The danger of sticking with established theory because everyone of notes says it is so, is that it leaves one stuck in the days of plogiston and the ether. I am not suggesting that the opposite is true, but the only reason to stick to an existing view is because the underlying theory shows it to be correct, and experiment confirms it. Don't have an unduly open mind but never close it entirely.
