tachyon:No, the name implies that DIR *IS* the right way. DIR = TRUE
It is implied that if you disagree with DIR then you *are not* seeking the right way. NOT DIR = FALSE
Wrong. The name implies a goal. The goal is to do it right. They progress toward this goal by evolving their diving methodology based on sound principles.
tachyon:By the laws of logic, if DIR = TRUE than anything which is NOT DIR = FALSE. Since this is not true, this is a situation where pure logic can not be applied as simply as you imply.
You don't understand logic then. The first law of logic is the law of non-contradiction. If you believe the way you are doing it is the right way, you must believe the other ways are wrong. However, all DIR adherents share is the belief that their way is the closest approximation of the right way, and a commitment to working to converge it upon the right way.
tachyon:Some DIR procedures are demonstrably NOT the right way to do things in all situations.
An assertion often made, but seldom or never supported. Lose the vague allusions and offer clear examples.
tachyon:Sometimes, they're not even the right way to do things in technical / cave diving.
And again.
tachyon:Whenever I've seen them pointed out, some DIR disciples assault not the issue, but the credibility of those contesting the procedures...
Cite? That's a conversation I'd like to hear.
tachyon:Am I a candidate for DIR? No. I'm overweight by a large margin. That makes me a 'stroke' in any DIR diver's book. You know what? I don't really care.
And thus your real motivation here is revealed.
tachyon:There have been DIR proponents who have stated explicitly in this thread that not only am I not acceptable to take their training, but that I'm not acceptable as a dive buddy, despite never having met me and having no idea of my diving skill.They can magically tell that I'm not 'worthy' because of any of a number of protocols on equipment, training and fitness.
Well, the fitness aspect alone is a sound basis for a decision. No other information is needed. There is no degree of skill that will mitigate a heart attack, or insufficient stamina to completely weather a crisis. While I don't necessarily share their criteria for who I dive with, it's clearly rational and consistent.
tachyon:Diving with someone who has superior skills should be an opportunity to learn and improve on your own skills. Once you've mastered those skills, you should pass them on to people whose skills aren't as good as your own. That is the obligation of the student in martial arts and academe. I see it as an unstated rule in the diving industry as well and consider that a good thing.
I see a disconnect in this cycle with DIR's philosophy if not it's practice. If you limit your diving partners to those who are on some 'approved' list, you limit the skills you can learn to those posessed by that group, especially if any skill learned or demonstrated is 'dangerous' if it isn't already in your 'Bible'.
There are two problems with your application of this principle to this scenario. First, if one is to share knowledge, the recipient must have an open mind and be willing to learn. An obligation to teach is not an obligation to entice with sweet talk. Why lead a horse to water if he declares he's not thirsty? Second, as to limiting one's pool of 'teachers,' it's only prudent to discriminate in what knowledge you absorb. I choose not to read the National Enquirer; is that a bad limitation of my exposure to knowledge?
