Now also Valentinus, the Coryphæus of those who herald community, in his book on _The Intercourse of Friends_, writes in these words: “Many of the things that are written, though in common books, are found written in the church of God. For those sayings which proceed from the heart are vain. For the law written in the heart is the People[994] of the Beloved--loved and loving Him.” For whether it be the Jewish writings or those of the philosophers that he calls “the Common Books,” he makes the truth common. And Isidore, at once son and disciple to Basilides, in the first book of the _Expositions of the Prophet Parchor_, writes also in these words: “The Attics say that certain things were intimated to Socrates, in consequence of a dæmon attending on him. And Aristotle says that all men are provided with dæmons, that attend on them during the time they are in the body,--having taken this piece of prophetic instruction and transferred it to his own books, without acknowledging whence he had abstracted this statement.” And again, in the second book of his work, he thus writes: “And let no one think that what we say is peculiar to the elect, was said before by any philosophers. For it is not a discovery of theirs. For having appropriated it from our prophets, they attributed it to him who is wise according to them.” Again, in the same: “For to me it appears that those who profess to philosophize, do so that they may learn what is the winged oak,[995] and the variegated robe on it,” all of which Pherecydes has employed as theological allegories, having taken them from the prophecy of Cham. CHAPTER VII. WHAT TRUE PHILOSOPHY IS, AND WHENCE SO CALLED. As we have long ago pointed out, what we propose as our subject is not the discipline which obtains in each sect, but that which is really philosophy, strictly systematic Wisdom, which furnishes acquaintance with the things which pertain to life. And we define Wisdom to be certain knowledge, being a sure and irrefragable apprehension of things divine and human, comprehending the present, past, and future, which the Lord hath taught us, both by His advent and by the prophets. And it is irrefragable by reason, inasmuch as it has been communicated. And so it is wholly true according to [God’s] intention, as being known through means of the Son. And in one aspect it is eternal, and in another it becomes useful in time. Partly it is one and the same, partly many and indifferent--partly without any movement of passion, partly with passionate desire--partly perfect, partly incomplete. This wisdom, then--rectitude of soul and of reason, and purity of life--is the object of the desire of philosophy, which is kindly and lovingly disposed towards wisdom, and does everything to attain it.
