Memorabilia

I think that I have said enough to show that Socrates stated his own opinion plainly to those who consorted with him: I will now show that he also took pains to make them independent in doing the work that they were fitted for. For I never knew a man who was so careful to discover what each of his companions knew. Whatever it befits a gentleman to know he taught most zealously, so far as his own knowledge extended; if he was not entirely familiar with a subject, he took them to those who knew.

He also taught them how far a well-educated man should make himself familiar with any given subject.For instance, he said that the study of geometry should be pursued until the student was competent to measure a parcel of land accurately in case he wanted to take over, convey or divide it, or to compute the yield; and this knowledge was so easy to acquire, that anyone who gave his mind to mensuration knew the size of the piece and carried away a knowledge of the principles of land measurement.
