It is taboo in our society to criticize a persons religious faith... these taboos are offensive, deeply unreasonable, but worse than that, they are getting people killed. This is really my concern. My concern is that our religions, the diversity of our religious doctrines, is going to get us killed. I'm worried that our religious discourse- our religious beliefs are ultimately incompatible with civilization.

Religious faith obscures uncertainty where uncertainty . . . exists, allowing the unknown, the implausible, and the . . . false to achieve primacy over the facts.

Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches.

Missionaries in the developing world waste a lot of time and money (not to mention the goodwill of non-Christians) proselytizing to the needy. . . . While missionaries do many noble things at great risk to themselves, their dogmatism still spreads ignorance and death. By contrast, volunteers for secular organizations . . . do not waste . . . time telling people about the virgin birth of Jesus. Nor do they tell people in sub-Saharan Africa - where nearly four million people die from AIDS every year - that condom use is sinful.

If you are perpetually angry, depressed, confused, and unloving, or your attention is elsewhere, it won't matter how successful you become or who is in your life - you won't enjoy any of it.

Advance warning of Katrina's path was wrested from mute Nature by meteorological calculations and satellite imagery. God told no one of His plans. Had the residents of New Orleans been content to rely on the beneficence of God, they wouldn't have known that a killer hurricane was bearing down upon them until they felt the first gusts of wind on their faces. And yet, as will come as no surprise to you, a poll conducted by The Washington Post found that 80 percent of Katrina's survivors claim that the event only strengthened their faith in God.

Life is a continuous flux. Our nonhuman ancestors bred, generation after generation, and incrementally begat what we now deem to be the species homo sapiens - ourselves. There is nothing about our ancestral line or about our current biology that dictates how we will evolve in the future. Nothing in the natural order demands that our descendants resemble us in any particular way. Very likely, they will not resemble us. We will almost certainly transform ourselves, likely beyond recognition, in the generations to come.
