Criticism of Benacerraf's criticism of modern eleatics

Leon, Antonio (2008) Criticism of Benacerraf's criticism of modern eleatics.

Abstract

I analyze here Benacerraf's criticism of Thomson arguments on the impossibility of w-supertasks. Although Benacerraf's criticism is well founded, his analysis of Thomson's lamp is incomplete. In fact, it is possible to consider a new line of argument, which Benacerraf only incidentally considered, based on the functioning laws of the lamp. This argument leads to a contradictory result that compromises the formal consistency of the w-ordering involved in all w-supertasks.
