A very slight reading of Clement of Alexandria is enough to prove how deeply he is indebted to Plato both in respect of language and of thought. Quotations from Plato are to be found throughout Clement's works, and in many cases acknowledgment is made of their origin. In addition there are frequent allusions, which for the most part the student of Plato can easily recognize. Clement invariably shows a profound respect for the Greek philosopher, whom he looks upon as a seeker after truth and as an authority, we may almost say, second only to the Scriptures. A careful comparison of the Protrepticus with the Phaedrus, results of which are given below, will furnish a striking illustration of the close dependence of Clement upon Plato. The Protrepticus is a short work, occupying in space not more than one–twelfth of Clement's extant writings, while the Phaedrus is even smaller in proportion to the whole of Plato. It is remarkable that so much inter-connexion should be found in so small a field, especially when we remember that the references to the Phaedrus represent by no means the whole of Clement's drawing upon Plato in the Protrepticus. There are allusions also to the Theaetetus, Republic, Charmides, Laws and Epistles, and possibly to the Politicus, Cratylus, Philebus, Symposium and Apology.
