This established text book can be used to study and try out philosophical methods in practice. The third, completely revised edition contains eleven new articles, bringing the book in line with current courses: abduction, cluster definition, experimental philosophy, explication, context definition, criteria, methods, naturalistic fallacy, neologism, necessity and sufficiency set theory, and stipulative definition.
