To this man, therefore, should we undertake to return thanks adequate to the benefits which we have received from him; the whole of time would not be sufficient. But if it is necessary, not only[84] that we should have received from others the transcendant good of the Platonic philosophy, but that we should leave to posterity monuments of those blessed spectacles of which we have been spectators, and emulators to the utmost of our ability, under a leader the most perfect of the present time, and who arrived at the summit of philosophy; perhaps we shall act properly in invoking the gods, that they will enkindle the light of truth in our soul, and in supplicating the attendants and ministers of better natures to direct our intellect and lead it to the all-perfect, divine, and elevated, end of the Platonic theory. For I think that every where he who participates in the least degree of intelligence, will begin his undertakings from the Gods, and especially in explications respecting the Gods: for we can no otherwise be able to understand a divine nature than by being perfected through the light of the Gods; nor divulge it to others unless governed by them, and exempt from multiform opinions, and the variety which subsists in words, preserving at the same time the interpretation of divine names. Knowing therefore this, and complying with the exhortation of the Platonic Timæus, we in the first place establish the Gods as leaders of the doctrine respecting themselves. But may they in consequence of hearing our prayers be propitious to us, and benignantly approaching, guide the intellect of our soul, and lead it about the Vesta of Plato, and to the arduous sublimities of this speculation; where, when arrived, we shall receive all the truth concerning them, and shall obtain the best end of our parturient conceptions of divine concerns, desiring to know something respecting them, inquiring about them of others, and, at the same time, as far as we are able, exploring them ourselves. CHAPTER II. And thus much by way of preface. But it is necessary that I should unfold the mode of the proposed doctrine, what it is requisite to expect it will be, and define the preparatives which a hearer of it ought to possess; that being properly adapted, he may approach, not to our discourses, but to the intellectually-elevated and deific philosophy of Plato. For it is proper that convenient aptitudes of auditors should be proposed according to the forms of discourses, just as in the mysteries, those who are skilful in concerns of this kind, previously prepare receptacles for the Gods, and neither always use the same inanimate particulars, nor other animals, nor men, in order to procure the presence of the divinities; but that alone out of each of these which is naturally capable of participating divine illumination, is by them introduced to the proposed mystic rites.
