I appreciate the unfortunate busy-ness modern life demands, if these kind of ideas aren't seriously upheld they will never find a footing. If there is no model for stopping, physically and emotionally, the insistent, demanding voices of production and consumption are difficult to subdue, leaving no room for the spiritual. Unfortunately, if we see praise as the positive, then discipline is the negative. If the application is effective we have a good model of how discipline is applied to another and we can apply that to ourselves. There are increasing signs of social disorder and a lack of control.
Teachers increasingly function as social workers and are often no more than disciplinarians.
Personally, I think society has a generally over-liberal approach to discipline. Children don't know right from wrong. They build up a list of likes and dislikes which usually bears little resemblance to any moral code and often is outside many social codes. The penalties, later in life, for not having been taught, are not only uncomfortable for the individual but for the society at large. Discipline is a delicate balance between abuse and indulgence.
