As for those whose style is inflated or vicious, and whose language reveals a passion for high-sounding words or labours under any other form of affectation, in my opinion they suffer not from excess of strength but of weakness, like bodies swollen not with the plumpness of health but with disease, or like men who weary of the direct road betake them to bypaths. Consequently the worse a teacher is, the harder he will be to understand.
I have not forgotten that I stated in the preceding book, when I urged that school was preferable to home education, that pupils at the commencement of their studies, when progress is as yet but in the bud, are more disposed to imitate their schoolfellows than their masters, since such imitation comes more easily to them. Some of my readers may think that the view which I am now maintaining is inconsistent with my previous statement.
