ABSTRACT
There is something incongruous, possibly impertinent, in offering to give an inaugural lecture more than six years after this university had done me the signal honour of electing me to succeed so great a scholar as Sir Ernest Barker in the chair of Political Science. My main, my only effectual excuse, must be the stress and strain of war, the claims of other authorities than the university on what services I could perform. The alternative was not the giving of an inaugural lecture earlier but the not giving of it at all.
