Meaning and Argument shifts introductory logic from the traditional emphasis on proofs to the symbolization of arguments. Another distinctive feature of this book is that it shows how the need for expressive power and for drawing distinctions forces formal language development. This volume is ideal as an introduction to formal logic, philosophical logic, and philosophy of language. At each stage of system elaboration and development, the book answers metalogical questions. Why is a particular formalism needed? What must go into such a formalism and why? These questions engage students in a collective inquiry which allows them to see logical studies as a human enterprise aimed at achieving well understood purposes - clarity and good reasoning. This revised edition includes expanded sections, additional exercises, and an updated bibliography.Visit the book's website at: www .meaningargument.com
