Timothy Smiley has made ground-breaking contributions to modal logic, free logic, multiple-conclusion logic, and plural logic. He has illuminated Aristotles syllogistic, the ideas of logical form and consequence, and the distinction between assertion and rejection, and has worked to debunk the theory of descriptions. This volume brings together new articles by an international roster of leading logicians and philosophers in order to honour Smileys work. Their essays will be of significant interest to those working across the logical spectrumin philosophy of language, philosophical and mathematical logic, and philosophy of mathematics.
