This chapter pursues a strategy for solving the knowability paradox in terms of the general category of the fallacies involved in substituting into intensional contexts. It clarifies and defends the indexical theory of quantification. It argues that the neo-Russellian view of quantification blocks the proofs from knowable truth to known truth (and from unknown truth to unknowable truth), and that the objections raised in the literature to this approach are not damaging.

Keywords: knowability paradox; substitutivity; intensional contexts; theory of quantification
