"An exciting, well-written, fun introduction to contemporary ontology."Choice Magazine"This is a delightful introduction, both to various ontological topics and to the general aims and methods of ontology itself. Effingham writes with an informal style and a lightness of touch that makes even the more esoteric and technical issues come alive, and the book is an instructive joy to read."Helen Beebee, University of Manchester"Nikk Effingham has done a terrific job - he provides fine, clear introductions to a range of important debates, woven through with methodological reflections, whilst his chatty, engaging style conveys the sheer pleasure of becoming an ontologist."Katherine Hawley, University of St Andrews
