A difference in degree maybe, but not in kind. Trust is a central part of science, without it no advance would be possible. > being able to, in principle, rederive things from scratch Basically no scientist nowadays has any hope of being able to rederive everything from scratch. Not even in mathematics, where experiments are cheap, can you avoid relying on theorems from outside of your area of expertise.
