Sunday 13th December 1914: In his diary, LW reports that he worked all day at the office. ‘*My thoughts are lame*. I have muscle pain, and its also as if my brain was *limping*. But I did some work. Still no answer from David! Did he receive my letter? Is he as affected by the war as I am?! Only the Spirit lives! It is the safe harbour, protected, away from the dreary and endless grey sea of events’ (GT2, S.45). LW asks himself whether it exhausts the nature of negation that it is an operation that cancels itself. In that case, χ would have to stand for negation if χχp = p, as long as χp ≠ p. It’s certain that according to these two equations χ can no longer express affirmation. He wonders whether the capacity that these operations have of vanishing shows that they are logical (NB, p.36).
