"The later Morishima’s dissatisfaction with the false sense of completed achievement―and the related smugness―of many pure theorists did make sense, and he was right to emphasize the need to seek constantly a fuller picture which could do justice to the reality around us, rather than seeing their separated investigations as the end of their task. All the constructive insights that the later Morishima offers become relevant when that exercise of broadening is undertaken. And yet, this does not require us to dismiss the nature of the contribution that the early Morishima made, or discard the contributions that old-fashioned economic theory has made and still makes to our understanding of the world. In defence of the latter claim, I offer the fact that even the highly oversimplified General Theory of Employment, Interest and Money of that great abstractionist, John Maynard Keynes (1936), made a significant difference to public policy. I could refer also to the fact that, when Michio was trying to expand the education of the Archbishop of Canterbury, he had no hesitation in bringing in some results of fairly pure Marxian economic theory to the attention of a person with a very powerful voice in the real world; and Robert Runcie himself appreciated this fully. The relation between useful abstraction and underlying reality requires, I would argue, an enduringly dual approach."
