Since the degree of affection a thing deserves depends upon the degree of its value, and the previous chapter shows that the value of books is unspeakable, it is quite clear to the reader what is the probable conclusion from this. I say probable, for in moral science we do not insist upon demonstration, remembering that the educated man seeks such degree of certainty as he perceives the subject-matter will bear, as Aristotle testifies in the first book of his Ethics. For Tully does not appeal to Euclid, nor does Euclid rely upon Tully. This at all events we endeavour to prove, whether by logic or rhetoric, that all riches and all delights whatsoever yield place to books in the spiritual mind, wherein the Spirit which is charity ordereth charity. Now in the first place, because wisdom is contained in books more than all mortals understand, and wisdom thinks lightly of riches, as the foregoing chapter declares. Furthermore, Aristotle, in his Problems, determines the question, why the ancients proposed prizes to the stronger in gymnastic and corporeal contests, but never awarded any prize for wisdom. This question he solves as follows: In gymnastic exercises the prize is better and more desirable than that for which it is bestowed; but it is certain that nothing is better than wisdom: wherefore no prize could be assigned for wisdom. And therefore neither riches nor delights are more excellent than wisdom. Again, only the fool will deny that friendship is to be preferred to riches, since the wisest of men testifies this; but the chief of philosophers honours truth before friendship, and the truthful Zorobabel prefers it to all things. Riches, then, are less than truth. Now truth is chiefly maintained and contained in holy books--nay, they are written truth itself, since by books we do not now mean the materials of which they are made. Wherefore riches are less than books, especially as the most precious of all riches are friends, as Boethius testifies in the second book of his Consolation; to whom the truth of books according to Aristotle is to be preferred. Moreover, since we know that riches first and chiefly appertain to the support of the body only, while the virtue of books is the perfection of reason, which is properly speaking the happiness of man, it appears that books to the man who uses his reason are dearer than riches. Furthermore, that by which the faith is more easily defended, more widely spread, more clearly preached, ought to be more desirable to the faithful. But this is the truth written in books, which our Saviour plainly showed, when he was about to contend stoutly against the Tempter, girding himself with the shield of truth and indeed of written truth, declaring "it is written" of what he was about to utter with his voice.
