Abstract
In any generation there are relatively few people who make major original contributions to even a single area of philosophy. But the man whose work is the topic of this conference has made such contributions not only in a single field, but in several. This morning and afternoon we have devoted our attention to Chisholm's epistemology, the breadth and significance of which is evident. Equally deserving of our attention, however, are his contributions to the theory of action and metaphysics, and we shall be turning to these topics this evening and tomorrow. As in epistemology, Chisholm's work in these areas has focused on the deepest philosophical problems. He has worked out suggested solutions to these problems with a scope, precision, and care which serve as models for others to emulate.
