pilgrimage of polymathism

Disciplines, like nations, are a necessary evil that enable human beings of bounded rationality to simplify their goals and reduce their choices to calculable limits. But parochialism is everywhere, and the world badly needs international and interdisciplinary travelers to carry knowledge from one enclave to another. Having spent much of my scientific life in such travel, I can offer one piece of advice to others who wish to try an itinerant existence: It is fatal to be regarded as a good economist by psychologists, and a good psychologist by political scientists. Immediately upon landing on alien shores, you must begin to acquire the local culture, not to deny your origins but to gain the full respect of the natives. When in economics, there is no substitute for talking the language of marginal analysis and regressions -- even (or especially) when your purpose is to demonstrate their limitations. When in psychology, you must be able to understand references to short-term memory and latencies and spreading activation. The task is not onerous; after all, we acculturize new graduate students in a couple of years. Besides, it may lead you to write papers on fascinating  topics that you would otherwise never have encountered. For one of the nice features of the utility function (or the committee of goals I would substitute for it) is that it can acquire ever new dimensions. Learning a new language every decade or so is a great immunizer against incipient boredom

On the day they are ordered to war Soldiers may sit and weep Or lie down in quiet misery But once plunged into battle With no way out but forward They will fight as bravely As the bravest warriors of old.
