This is approximately the talk I gave on October 3rd at the Atheist Alliance International convention. You see, that presentation was not recorded; so I did it myself, a few days later, at home in Sacramento. Therefore, this video shows something similar to what you would have seen in Burbank. Here is an abstract:

As Wittgenstein observed, “one cannot mean a senseless series of words.” Religious propositions have no meaning, so they cannot be meant; and if they cannot be meant, they cannot be believed. One cannot believe a pseudo-proposition. “I believe in God” (for example) sounds like a report of an internal state, but that cannot be exactly what it is. What, then, is it, really? If the person making this statement it is not meaning or believing, what are they doing? Here at last is a question about religion that can be answered! Such “professions” are not reports of private mental states, they are public tokens of affiliation. Thus, the “sincerely held beliefs” paradigm used throughout our society (in Title VII of the Civil Rights Act, for example) is wildly inaccurate. This has important implications for cultural debate and for public policy.
