From which it is seen clearly enough, that as laws are neither arts nor sciences, so books of law cannot properly be called books of art or science. Nor is this faculty which we may call by a special term geologia, or the earthly science, to be properly numbered among the sciences. Now the books of the liberal arts are so useful to the divine writings, that without their aid the intellect would vainly aspire to understand them. CHAPTER XII WHY WE HAVE CAUSED BOOKS OF GRAMMAR TO BE SO DILIGENTLY PREPARED While we were constantly delighting ourselves with the reading of books, which it was our custom to read or have read to us every day, we noticed plainly how much the defective knowledge even of a single word hinders the understanding, as the meaning of no sentence can be apprehended, if any part of it be not understood. Wherefore we ordered the meanings of foreign words to be noted with particular care, and studied the orthography, prosody, etymology, and syntax in ancient grammarians with unrelaxing carefulness, and took pains to elucidate terms that had grown too obscure by age with suitable explanations, in order to make a smooth path for our students. This is the whole reason why we took care to replace the antiquated volumes of the grammarians by improved codices, that we might make royal roads, by which our scholars in time to come might attain without stumbling to any science. CHAPTER XIII WHY WE HAVE NOT WHOLLY NEGLECTED THE FABLES OF THE POETS All the varieties of attack directed against the poets by the lovers of naked truth may be repelled by a two-fold defence: either that even in an unseemly subject-matter we may learn a charming fashion of speech, or that where a fictitious but becoming subject is handled, natural or historical truth is pursued under the guise of allegorical fiction.
