β¦ Synopsis
This paper, which began as a comment on a talk by Drew McDermott, 1 was completed in the summer of 1980. It circulated in typescript, but was not published at the time. A lot has happened in the study of nonmonotonic reasoning since that time, and the paper is now quite dated, but it is being published now, just to put it on the record, since it has been widely cited (mainly as a result of citations in Robert Moore's influential work on autoepistemic logic). Other than grammatical, typographical and notational corrections, and a few cautionary comments added to endnotes, the paper is unchanged from the 1980 version. 2

## Abstract Grzegorczyk's modal logic (Grz) corresponds to the class of upwards wellβfounded partially ordered Kripke frames, however all known proofs of this fact utilize some form of the Axiom of Choice; G. Boolos asked in [1], whether it is provable in plain ZF. We answer his question negatively
## Abstract Dualβintuitionistic logics are logics proposed by Czermak (1977), Goodman (1981) and Urbas (1996). It is shown in this paper that there is a correspondence between Goodman's dualβintuitionistic logic and Nelson's constructive logic N^β^.
