I would address one general admonition to all, that they consider what are the true ends of knowledge, and that they seek it not either for pleasure of the mind, or for contention, or for superiority to others, or for profit, or for fame, or power, or any of these inferior things, but for the benefit and use of life; and that they perfect and govern it in charity. For it was from lust of power that the Angels fell, from lust of knowledge that man fell, but of charity there can be no excess, neither did angel or man come in danger by it.
