“[I]t is difficult to imagine a set of beliefs more suggestive of mental illness than those that lie at the heart of many of our religious traditions.”

“Given the link between belief and action, it is clear that we can no more tolerate a diversity of religious beliefs than a diversity of beliefs about epidemiology and basic hygiene.”

“It is taboo in our society to criticize a persons religious faith... these taboos are offensive, deeply unreasonable, but worse than that, they are getting people killed. This is really my concern. My concern is that our religions, the diversity of our religious doctrines, is going to get us killed. I'm worried that our religious discourse- our religious beliefs are ultimately incompatible with civilization.”

“Whatever their imagined source, the doctrines of modern religions are no more tenable than those which, for lack of adherents, were cast upon the scrap heap of mythology millennia ago; for there is no more evidence to justify a belief in the literal existence of Yahweh and Satan than there was to keep Zeus perched upon his mountain throne or Poseidon churning the seas.”

“A kernel of truth lurks at the heart of religion, because spiritual experience, ethical behavior, and strong communities are essential for human happiness. And yet our religious traditions are intellectually defunct and politically ruinous. While spiritual experience is clearly a natural propensity of the human mind, we need not believe anything on insufficient evidence to actualize it.”

“The problem I want to talk to you about tonight is the problem of belief. What does it mean to believe? We use this word all the time, and I think behind it lurk some really extraordinary taboos and confusions. What I want to argue tonight is that how we talk about belief- how we fail to criticize or criticize the beliefs of others, has more importance to us personally, more consequence to us personally and to civilization than perhaps anything else that is in our power to influence. ”

“It is time we recognized that belief is not a private matter; it has never been merely private. In fact, beliefs are scarcely more private than actions are, for every belief is a fount of action in potentia.”
