Abstract

But in attempting to follow some of the steps of Mr. Barber's later argument, and in examining some of the conclusions to which they lead, I have found myself confronted with difficulties which seem sufficiently important to warrant the critical attention of Mr. Barber and the readers of this Review. These difficulties fall into three groups concerning: 1) preliminary arguments; 2) apparent inconsistencies between certain conclusions; and 3) inadequacies in basic ontology.
