§ 129. Oral instruction may (1) give the subject, which is to be learned, in a connected statement, or (2) it may unfold it by means of question and answer. The first decidedly presupposes the theoretical inequality of the teacher and the taught. Because one can speak while many can listen, this is especially adapted to the instruction of large numbers. The second method is either that of the catechism or the dialogue. The catechetical is connected with the first kind of oral instruction above designated because it makes demand upon the memory of the learner only for the answer to one question at a time, and is hence very often and very absurdly called the Socratic method. In teaching by means of the dialogue, we try, by means of a reciprocal interchange of thought, to solve in common some problem, proceeding according to the necessary forms of reason. But in this we can make a distinction. One speaker may be superior to the rest, may hold in his own hand the thread of the conversation and may guide it himself; or, those who mingle in it may be perfectly equal in intellect and culture, and may each take part in the development with equal independence. In this latter case, this true reciprocity gives us the proper dramatic dialogue, which contains in itself all forms of exposition, and may pass from narration, description, and analysis, through satire and irony, to veritable humor. When it does this, the dialogue is the loftiest result of intelligence and the means of its purest enjoyment.
