below (Phaedo) was a natural feeling which, in that age as well as in every other, has given distinctness to the hope of immortality. Nor were ethical considerations wanting, partly derived from the necessity of punishing the greater sort of criminals, whom no avenging power of this world could reach. The voice of conscience, too, was heard reminding the good man that he was not altogether innocent. (Republic.) To these indistinct longings and fears an expression was given in the mysteries and Orphic poets: a 'heap of books' (Republic), passing under the names of Musaeus and Orpheus in Plato's time, were filled with notions of an under-world. 16. Yet after all the belief in the individuality of the soul after death had but a feeble hold on the Greek mind. Like the personality of God, the personality of man in a future state was not inseparably bound up with the reality of his existence. For the distinction between the personal and impersonal, and also between the divine and human, was far less marked to the Greek than to ourselves. And as Plato readily passes from the notion of the good to that of God, he also passes almost imperceptibly to himself and his reader from the future life of the individual soul to the eternal being of the absolute soul. There has been a clearer statement and a clearer denial of the belief in modern times than is found in early Greek philosophy, and hence the comparative silence on the whole subject which is often remarked in ancient writers, and particularly in Aristotle. For Plato and Aristotle are not further removed in their teaching about the immortality of the soul than they are in their theory of knowledge.
