Beyond Substitution—An Antipositionalist's Guide to Subtraction—
Philosophy and Phenomenological Research, EarlyView.ABSTRACT Existing accounts of relations do not properly account for variably polyadic relations: they fail to capture the relationship between completions of the same relation by different numbers of relata. This paper develops a fully general account of such relations by adding an operation of subtraction to the antipositionalist theory of relations ...
