Last week was a gathering of physicists in Oxford to discuss string theory and the philosophy of science.

From the article:

Nowadays, as several philosophers at the workshop said, Popperian falsificationism has been supplanted by Bayesian confirmation theory, or Bayesianism...

Gross concurred, saying that, upon learning about Bayesian confirmation theory from Dawid’s book, he felt “somewhat like the Molière character who said, ‘Oh my God, I’ve been talking prose all my life!’”

That the Bayesian view is news to so many physicists is itself news to me, and it's very unsettling news. You could say that modern theoretical physics has failed to be in-touch with other areas of science, but you could also make the argument that the rationalist community has failed to properly reach out and communicate with scientists.

The character from Molière learns a fancy name ("speaking in prose") for the way he already communicates. David Gross isn't saying that he is unfamiliar with the Bayesian view, he's saying that "Bayesian confirmation theory" is a fancy name for his existing epistemic practice.
