"Not so. It is possible to accept convention to the point that the original questions are forgotten."
It's also possible not to do that, and to question current scientific thinking. That's how science progresses. Those who succeed in scientifically demonstrating that a current theory is incorrect end up with Nobel Prizes.
It is very difficult to ignore convention or even see it since convention is arrived at by many who are well-qualified to think about the subject. It was Bridgman's goal to reorient scientific thinking so that a disruption such as followed Einstein's reappraisal of the nature of physics in the electromagnetic realm would not be possible. Bridgman did not live long enough or didn't think fast enough to accomplish that reorientation, but his suggestion that those involved in physics stand back a little and take a good look at their conventions can still be taken.
