The Second Edition of More Precisely is expected to appear in late 2017. It contains several new chapters.

More Precisely is a mathematics book that's designed to meet the needs of philosophers. More Precisely introduces the mathematical concepts you need in order to do philosophy today. As we introduce these concepts, we illustrate them with many classical and recent philosophical examples. This is math for philosophers.

More Precisely is not a philosophy of mathematics book. It's a mathematics book. We're not going to talk philosophically about mathematics. We are going to teach you the mathematics you need to do philosophy. We won't enter into any of the debates that rage in current philosophy of math. Do abstract objects exist? How do we have mathematical knowledge? We don't deal with those issues here.

More Precisely is not a logic book. We're not introducing you to any logical calculus. We won't prove any theorems. You can do a lot of math with very little logic. If you know some propositional or predicate logic, it won't hurt. But even if you've never heard of them, you'll do just fine here.

More Precisely is an introductory book. It is not an advanced text. It aims to cover the basics so that you're prepared to go into the depths on the topics that are of special interest to you. To follow what we're doing here, you don't need anything beyond high school mathematics. We introduce all the technical notations and concepts gently.

More Precisely is illustrated with many examples taken from many branches of philosophy - including metaphysics, philosophy of mind, philosophy of language, epistemology, ethics, and philosophy of religion. It shows how the mathematics is directly applied to philosophy.
