Klappentext zu „Three Views of Logic “
Demonstrating the different roles that logic plays in the disciplines of computer science, mathematics, and philosophy, this consice undergraduate textbook covers select topics from three different areas of logic: proof theory, computability theory, and nonclassical theory. The book balances accessibility , breath, and rigor, and is designed so that its materials will fit into a single semester. Its distinctive presentation of traditional logic material will enhance readers' capabilities and mathematical maturity.
