It is a long time since I have attended a gathering of the scientific world - a world in which I am at home - one in which men deal with realities and where truth is, in fact, the goal. For the past ten years I have been in exile from this world and an explorer in another - a world where men substitute words for realities and then talk about the words. Truth in that world seems merely to be the avowed object. Now I undertook to reconcile the objects of these two worlds and for a time I believed that could be accomplished. Perhaps I still believe it - or perhaps it is all a dream.
