took of Plotinus' theory of the Idea. This latter was in the form of a reply to Basileus of Tyre, my friend as theirs. He had preferred Plotinus' system to mine and had written several works in the manner of his master, amongst them a treatise supporting Plotinus' theory of the Idea against that which I taught. I endeavoured, not, I think, unsuccessfully, to show that his change of mind was mistaken.
In these two essays I have ranged widely over the doctrines of this school, as also in my Letter to Amelius which, despite the simple title with which I contented myself, has the dimensions of a book, being a reply to a treatise he addressed to me from Rome under the title "On Plotinus’ Philosophic Method."

This Preface leaves no doubt of Longinus' final verdict: he ranks Plotinus and Amelius above all authors of his time in the multitude of questions they discuss; he credits them with an original method of investigation: in his judgement they by no means took their system from Numenius or gave a first place to his opinions, but followed the Pythagorean and Platonic schools; finally he declares the writings of Numenius, Cronius, Moderatus and Thrasyllus greatly inferior in precision and fulness to those of Plotinus.
Notice, by the way, that while Amelius is described as following in Plotinus' footsteps, it is indicated that his temperamental prolixity led him to delight in an extravagance of explanation foreign to his master: in the reference to myself, though I was then only at the beginning of my association with Plotinus "Basileus of Tyre, my friend as theirs, who has written a good deal, has taken Plotinus as his model"—Longinus recognises that I entirely avoided Amelius' unphilosophical prolixity and made Plotinus' manner my standard.
Such a pronouncement upon the value of Plotinus' work, coming from so great an authority, the first of critics then as now, must certainly carry weight, and I may remark that if I had been able to confer with him, during such a visit as he proposed, he would not have written to combat doctrines which he had not thoroughly penetrated.
