The capacity to represent things to ourselves as possible plays a crucial role both in everyday thinking and in philosophical reasoning; this volume offers much-needed philosophical illumination of conceivability, possibility, and the relations between them.
I don't really know how to rate this book because I'm not entirely sure I understood everything. Very dense metaphysical philosophy.
Chapter 4 (Desire and Imagination) was very interesting, as was the chapter where the author offered a $100 prize to anyone who could show him a depiction of a logical impossibility.
