Excerpt from the book:
"Having surveyed the theories of our six political philosophers, it is fitting and proper that we should inquire whether there has been in fact a close relation between the structure of the state and the economic composition of society. It would be interesting, if time permitted, to examine the constitution of Athens and to consider such matters as Draco's legislation and Solon's reforms or to analyse the illuminating pages in which Polybius describes the balance of powers in Rome. The results of such a study, pondered in connection with the theories we have just reviewed, could not fail to set in train a fascinating line of speculation. There are, however, limits to this undertaking, and we must confine our scrutiny to the modern state in its historical growth."
