I find myself looking upon this subject with mixed thoughts.
I'm fairly sure I'm not alone.
Of all forms of discipline, self-discipline is the best. The best form of control is self-control. In fact IMHO the Bill of Rights and the Constitution don't work to well without them. And IMHO both are heavily based on them.
I was once told by my GrandFather that if I was unable to develope self-discipline to beware as there was plenty of people in the world waiting to apply their form of discipline upon me. If I could not control myself .... same thing. He pointed out the NAZI's and the things they did, and threw in Joseph Stalin, etc.
Children, and sadly some young people, need to develope self-discipline and self-control.
The manner used to teach them is the issue involved I think.
Violence is all around us. Happening every second of every day. It is Nature. And Nature is very unforgiving.
True we are thinking beings. This supposedly puts us above Nature?
I find myself thinking WTF is with this attitude/ thought process that equates advanced civilization with non-violence? It seems un-natural, anti-nature, even possible anti-progressive?
When I was young, shut-up Silat LOL:lol, you could say whatever pleased you IF you could take the results. Say some things and say them about them about certain people and you would find yourself dealing with the results, possibly at the local Dr. office, or the hospital emergency room. The police and the courts did sometimes get involved but there was a mmm "code" involved. No person had to except certain things. A reasonable person kinda thing.
The base for this code was often would YOU care to have such things said about YOU or loved one. That and reputation. People tended to judge you, ya there it is the word "judge", by your reputation. If it was KNOWN you lied ALLOT .... well you can get the picture.
Now it's to the courts and pay the lawyers etc.
Used to be cheaper, most of the time, to deal with it the other way.
OOPS kinda got off topic here sorry...........
Anyways.........
Some believed pain to be the fastest teacher. And for some people, with a certain type mindset, the best, and possibly only, teacher.
The concept is THINK! Before you do or say anything THINK! That is the totallity of the concept.
How to get some people to think is the problem. Far too many don't think it through before they speak, type, or do something.
Consideration, walk a mile in the shoes, whatever. Too many seem to avoid such.
DANG off topic again.
IMHO there are people that exist in the world that place the rest of us in danger every second of every day. (YA YA I know, some call those people politicians

)
What do you do with these people? How do you deal with these people?
IMHO Some, unfortunatly, should/must be removed for the saftey of our families. ( the news media report stories that prove this far too often )
SO IMHO an advanced civilization does NOT equate with non-violence. We haven't come far enough as a species to create such a society. We still have salvery, we still have people lusting for power and control seeking leadership of countries, we still have individuals willing to do murder to acheive their goals. IMHO NO amount of media fluff can change that reality.
