What we do in every other area of our lives (other than religion), is, rather than respect somebody's beliefs, we evaluate their reasons.

To say that I would have done otherwise had I wanted to is simply to say that I would have lived in a different universe had I been in a different universe.

All I'm arguing for really is that we should have a conversation where the best ideas really thrive, where there's no taboo against criticizing bad ideas, and where everyone who shows up, in order to get their ideas entertained, has to meet some obvious burdens of intellectual rigor and self-criticism and honesty-and when people fail to do that, we are free to stop listening to them. What religion has had up until this moment is a different set of rules that apply only to it, which is you have to respect my religious certainty even though I'm telling you I arrived at it irrationally.

Some propositions are so dangerous that it may even be ethical to kill people for believing them.

The problem of vindicating an omnipotent and omniscient God in the face of evil is insurmountable. Those who claim to have surmounted it, by recourse to notions of free will and other incoherencies, have merely heaped bad philosophy onto bad ethics.

How can we encourage other human beings to extend their moral sympathies beyond a narrow locus? How can we learn to become mere human beings, shorn of any more compelling national, ethnic, or religious identity? We can be reasonable. It is in the very nature of reason to fuse cognitive and moral horizons. Reason is nothing less than the guardian of love.

Faith enables many of us to endure life's difficulties with an equanimity that would be scarcely conceivable in a world lit only by reason.
