 The ‘accretion’ raises indeed an issue concerning ‘other minds’, given that it is one’s reflective view that, supposedly, authoritatively determines that one knows: could there be other ways to determine whether someone else knows? (See Longworth (2019).) This is how Austin, who also viewed knowledge as a state of mind, was arguably led to explore the ramifications the challenge ‘How do you know?’ to the person claiming ‘I know’. Although he warned against the ‘descriptive fallacy’ (Austin 1979, 103), Austin’s claim appears to be, rather, that ‘I know’ has functions “over and above describing the subjective mental state of knowing” (Longworth (2019, 195), see Austin (1979, 78–79)).
