1. Theknowledge of things terrestrial and celestial is commonly thought much of by men. Yet those doubtless judge better who prefer to that knowledge, the knowledge of themselves; and that mind is more praiseworthy which knows even its own weakness, than that which, without regard to this, searches out, and even comes to know, the ways of the stars, or which holds fast such knowledge already acquired, while ignorant of the way by which itself to enter into its own proper health and strength. But if any one has already become awake towards God, kindled by the warmth of the Holy Spirit, and in the love of God has become vile in his own eyes; and through wishing, yet not having strength to come in unto Him, and through the light He gives, has given heed to himself, and has found himself, and has learned that his own filthiness cannot mingle with His purity; and feels it sweet to weep and to entreat Him, that again and again He will have compassion, until he have put off all his wretchedness; and to pray confidently, as having already received of free gift the pledge of salvation through his only Saviour and Enlightener of man:—such an one, so acting, and so lamenting, knowledge does not puff up, because charity edifieth; 438 for he has preferred knowledge to knowledge, he has preferred to know his own weakness, rather than to know the walls of the world, the foundations of the earth, and the pinnacles of heaven. And by obtaining this knowledge, he has obtained also sorrow; 439 but sorrow for straying away from the desire of reaching his own proper country, and the Creator of it, his own blessed God. And if among men such as these, in the family of Thy Christ, O Lord my God, I groan among Thy poor, give me out of Thy bread to answer men who do not hunger and thirst after righteousness, but are sated and abound. 440 But it is the vain image of those things that has sated them, not Thy truth, which they have repelled and shrunk from, and so fall into their own vanity. I certainly know how many figments the human heart gives birth to. And what is my own heart but a human heart? But I p. 70 pray the God of my heart, that I may not vomit forth (eructuem) into these writings any of these figments for solid truths, but that there may pass into them only what the breath of His truth has breathed into me; cast out though I am from the sight of His eyes, 441 and striving from afar to return by the way which the divinity of His only-begotten Son has made by His humanity. And this truth, changeable though I am, I so far drink in, as far as in it I see nothing changeable: neither in place and time, as is the case with bodies; nor in time alone, and in a certain sense place, as with the thoughts of our own spirits; nor in time alone, and not even in any semblance of place, as with some of the reasonings of our own minds. For the essence of God, whereby He is, has altogether nothing changeable, neither in eternity, nor in truth, nor in will; since there truth is eternal, love eternal; and there love is true, eternity true; and there eternity is loved, and truth is loved.
