Teaching conditions were not ideal. Study groups would work together on the quarry and station themselves in a circle around the leader of the seminar. The style of teaching was Socratic in nature; ideas and theories were elucidated through the leaders asking and answering questions. . . .
As these courses became known in the general section, we began to get queries from our men on the other side. This started what became a kind of correspondence course with the prisoners in the general section. The teachers would smuggle lectures over to them and they would respond with questions and comments.
This was beneficial for us as well as for them. These men had little formal education, but a great knowledge of the hardships of the world. Their concerns tended to be practical rather than philosophical. . . . Such questions were immensely valuable and forced one to think hard about one's views.
