Seeing, therefore, that the Platonists held opinions which they could not impart to men enthralled by the flesh; seeing also that they were not of such authority among the common people as to persuade them to accept what they ought to believe until the mind should be trained to that condition in which these things can be understood,--they chose to hide their own opinions, and to content themselves with arguing against those who, although they affirmed that the discovery of truth is made through the senses of the body, boasted that they had found the truth. And truly, what occasion have we to inquire as to the nature of their teaching? We know that it was not divine, nor invested with any divine authority. But this one fact merits our attention, that whereas Plato is in many ways most clearly proved by Cicero to have placed both the supreme good and the causes of things, and the certainty of the processes of reason, in Wisdom, not human, but divine, whence in some way the light of human wisdom is derived--in Wisdom which is wholly immutable, and in Truth always consistent with itself; and whereas we also learn from Cicero that the followers of Plato laboured to overthrow the philosophers known as Epicureans and Stoics, who placed the supreme good, the causes of things, and the certainty of the processes of reason, in the nature either of body or of mind,--the controversy had continued rolling on with successive centuries, so that even at the commencement of the Christian era, when the faith of things invisible and eternal was with saving power preached by means of visible miracles to men, who could neither see nor imagine anything beyond things material, these same Epicureans and Stoics are found in the Acts of the Apostles to have opposed themselves to the blessed Apostle Paul, who was beginning to scatter the seeds of that faith among the Gentiles.
