This volume features work on learning by researchers in various disciplines who share an interest in the systematic study of cognition and in the study of the formal and semantic aspects of language acquisition. A recurring theme is that language learning involves the acquisition of certain competencies and the formation of a system of beliefs which are significantly underdetermined by the linguistic and nonlinguistic inputs available to the learner. Theories of language learning must confront the epistemological problem of how it is possible to induce and fixate a belief-system on the basis of exposure to limited data. A typical strategy in dealing with this problem has been to specify various types of formal and empirical constraints on linguistic and conceptual development in terms of specific hypotheses about the character of what is learned and about the kinds of resources and strategies available to the learner. Most of the contributions in this volume are concerned with the specification and evaluation of such constraints.

This volume contains the papers and commentaries presented at the fourth philosophy colloquium at the University of Western Ontario in November 1968. The papers examine, from different points of view, the central problems in the philosophy of action. They include: “Agency” by Donald Davidson with comments by James Cornman; “On the Logic on International Action” by Roderick Chisholm with comments by Bruce Aune and a reply by Roderick Chisholm; “Wanting: Some Pitfalls” by R.M. Hare with comments by David Gauthier and D.F. Pears; “Two Problems about Reasons for Actions” by D.F. Pears with comments by Irving Thalberg. Also included is an extensive bibliography of recent work in the philosophy of action. The contributors are all well known for their work in this branch of philosophy; their papers present a cross section of the best work being done in the area at the present time.
