The Discourses of Epictetus: Book I: Chapter I. On Things in Our Power and Things Not in Our Power

BOOK I CHAPTER I ON THINGS IN OUR POWER AND THINGS NOT IN OUR POWER Of our faculties in general you will find that none can take cognizance of itself; none therefore has the power to approve or disapprove its own action. Our grammatical faculty for instance: how far can that take cognizance? Only so far as to distinguish expression. Our musical faculty? Only so far as to distinguish tune. Does any one of these then take cognizance of itself? By no means. If you are writing to your friend, when you want to know what words to write grammar will tell you; but whether you should write to your friend or should not write grammar will not tell you. And in the same way music will tell you about tunes, but whether at this precise moment you should sing and play the lyre or should not sing nor play the lyre it will not tell you. What will tell you then? That faculty which takes cognizance of itself and of all things else. What is this? The reasoning faculty: for this alone of the faculties we have received is created to comprehend even its own nature; that is to say, what it is and what it can do, and with what precious qualities it has come to us, and to comprehend all other faculties as well. For what else is it that tells us that gold is a goodly thing? For the gold does not tell us. Clearly it is the faculty which can deal with our impressions. 1-1 What else is it which distinguishes the faculties of music, grammar, and the rest, testing their uses and pointing out the due seasons for their use? It is reason and nothing else.
