans, add a couple hundred years of slavery, along with our denial of entry to Jewish refugees fleeing the death camps of the Third Reich, stir in our collusion with a long list of modern despots and our subsequent disregard for their appalling human rights records, add our bombing of Cambodia and the Pentagon Papers to taste, and then top with our recent refusals to sign the Kyoto protocol for greenhouse emissions, to support any ban on land mines, and to submit ourselves to the rulings of the International Criminal Court. The result should smell of death, hypocrisy, and fresh brimstone.

A three-day-old human embryo is a collection of 150 cells called a blastocyst. There are, for the sake of comparison, more than 100,000 cells in the brain of a fly. If our concern is about suffering in this universe, it is rather obvious that we should be more concerned about killing flies than about killing three-day-old human embryos… Many people will argue that the difference between a fly and a three-day-old human embryo is that a three-day-old human embryo is a potential human being. Every cell in your body, given the right manipulations, every cell with a nucleus is now a potential human being. Every time you scratch your nose, you’ve committed a holocaust of potential human beings… Let’s say we grant it that every three-day-old human embryo has a soul worthy of our moral concern. First of all, embryos at this stage can split into identical twins. Is this a case of one soul splitting into two souls? Embryos at this stage can fuse into a chimera. What has happened to the extra human soul in such a case? This is intellectually indefensible, but it’s morally indefensible given that these notions really are prolonging scarcely endurable misery of tens of millions of human beings, and because of the respect we accord religious faith, we can’t have this dialogue in the way that we should. I submit to you that if you think the interests of a three-day-old blastocyst trump the interests of a little girl with spinal cord injuries or a person with full-body burns, your moral intuitions have been obscured by religious metaphysics.

Anyone who believes that God is watching us from beyond the stars will feel that punishing peaceful men and women for their private pleasure is perfectly reasonable.
