It would be hard to deny that there is some modal doctrine in Wittgenstein's
Tractatus
, for the
Tractatus
contains the standard semantics for the classical propositional calculus and the standard semantics is modal. Moreover, the work makes serious use of modal concepts, especially that of a possible state of affairs (
möglich Sachverhalt
). Given the centrality of this notion, it is curious that commentators have so readily ignored the modal aspects of the
Tractatus
Raymond Bradley's excellent, full-blown study of Wittgenstein's early modalism is, therefore, all the more welcome as a corrective.
