Plato's First Alcibiades was the recognised introduction to the dialogues of Plato in late antiquity, because it addresses the important question of the nature of the self. Only by discovering this can we understand the perspective from which we view the rest of reality. It was also considered as a necessary first step in our pursuit of happiness, for unless we know what we are we cannot know what will bring about our fulfilment - and without the fulfilment of our true nature we cannot be happy. As a key to human understanding and happiness, the dialogue is as important today as it was in antiquity. Approximate Stephanus pagination accompanies the text. Added to this dialogue, in the form of additional notes and an introduction, is much of Proclus' Commentary written on the understanding that "it will be found by those who are deeply skilled in the philosophy of Plato, that each of his dialogues contains that which the universe contains." The Commentary reveals to the thoughtful student the depths of this important dialogue, its universal form, and its living heart - which is the quickening of the soul by the touch of divine vision. Three modern essays, written with the newcomer in mind, accompany the text and commentary: A Survey of the Soul and Socrates as the Symbolic Daemon of the Alcibiades by Tim Addey, and Possibilities of Self by Guy Wyndham-Jones.
