Here's an example from Manyul Im's philosophy blog manyulim.wordpress.com/2009/08/25/agency-v
I'm pretty dubious about the "fact" in this quote. Do people actually play musical instruments less than they used to? What time period is he comparing against? Ten seconds on Google finds me this report from 2000 www.berksmusic.com/whymusic/whymusicgall
So this is an example of where a guy's basically invented a "fact" to try to confirm his assumption, which is that people make an effort (to learn a musical instrument) only under compulsion, or through lack of alternatives. We see the strength of the myth from the source of the quote. This guy Crawford is apparently a philosopher who chucked in the academic life to become a craftsman! He obviously made the choice to go and learn a craft (being a motorcycle mechanic) without any compulsion at all. Perhaps he wants to claim that most people don't do this in order to make himself seem more unique. Whatever the the motivation, his point is gibber.
