Chapter XX.
Of the nature of gluttony, which may be illustrated by the simile of the eagle.
An admirable illustration of this passion, with which a monk, however spiritual and excellent, is sure to be hampered, is found in the simile of the eagle. For this bird when in its flight on high it has soared above the highest clouds, and has withdrawn itself from the eyes of all mortals and from the face of the whole earth, is yet compelled by the needs of the belly to drop down and descend to the earth and feed upon carrion and dead bodies. And this clearly shows that the spirit of gluttony cannot be altogether extirpated like all other faults, nor be entirely destroyed like them, but that we can only hold down and check by the power of the mind all incentives to it and all superfluous appetites.
Chapter XXI.
Of the lasting character of gluttony as described to some philosophers.
For the nature of this fault was admirably expressed under cover of the following puzzle by one of the Elders in a discussion with some philosophers, who thought that they might chaff him like a country bumpkin because of his Christian simplicity. "My father," said he, "left me in the clutches of a great many creditors. All the others I have paid in full, and have freed myself from all their pressing claims; but one I cannot satisfy even by a daily payment." And when they could not see the meaning of the puzzle, and urgently begged him to explain it: "I was," said he, "in my natural condition, encompassed by a great many faults. But when God inspired me with the longing to be free, I renounced this world, and at the same time gave up all my property which I had inherited from my father, and so I satisfied them all like pressing creditors, and freed myself entirely from them. But I was never able altogether to get rid of the incentives to gluttony. For though I reduce the quantity of food which I take to the smallest possible amount, yet I cannot avoid the force of its daily solicitations, but must be perpetually dunned' by it, and be making as it were interminable payments by continually satisfying it, and pay never ending toll at its demand." Then they declared that this man, whom they had till now despised as a booby and a country bumpkin, had thoroughly grasped the first principles of philosophy, i.e., training in ethics, and they marvelled that he could by the light of nature have learnt that which no schooling in this world could have taught him, while they themselves with all their efforts and long course of training had not learnt this. This is enough on gluttony in particular. Now let us return to the discourse in which we had begun to consider the general relation of our faults to each other.
Chapter XXII.
How it was that God foretold to Abraham that Israel would have to drive out ten nations.
When the Lord was speaking with Abraham about the future (a point which you did not ask about) we find that He did not enumerate seven nations, but ten, whose land He promised to give to his seed. [1356] And this number is plainly made up by adding idolatry, and blasphemy, to whose dominion, before the knowledge of God and the grace of Baptism, both the irreligious hosts of the Gentiles and blasphemous ones of the Jews were subject, while they dwelt in a spiritual Egypt. But when a man has made his renunciation and come forth from thence, and having by God's grace conquered gluttony, has come into the spiritual wilderness, then he is free from the attacks of these three, and will only have to wage war against those seven which Moses enumerates.

Chapter XXIII.
How it is useful for us to take possession of their lands.
But the fact that we are bidden for our good to take possession of the countries of those most wicked nations, may be understood in this way. Each fault has its own especial corner in the heart, which it claims for itself in the recesses of the soul, and drives out Israel, i.e., the contemplation of holy and heavenly things, and never ceases to oppose them. For virtues cannot possibly live side by side with faults. "For what participation hath righteousness with unrighteousness? Or what fellowship hath light with darkness?" [1357] But as soon as these faults have been overcome by the people of Israel, i.e., by those virtues which war against them, then at once the place in our heart which the spirit of concupiscence and fornication had occupied, will be filled by chastity. That which wrath had held, will be claimed by patience. That which had been occupied by a sorrow that worketh death, will be taken by a godly sorrow and one full of joy. That which had been wasted by accidie, will at once be tilled by courage. That which pride had trodden down will be ennobled by humility: and so when each of these faults has been expelled, their places (that is the tendency towards them) will be filled by the opposite virtues which are aptly termed the children of Israel, that is, of the soul that seeth God: [1358] and when these have expelled all passions from the heart we may believe that they have recovered their own possessions rather than invaded those of others.
