While religious tolerance is surely better than religious war, tolerance is not without its liabilities. Our fear of provoking religious hatred has rendered us incapable of criticizing ideas that are now patently absurd and increasingly maladaptive.

The same failure of liberalism is evident in Western Europe, where the dogma of multiculturalism has left a secular Europe very slow to address the looming problem of religious extremism among its immigrants. The people who speak most sensibly about the threat that Islam poses to Europe are actually fascists. To say that this does not bode well for liberalism is an understatement: It does not bode well for the future of civilization.

There's no way to reconcile Islam with Christianity. This difference of opinion admits of compromise as much as a coin toss does.

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).

It is utterly astonishing how ordinary a book can be and still be thought the product of omniscience.

Faith does not offer a strong link between our beliefs and actual states of the world.

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.
