Title: On American and Australian plans for negation

Abstract: Francesco Berto, later joined by Greg Restall, defends a modal account of negation, or the Australian plan for negation. The aim of this talk is to carefully examine and compare Australian and American plans for negation. To this end, I will consider four cases, and draw some implications for both plans. The four cases include (i) FDE-family, also with Shrieking and Shrugging idea deployed by Jc Beall, (ii) intuitionistic logic, (iii) treatment of Aristotle’s thesis, and (iv) the system CLoN made use of by Diderik Batens.
