"Pietruszczak's new book covers all vital theories within mereology ... . A number of theories have been presented for the first time. It is especially worth mentioning that Andrzej Grzegorczyk's mereological theories have been analysed, elaborated and significantly improved by Pietruszczak." (Marcin Tkaczyk, Studia Logica, Vol. 109, 2021)

"Each chapter of the book is structured in a similar way and contains the basic definitions, facts and necessary discussion regarding the key notions, accompanied with new ideas and a wide reference list, followed by the author's clear and approachable style."
