Abstract

Putnam tried to deploy model theory to deny the legitimacy of metaphysical external realism. In the ‘indeterminacy’ strand, he levelled three criticisms: permutation, Skolemisation, and constructivisation. Against Putnam's programme, Bays has posited a metamathematical dilemma which could serve to yield a way out for the external realist. Against Bays' dilemma I shall defend the metamathematical legitimacy of Putnam's arguments by showing that it is always perfectly adequate to assume weaker theories than the external realist's theory, which forces him to acknowledge unintended models for his theory. I therefore argue that all the arguments are immune to metamathematical objections, and so, that Putnam’s arguments remain strong against the external realist agenda.
