Only the first two sentences of p. 1 published: 7.36n13. This is apparently an earlier draft of MS. 690. Moreover it appears that pp. 3-9 were lifted from here and incorporated in MS. 690. This is not the case, however, with pp. 16-18, which are still missing. Personal anecdote (same as in MS. 687).
Autobiographical references, Guessing, Logic (modal see Modality)
pp. 1-22 (pp. 3-9 16-18 missing) plus pp. 1-2 (rejected) of another start
