We are still living under the reign of logic: this, of course, is what I have been driving at. But in this day and age logical methods are applicable only to solving problems of secondary interest. The absolute rationalism that is still in vogue allows us to consider only facts relating directly to our experience. Logical ends, on the contrary, escape us. It is pointless to add that experience itself has found itself increasingly circumscribed. It paces back and forth in a cage from which it is more and more difficult to make it emerge. It too leans for support on what is most immediately expedient, and it is protected by the sentinels of common sense.
