Hello Matthew (@ThouArtThat). Great to have you here.
While waiting for @Geoffreyjen_Edwards, @johnnydavis54 or others who may wish to answer your question, I post below the link to this recorded discussion/follow-up thread to this “Rethinking Time.” If recalling correctly, Whitehead was not mentioned in depth during the recording and the posts in the thread have some reference to Whitehead.
