Of course, this is not the definition of the word "edifying". It has nothing to do with 'both parties'... it is about enlightening or uplifting the other party by definition. As part of the discourse one side will attempt to use or, even better, get you to define a word or term based on their directed questioning. To stay in a Socratic debate (note I use the words argument or debate rather than discussion) you must always be on the attack.
When all else fails you attack the other side and try to use terms that might insult them (e.g. my purported "problem with self reflection"). If you can anger your opponent you can throw off their thinking and leave them vulnerable to an unguarded response and a subsequent attack. It is like a chess match where you attempt to remain on the attack... but guard your defenses VERY carefully. One wrong defensive move can leave you open to an attack that will decimate your position and you will lose the argument. The "I like having my assumptions challenged" line is a clever one. It can be disarming as it indicates self reflection. But, don't fall for the trap. None of the assumptions (to which he now admits, see how it works) have changed and his post shows no actual consideration or openness to actual discussion. It is, in short a ruse.
Now, WilliamC and I could probably go back and forth on this for quite some time (with no winner declared). But, neither of us are going to actually change our minds or give the other's position any thought whatsoever. That would result in mental weakening and lead to defeat in the adversarial, Socratic method. Now, I did graciously pass on the obvious attack when the word edifying was used and redefined... I also left the word assumption hanging in the wind... we all know what happens when you assume. Regardless, I honestly believe the Socratic Method is unworthy when trying to have an honest discussion... He may believe it is and we will probably never see eye to eye on this. Our disagreement does not matter to the point of winning your parents over to RP which I believe is the real issue here.
Ignore both of us (except me, of course, because I am right)... speak with your parents honestly and consider some of the other thoughts and ideas that have been posted in this thread.
this method (Socratic) is taught in schools, in debate and used by lawyers...
it demonstrates why lawyers will be some of the first against the wall when the revolution comes
as you can see it is no wonder they executed Socrates... if only they had done it sooner!
The method is used quite a bit on these forums... if you see it being used my best advise is to walk away
