Comparing and Miscomparing

I seek to explain the disappointing performance of the field of comparative politics addressing the three basic questions: Why compare? What is comparable? and How? I also challenge the view that the methodology of comparison is pretty well known and established. Hosts of unsettled issues remain, while a growing cause of frustration and failure is the undetected proliferation of `cat-dogs' (or worse), that is, nonexistent aggregates which are bound to defy, on account of their non-comparable characteristics, any and all attempts at law-like generalizations. The bottom line is that the comparative endeavor suffers from loss of purpose.
