Great introduction to certain issues in Philosophy
Mates does an excellent job introducing the issues he tackles in this slim but dense volume. He covers a lot of the responses that I had always assumed handled these problems and then shows how they have failed. Although this is not an introduction to Skepticism, it is a fine example of how Skeptical thinking is applied to a specific set of issues within Philosophy. I might even recommend it for someone with no background in Philosophy. There are a few really technical areas that might confuse someone with no training, but on the whole, anyone who really wants to understand it can, with patience and access to the various Encyclopedias of Philosophy available on the internet - including Stanford's Encyclopedia of Philosophy and The Internet Encyclopedia of Philosophy - will be able to understand and be enriched by this book.
