More Precisely provides a friendly, thorough introduction to the mathematics necessary to do philosophy. It is impossible to fully understand much of the most important work in contemporary philosophy without a basic grasp of set theory, functions, probability, modality and infinity. But until now, this knowledge was difficult to acquire. Professors had to provide custom handouts to their classes, while students struggled through math texts searching for insight. Eric Steinhart provides a unique introduction to the mathematics needed to do philosophy. He explains the basic mathematical concepts; sets out the most commonly used notational conventions; and, demonstrates how mathematics applies to many fundamental issues in branches of philosophy such as metaphysics, philosophy of language, logic and ethics.
