So Marxism, Freudianism: any one of these things I think is an irrational cult. They're theology, so they're whatever you think of theology; I don't think much of it.

No one seriously doubts that if Piraha children are brought up in Boston they'll be speaking Boston English, that is, that the capacities are present, unlike other animals, as far as is known.

Very commonly I get queries. Somebody saw something of mine on YouTube and of course if there is a talk on YouTube, there aren't any footnotes - and they want to know why did you say this.

If they ask for evidence, I just say well take a look and mention something they can read and that usually ends the conversation.
