For a complete list of scholars who have devoted more or less attention to the economic ideas of Greek thinkers, the reader is referred to the bibliography at the conclusion of this work. On the surface, the list appears to be reasonably extensive. It will be observed, however, that the majority of the works are not of recent date; that many of them deal largely with the practical phase of economics; that most of the larger works on economic history treat Greek economic and social theory in a merely incidental manner, and that nearly all are written from the general standpoint of the economist rather than with the more detailed analysis of the classicist. The work of Souchon, the most extensive, careful, and satisfactory discussion of the subject, is no exception to this latter rule, and since his standpoint is too exclusively that of the older English economists, his criticism of the Greek theories is not always sufficiently sympathetic. The monumental volumes of Poehlmann have treated Greek social theories thoroughly, but the chief interest of the author is rather in the actual social conditions, and his work is marred by a constant overemphasis of the analogy between ancient and modern capitalism and socialistic agitation. Moreover, there is no book in the English language, on Greek economic thought, that treats the subject in anything more than the cursory manner of Haney and Ingram.[1] There is, thus, still a place for a work of this type in the English language, written from the standpoint of the classicist, but with a view also to the needs of twentieth-century students of economics. The present work aims to fulfil such a need. Its scope differs quite essentially from all other accounts of Greek theory previously published, in that our purpose is not merely to consider the extent to which the Greek thinkers grasped the principles of the orthodox economy of Ricardo and Mill. We shall also endeavor to ascertain how far they, by the humanitarian and ethical tone of their thinking, anticipated the modern, post-Ruskin economy, which makes man, not property, the supreme goal, and recognizes the multiplicity of human interests and strivings that belie the old theory of the “economic man.” Our verdict as to the importance of the Greek contribution to economic thought is thus likely to be somewhat more favorable than that which is usually rendered. We purpose also to emphasize more than is often done the important fact that Greek theory is essentially a reflection of Greek economic conditions, and that a true interpretation of the thought depends upon a clear understanding of the economic history of Greece. However, as we shall see, this by no means implies that the anti-capitalistic theories of the Socratics are evidence of an undeveloped state of commerce and industry in fifth- and fourth-century Athens.
