Upon publication reception of the volumes was positive. A review in
Ethics by Jeffrey Zekauskas noted that the volumes can clarify and aid in understanding Wittgenstein's
Philosophical Investigations, adding that they are "significant additions to Wittgenstein's published corpus as well as to the contemporary literature in the philosophy of mind".
Ian Hacking, in the
New York Review of Books speculated that the volumes "may well turn out to be his most enduring secondary work, fair companions to the only books that Wittgenstein did cast into final form". ==See also==
