Harro: let me complicate things a little more.
There is a clear discontinuity in the
evolution of Knight's thought -- a "break" which
came immediately after the publication
of RUP. The main focus of Knight's "recantation"
-- as he called it in a long letter to
Viner -- concerns Knight's change of attitude
towards behaviorism (which is in turn
related to Knight's reading of Mach and
Poincarč). I wonder if this was also the cause
of his decline of interest toward the general
issue of uncertainty. I recently published
a little note on this which might help you also
in connection to Bergson's influence.
