16. (xiv) But, in addition to examples, precepts and rules of conduct must be given.
In this way imitation will be supplemented and strengthened (on this point the reader may refer to our remarks in chap. xxi. canon ix.) Rules of life should therefore be collected from Holy Scripture and from the sayings of wise men, and should deal with questions such as: “Why should we strive against envy?” “With what arms should we fortify ourselves against the sorrows and the chances of life?” “How should we observe moderation in joy?” “How should anger be controlled?” “How should illicit love be driven out?” and similar questions, according to the age of the pupil.
17. (xv) Children must be very carefully guarded from bad society, lest they be infected by it.
For, owing to our corrupt nature, evil clings to us readily. The young must therefore be carefully shielded from all sources of corruption, such as evil society, evil conversation, and worthless books (for examples of vice, whether they make their entrance through the eyes or through the ears, are poison to the mind). And finally, sloth should be guarded against, lest through idleness the young be led to evil deeds or contract a tendency to indolence. The important thing is that they be kept continually employed either with work or with play. Idleness should never be permitted.
18. (xvi) Since it is impossible for us to be so watchful that nothing evil can find an entrance, stern discipline is necessary to keep evil tendencies in check.
For our enemy Satan is on the watch not only while we sleep, but also while we wake, and as we sow good seed in the minds of our pupils he contrives to plant his own weeds there as well, and sometimes a corrupt nature brings forth weeds of its own accord, so that these evil dispositions must be kept in check by force. We must therefore strive against them by means of discipline, that is to say, by using blame or punishment, words or blows, as the occasion demands. This punishment should always be administered
