But I say: Considered from this point of view, the objector is certainly right; because if you only want to read so much and no more than how much you are actually going to cumbersomely put into practice, then of course a few chapters would be too much! But, with a different attitude, this will never become too much material, and the reader can immediately put everything he has read, into activity!
