The advantage of simple Knowledge can be seen in the case of the husbandman.

It is right, therefore, that we should investigate well the advantage of things by an examination of them ; and if they are [x]  judged by the investigators to be simple, there are many things which are thought to be obviously unsuccessful, but their unseen qualities achieve a great victory. For there is nothing that appears more simple than this, that the husbandman should take and scatter in the earth the gathered seeds which he holds in his hands. But, after a time, when it is seen that the scattered seed has been gathered and has come with a multitude like a general with his army, and that the seed which had been regarded as lost is found and finds also other (seeds) with it, then a man marvels at the husbandman's simplicity, which has become a fountain of cleverness. Therefore, with regard to this very thing, hear on the other hand the opposite of it, that if a man spare the gathered seed, so as not to scatter it, he is thought indeed to act prudently in refraining from scattering. But when we see the husbandman's scattered investment collected in the principal and interest, and the earth rewarding him, then the intelligence which refrained from scattering is seen to be [Ov. p. 34.] blindness, because it is deprived of (the chance of) gathering. Therefore, it is not an advantage to us that we should always be led astray by names, nor that we should be deceived by outward appearances.
