Discourses: Book 1 1 : 1

Among the arts and faculties in general you will find none that is self-contemplative, and therefore none that is either self-approving or self-disapproving. How far does the art of grammar possess the power of contemplation? Only so far as to pass judgement upon what is written. How far the art of music? Only so far as to pass judgement upon the melody. Does either of them, then, contemplate itself? Not at all. But if you are writing to a friend and are at a loss as to what to write, the art of grammar will tell you; yet whether or no you are to write to your friend at all, the art of grammar will not tell. The same holds true of the art of music with regard to melodies; but whether you are at this moment to sing and play on the lyre, or neither sing nor play, it will not tell. What art or faculty, then, will tell? That one which contemplates both itself and everything else. And what is this? The reasoning faculty; for this is the only one we have inherited which will take knowledge both of itself—what it is, and of what it is capable, and how valuable a gift it is to us—and likewise of all the other faculties. For what else is it that tells us gold is beautiful? For the gold itself does not tell us. Clearly it is the faculty which makes use of external impressions. What else judges with discernment the art of music, the art of grammar, the other arts and faculties, passing judgement upon their uses and pointing out the seasonable occasions for their use? Nothing else does.
