Parts

The relationship of part to whole is one of the most fundamental there is; this is the first and only full-length study of this concept. This book shows that mereology, the formal theory of part and whole, is essential to ontology. Peter Simons surveys and criticizes previous theories, especially the standard extensional view, and proposes a more adequate account which encompasses both temporal and modal considerations in detail.

'Parts could easily be the standard book on mereology for the next twenty or thirty years.' Timothy Williamson, Grazer Philosophische Studien
