Abstract

Many of the papers in this volume originated in a colloquium at the University of Western Ontario in 1967. These include a paper on the logic of norms by G. H. Von Wright, a paper on the logic of questions by L. Åqvist, a paper on the logic of belief by W. Sellars, and a paper on inductive logic by R. Ackermann. The commentaries by Anderson and Sosa have been revised for the volume and a further commentary to Ackermann's paper by Wesley Salmon has been added. In addition to the colloquium papers a number of further papers are published here for the first time: J. Hintikka on the semantics of propositional attitudes, R. Hilpinen on relativized modalities, C. Harrison on the unanticipated examiner and H. Smokler and M. Rohr on confirmation and translation. The volume is completed by two papers published in Synthese and a well-known paper in modal logic by Lemmon, Meredith, Meredith, Prior, and Thomas published complete with a new postscript by Prior. Although the collection is somewhat haphazard and seems to have no unifying theme, philosophers interested in these topics in philosophical logic will be thankful for the availability of the papers, both old and new.--R.
