Great article on the differences between idealogues / intellectuals and scientists / engineers. This article, IMHO has a lot to say about the current political gridlock in the US (let's face it, we're really seeing continuous showdowns and posturing by two opposing ideologies rather than any amount of pragmatism being applied to solve some of the huge problems facing this country), as well as any number of other topics. Does anyone else see a parallel with different approaches to teaching martial arts? A trap many traditionalists fall into is getting locked into what "should" work based on imperfect information passed down through multiple hands, or becoming obsessed with the perfection of the appearance of a technique rather than pressure testing their hypotheses in a more realistic venue... essential becoming a martial arts intellectual in this context rather than an engineer. I am not bashing traditional martial artists here (& am one myself), and understand that many do various forms of pressure testing (although what constitutes a valid pressure test or a realistic venue is open to debate). I do think that all of us need to practice our martial arts with an approach closer to that of a scientist or engineer, and validate or invalidate the ideas and techniques we are given to the best of our ability.
