I generally admire the work of Geoffrey Hellman , so I was excited to read his preprint titled Mereology in Philosophy of Mathematics , to be included in Handbook of Mereology . While the paper is well-written and quite informative, I find it highly disappointing in terms of whom it gives credit to. When talking about using mereology in metatheory in order to describe the syntax of a given system, Hellman writes: In their "Steps Toward a Constructive Nominalism", Goodman and Quine used mereology along with a short list of syntactic primitive predicates of concrete marks or inscriptions intended to reconstruct enough formal syntax of mathematical language to serve as the basis of a formalist, nominalistic account of mathematics as a symbolic, rule-governed activity... thus crediting Goodman and Quine with this approach. (Goodman and Quine are also often wrongly credited with the formulation of Mereology). Nowhere in his paper does ...
