At a time when the debate is about the form that our allegiance to democracy should take, liberal or communitarian, republican or constitutional, it may be useful to go back to basics, to ask why we cherish democracy as it is. Our reasons could differ.
We need to start with Schumpeter. His innovation in contemporary Democratic Theory represented a breakthrough on two counts, both in theory construction, and in the nature of political explanation. I shall deal first with his contribution to theory, then with his implicit principles about how we should work as political scientists.
Schumpeter, as is well known, applied to the study of the political system the same paradigm that was used in the analysis of the market. The intuitive idea was that both systems were deemed to satisfy the interests (or preferences) of a given population. In the political system, preferences for programmes, or policies, corresponded to preferences for merchandise, and one could purchase them through the vote. On the other side, for those seeking election, offering programmes in exchange for votes brought profits in the form of political power.
