This volume tackles the slippery subject of 'meaning'.

Hyperproof is a system for learning the principles of analytical reasoning and constructing proofs. It is intended for use in conjunction with a presention of the formal syntactic system of first-order propositional logic, especially the authors' software program, "Tarski's World".

A method of introducing students to the language of first-order logic. It helps students learn the meanings of connectives and qualifiers and soon become fluent in the symbolic language at the core of modern logic.

Information is a central topic in computer science, cognitive science and philosophy. In spite of its importance in the 'information age', there is no consensus on what information is, what makes it possible, and what it means for one medium to carry information about another. Drawing on ideas from mathematics, computer science and philosophy, this book addresses the definition and place of information in society. The authors, observing that information flow is possible only within a connected distribution system, provide a mathematically rigorous, philosophically sound foundation for a science of information. They illustrate their theory by applying it to a wide range of phenomena, from file transfer to DNA, from quantum mechanics to speech act theory.
