It is a useful fact that you wish to know, one which is essential to him who hastens after wisdom—namely, the parts of philosophy and the division of its huge bulk into separate members. For by studying the parts we can be brought more easily to understand the whole. I only wish that philosophy might come before our eyes in all her unity, just as the whole expanse of the firmament is spread out for us to gaze upon! It would be a sight closely resembling that of the firmament. For then surely philosophy would ravish all mortals with love for her; we should abandon all those things which, in our ignorance of what is great, we believe to be great. Inasmuch, however, as this cannot fall to our lot, we must view philosophy just as men gaze upon the secrets of the firmament.

The wise man’s mind, to be sure, embraces the whole framework of philosophy, surveying it with no less rapid glance than our mortal eyes survey the heavens; we, however, who must break through the gloom, we whose vision fails even for that which is near at hand, can be shown with greater ease each separate object even though we cannot yet comprehend the universe. I shall therefore comply with your demand, and shall divide philosophy into parts, but not into scraps. For it is useful that philosophy should be divided, but not chopped into bits. Just as it is hard to take in what is indefinitely large, so it is hard to take in what is indefinitely small. 3. The people are divided into tribes, the army into centuries. Whatever has grown to greater size is more easily identified if it is broken up into parts; but the parts, as I have remarked, must not be countless in number and diminutive in size. For over-analysis is faulty in precisely the same way as no analysis at all; whatever you cut so fine that it becomes dust is as good as blended into a mass again.

In the first place, therefore, if you approve, I shall draw the distinction between wisdom and philosophy. Wisdom is the perfect good of the human mind; philosophy is the love of wisdom, and the endeavour to attain it. The latter strives toward the goal which the former has already reached. And it is clear why philosophy was so called. For it acknowledges by its very name the object of its love. 5. Certain persons have defined wisdom as the knowledge of things divine and things human. Still others say: “Wisdom is knowing things divine and things human, and their causes also.” This added phrase seems to me to be superfluous, since the causes of things divine and things human are a part of the divine system. Philosophy also has been defined in various ways; some have called it “the study of virtue,” others have referred to it as “a study of the way to amend the mind,” and some have named it “the search for right reason.” 6. One thing is practically settled, that there is some difference between philosophy and wisdom. Nor indeed is it possible that that which is sought and that which seeks are identical. As there is a great difference between avarice and wealth, the one being the subject of the craving and the other its object, so between philosophy and wisdom. For the one is a result and a reward of the other. Philosophy does the going, and wisdom is the goal. 7. Wisdom is that which the Greeks call σοφία. The Romans also were wont to use this word in the sense in which they now use “philosophy” also. This will be proved to your satisfaction by our old national plays, as well as by the epitaph that is carved on the tomb of Dossennus:

Pause, stranger, and read the wisdom of Dossennus.

8. Certain of our school, however, although philosophy meant to them “the study of virtue,” and though virtue was the object sought and philosophy the seeker, have maintained nevertheless that the two cannot be sundered. For philosophy cannot exist without virtue, nor virtue without philosophy. Philosophy is the study of virtue, by means, however, of virtue itself; but neither can virtue exist without the study of itself, nor can the study of virtue exist without virtue itself. For it is not like trying to hit a target at long range, where the shooter and the object to be shot at are in different places. Nor, as roads which lead into a city, are the approaches to virtue situated outside virtue herself; the path by which one reaches virtue leads by way of virtue herself; philosophy and virtue cling closely together.
