How do we tell correct inferences based on faith from faulty ones? Without that it's mainly just a lottery as to what faith your parents happened to have.
I concur with his contention that "pretending" to know what you don't know is not correct for faith. I just think people with faith are completely oblivious to the fact that their reasons are not what they think they are. After all they're only human and it's probably true for most of us.
I've become convinced that people generally don't choose a faith, they choose a community and set of religious practices. Usually that's the one most familiar or accessible to them, and this draw towards community is a powerful instinct. How many of us are capable of making rational decisions that would lead us to be ostracised by our community and the people we love?
Boghossian does sound like a bit of an arse though.
