The explosive progress of logic, since Frege, has produced applications
in linguistics, mathematics and computer science. Students and
practitioners of any of these fields, and of philosophy, will find this
book an excellent reference or introduction. Now expanded to include
non-classical logic, logic for the computer, and more. The central
concepts are explained as they come into play in informal writing and
conversation--argument, validity, relevance, and so on. This study
guide progresses to concepts such as probability calculus.
