ABSTRACT
Speaking from a newly founded Chair, I find myself freed from one embarrassment only to fall into another. I have no great predecessors to overshadow me; on the other hand, I must try (as the theatrical people say) 'to create the part'. The responsibility is heavy. If I miscarry, the University might come to regret not only my election-an error which, at worst, can be left to the great healer-but even, which matters very much more, the foundation of the Chair itself. That is why I have thought it best to take the bull by the horns and devote this lecture to explaining as clearly as I can the way in which I approach my work; my interpretation of the commission you have given me.
