A Reaction

Simons catalogues several other modern attempts at axiomatisation in his chapter 2.


The 9 ideas with the same theme [basic principles for reasoning about parts and wholes]:

A part of a part is a part of a whole [Hobbes]
y is only a proper part of x if there is a z which 'makes up the difference' between them [Yablo]
We might combine the axioms of set theory with the axioms of mereology [Fine,K]
Which should be primitive in mereology - part, or overlap? [Sider]
Two standard formalisations of part-whole theory are the Calculus of Individuals, and Mereology [Simons]
Classical mereology doesn't handle temporal or modal notions very well [Simons]
The part-relation is transitive and asymmetric (and thus irreflexive) [Simons]
Each wheel is part of a car, but the four wheels are not a further part [Simons]
Extensional mereology needs two definitions and two axioms [Hossack]
