At one of my regular karate dojo, which is shared by another eastern martial arts group. There are numerous quotes on the wall, one of them put there by other group is by Abraham Lincoln - "It is better to remain silent and be thought a fool than to open one's mouth and remove all doubt."
I think that this is very wrong. Surely there is a time and place for asking questions, but some of those times and places should be inside the dojo. I think the quote above implies obedience to a degree that is unacceptable and will create "monodrone martial artists" that never think twice of asking questions or disagreeing with the instructor on anything.
Anybody elses thought on this quote in particular, should create some good discussion. Also other quotes and maybe experiences anyone else has had with bad philosophy would be interesting to hear about!
