There is no reason for believing that any sort of gods exist, and quite good reasons for believing that they do not exist and never have. It has all been a gigantic waste of time and a waste of life. It would be a joke of cosmic proportions if it weren't so tragic.

The psychologist Elizabeth Loftus has shown great courage, in the face of spiteful vested interests, in demonstrating how easy it is for people to concoct memories that are entirely false but which seem, to the victim, every bit as real as true memories.

Evolution is a very, very important idea. It is the explanation for all of life - a stunningly simple, yet powerful explanation. If you think about it, before Darwin, we hadn't the foggiest idea of how we came into being. Now we do. It's still such an exciting idea that it is well worth everybody understanding it.

Science tells us what we have reason to believe. Not what we have a duty to believe. Not what experts, in their pontificating wisdom, instruct us to believe... No, science tells us what there is good reason to believe.

When you plant a fertile meme in my mind you literally parasitize my brain, turning it into a vehicle for the meme's propagation in just the way that a virus may parasitize the genetic mechanism of a host cell.

Faith is the lack of evidence, and it shouldn't be that difficult to convince people that the right reason to believe something is that there is evidence for it. People do not innately go for this view, but nevertheless it is not that difficult to teach.

I think that [Paul] Bloom's approach - and others who take it - is not so much that there is a precise genetic basis to faith. But there is a genetic basis to a psychological predisposition that manifests itself as faith and religion under the right conditions.
