The Maharal actually says exactly what OnTheBall said earlier, that knowing how doesn’t make you a Talmid Chacham. I was really surprised to see someone question that. Like a Maggid Shiur of mind once said, being able to steal doesn’t make you a thief.
“Being able to steal doesn’t make you a thief”. But you can’t steal unless you know how, obviously. Being able to learn doesn’t mean that you do learn, but somebody who isn’t mechunech in darkei halimud has very little hope of learning either. He can try – he can sit and finish lots of shas, and be able to translate it, but if you can’t understand anything then you aint learning either.
