Abstract
James Harrington e la concezione del "commonweath" come organismo - This article aims to shed light on the link between Harrington’s political thought and his conception of Nature as an organic whole. Such a relation is reflected in the way mixed government and the representative system are designed to act as complementary institutions of a republic or commonwealth. Under mixed government, the popular balance of property - a political transposition of the fullness of natural life meaning the spread of landed property among the population - is tempered by a quarter of the entire territory being concentrated in the hands of a minority of big landowners. On this basis, the minority ensures for its members exclusive access to the Senate, as an aristocratic institution. In the context of the representative system, the fact that the Senate alone can deliberate, whereas a Popular Assembly can only accept or reject decisions made by the Senate, is moderated by periodical elections of both Houses of Parliament based on popular suffrage
