TWO:Here we imagine an impatient reader exclaiming, ��How can Mr. Herbert Spencer, who knows, if possible, even less of Greek philosophy than of his own Unknowable, have derived that principle from the Greeks?�� Well, we have already traced the genealogy by which the two systems of agnosticism are connected. And some additional light will be thrown on the question if we consider that the form of Neo-Platonism was largely determined by the manner in which Plotinus brought the spiritualistic conceptualism of Plato and Aristotle into contact with the dynamic materialism of the Stoics; and that the form of Mr. Spencer��s philosophy has been similarly determined by bringing the idealism of modern German thought into contact with the mechanical evolutionism of modern science. Thus, under the influence of old associations, has pantheism been metamorphosed into a crude agnosticism, which faithfully reproduces the likeness of its original ancestors, the Plotinian Matter and the Plotinian One.The parentage of the two ideas will further elucidate their essentially heterogeneous character. For modern Communism is an outgrowth of the democratic tendencies which Plato detested; and as such had its counterpart in ancient Athens, if we may trust the Eccl��siazusae of Aristophanes, where also it is associated with unbridled licentiousness.155 Plato, on the261 contrary, seems to have received the first suggestion of his Communism from the Pythagorean and aristocratic confraternities of Southern Italy, where the principle that friends have all things in common was an accepted maxim.
