ABSTRACT
In the day economic science (entirely superseding political science) has become the statesman's guide to popular welfare. If the limitations of economic science are a condition of its rigor, an invitation to enlarge its scope may imply some contradiction. Such enlargement is however inevitable in view of the fact that increasing power and speed and achievement urgently call for some advisory science, and economics is chosen to perform that function. For this purpose, political economy may well stretch to political ecology, that is, the "flows" which the economist is wont to consider will be regarded as "derivations" applied to the mighty "flows" of natural processes. The fact that Antipho enters the picture while Socrates does not becomes of great importance when the picture drawn by the economists serves as a guide for policy. The complaint is that free services are omitted by reason of their gratuity, which tends to bias the picture of society.
