abstract = {Mereology is widely defined as the theory of parthood, but as I shall explain it is better described as the theory of materiall parthood, where I use the adjective ‘material’ to mean concerned with the stuff of which things are made. Mereology was introduced by Leśniewski (1916) following his equally rigorous theories of protothetic and ontology (Simons 1987: 60–65) and, in a somewhat different and more accessible form as the Calculus of Individuals by Leonard and Goodman (1940), based on Leonard’s 1930 thesis ‘Singular Terms’. These systems are different ways of developing what I call classical mereology, which is mathematically equivalent to a complete Boolean algebra with the minimum element deleted – deleted because there is no null thing. There are many expositions of classical mereology but not as much has been written on alternatives. (See, however, Simons 1987: 81-92)). So in this article I shall briefly expound the classical theory, and then consider what sort of case can be made for or against classical mereology.},
