Abstract. We distill Penrose’s argument against the “artificial intelligence premiss”, and analyze its logical alternatives. We then clarify the different positions one can take in answer to the question raised by the argument, skirting the issue of introspection per se. 1 The Argument It follows that there are four sons: one wise; and one wicked; one simple; and who knows not how to ask. —Mekhilta of R.
