I wholeheartedly recommend
Ontology and Metaontology: A Contemporary Guide (2015) by Francesco Berto and Matteo Plebani. It's hot off the press!
Full disclosure: I know the author well.
- The pros: It written very clearly.
- The cons: It goes into some detail.
The blurb gives a sense of the content and the intended audience:
Ontology and Metaontology: A Contemporary Guide is a clear and accessible survey of ontology, focusing on the most recent trends in the discipline.
Divided into parts, the first half characterizes metaontology: the discourse on the methodology of ontological inquiry, covering the main concepts, tools, and methods of the discipline, exploring the notions of being and existence, ontological commitment, paraphrase strategies, fictionalist strategies, and other metaontological questions. The second half considers a series of case studies, introducing and familiarizing the reader with concrete examples of the latest research in the field. The basic sub-fields of ontology are covered here via an accessible and captivating exposition: events, properties, universals, abstract objects, possible worlds, material beings, mereology, fictional objects.
The guide's modular structure allows for a flexible approach to the subject, making it suitable for both undergraduates and postgraduates looking to better understand and apply the exciting developments and debates taking place in ontology today.
