XLI. (136) "But Rebekkah," says Moses, "went down to the fountain to fill her pitcher, and came up again." For from what source is it natural for the mind that thirsts after wisdom to be filled, except from the wisdom of God, that fountain which never fails, and to which the soul that descends comes up again like a virtuous disciple? For those who descend out of a vain pride, the reason of virtue receives, and taking them up by means of fame raises them to a height. On which account it is that Moses seems to me to use the expression, "Go, descend, and come Up,"[Ex 32:7.] as if every one who measures his own loveliness comes forth more gloriously in the eyes of the judges of truth. And he speaks of these matters with great caution. (137) For Agar bears a leathern bag to the well, but Rebekkah carries a pitcher. For the one who devotes himself to instruction and to the energetical branches of learning has need of some incorporeal things as it were of the outward senses, of vessels, and eyes, and ears, for a proper contemplation of the objects of her speculation. For from seeing many things and hearing many things, there is derived, in the case of those who are fond of learning the advantage which proceeds from knowledge. But the one who is filled with unalloyed wisdom has need only of a leathern habitation, which is no better than none at all. For the soul which loves unsubstantial things has learnt to put off the whole leathern bag of reasons, that is to say the body, and brings only a pitcher which is the symbol of a vessel, which contains the principal portion in great size and abundance, like water; as to which, those who are clever in such matters may make it a subject of philosophical speculation, whether it is a membrane or a heart. (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.
