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.

The position of the Muslim community in the face of all provocations seems to be: Islam is a religion of peace, and if you say that it isn't, we will kill you.

It is still fashionable to believe that how you organize yourself religiously in this life may matter for eternity. Unless we can erode the prestige of that kind of thinking, we're not going to be able to undermine these divisions in our world.

Science has long been in the value business. Despite a widespread belief to the contrary, scientific validity is not the result of scientists abstaining from making value judgments; rather, scientific validity is the result of scientists making their best efforts to value principles of reasoning that link their beliefs to reality, through reliable chains of evidence and argument.

There must be right and wrong answers to questions of morality and values that potentially fall within the purview of science. On this view, some people and cultures will be right (to a greater or lesser degree), and some will be wrong, with respect to what they deem important in life.

We will see that the greatest problem confronting civilization is not merely religious extremism: rather, it is the larger set of cultural and intellectual accommodations we have made to faith itself.

Despite a full century of scientific insights attesting to the antiquity of the earth, more than half of our neighbors believe that the entire cosmos was created six thousand years ago. This is, incidentally, about a thousand years after the Sumerians invented glue.
