On p. 121 of "Quaestio Subtilissima", D. P. Henry proposes this formalisation of i. The Nothing noths (He distinguishes this from ii. The nothing noths.) iii. ͻ[[Λ]](Λ) The use of "[[...]]" Henry borrows from Oxford philosopher A. N. Prior. On p. 120, he notes that the 'the' "portents some sort of singularity", which Henry symbolises as iv. sol(Λ) Henry says that (iv) justifies "the use of the capital initial letter". Henry concludes the section on Heidegger with the remark that (i) can thus be seen as being sensical and "a truth derivable from the deductive metaphysics" which he is constructing. I agree with J. L. Scherb that this was a "pre-war debate" (pre-Second World War) between Rudolf Carnap and Martin Heidegger about allegedly (as D. P. Henry has it) meaningless metaphysical statements such as "The Nothing noths" ("Das Nichts nichtet"). Within the mainstream of 20th century analytical philosophy this statement, "The Nothing noths" has come to be regarded as obvious metaphysical nonsense. And it was Sir Freddie Ayer who brought the news to Oxford. It is said that Oxford could not BEAR with the 'enfant terrible' -- but I WOULD distinguish between a Carnapian scientist approach and Ayer's, which was directed towards empiricist epistemoly in general -- and Ayer did not stay at Oxford for long, finding a post in London. In terms of the history of philosophy, this is seen as Oxford never having 'bought' the idea that metaphysical statements were, as Ayer thought he had shown, after Carnap, 'meaningless'. There were hordes of philosophers practicising metaphysics THEN (think Collingwood) as there are hordes of philosophers practising metaphysics NOW at Oxford As we all know, this led to an unfortunate confrontation between analytical and continental philosophy -- with Sartre assuming the Heideggerian position and generalising it: "Das Nichts nichtet" and consciousness is "le néant néantisant". The judgement of "The Nothing noths" as nonsense was somewhat 'corrected' by D. P. Henry. But the conflict still seems to exist. Henry's remark didn't find its way to a greater audience, because Henry didn't *prove* his claim in a canonical way, and because Henry's remark may be alleged to contains an ambiguity, which may give rise to criticism. The required disambiguation, together with the missing proofs, can be given within the ontology introduced by Stanisław Leśniewski -- notably protothetic -- that Grice adored ("protothetic (why?)" -- "Aspects of Reason" -- Grice had a taste for a Polish neologism). Ludger Honnefelder calls the systems Stanisław Leśniewski, which were developed roughly at the same pre-war time (1913-1939), a new beginning of metaphysics. They systems of Stanisław Leśniewski (that Henry learned via Geach -- whose mother was Polish) provide the missing link (to use a metaphor) between Heidegger and Carnap (and Ayer). The systems of Stanisław Leśniewski can thus be regarded as an ontological (if not metaphysical) supplement to and a partial correction of Michael Friedman's essay on Heidegger, Carnap and Cassirer. A hermeneutical conclusion may be drawn from this that allows for a reconciliation between two types of philosophy. This is possible not only in terms of Cassirer's observations, but also along the lines of "logical form", broadly conceived -- as Henry suggested. The hermeneutical outcome suggests that one CAN make use of PRECISE logic tools in a more general way than Carnap himself allowed (if not Ayer and less so Grice), alla D. P. Henry, without having to declare that at a few central statements of Heidegger's Fundamentalontologie are pure nonsense -- but rather pretty illuminating -- if you think of them ("and even if you don't").
