[138] Therefore, the man who is fond of learning, seeing men imbibing the sciences like water, from wisdom that divine fountain, runs up, and meeting them becomes a suppliant to them to know how he may allay his thirst for learning. And the soul which has received the best possible education, namely, the lesson not to envy, and to be liberal, immediately proffers to him the stream of wisdom, and invites him to drink abundantly, adding also this that she calls him who is only a servant her lord. This is the meaning of that most dogmatic assertion, that the wise man alone is free, and a king, even if he have ten thousand masters over his body.
