"A good teacher must know the rules; a good pupil, the exceptions"
About this Quote
Fischer, a physician and prolific writer in an era when modern medicine and laboratory science were rapidly professionalizing, is pushing back against education as mere credentialed certainty. The teacher must "know" rules: mastery, competence, the responsible transmission of hard-won method. The pupil, though, earns the higher compliment. To know exceptions is not to be sloppy or contrarian; it is to see pattern and anomaly at once, to understand rules so well you can locate their limits without confusing those limits for failure.
The subtext is also a critique of authority. Teachers are tasked with enforcing stability, but students - the good ones - are invited to test it. Fischer is arguing for a kind of apprenticeship in skepticism: respect the framework, then look for the places it does not fit. That is how disciplines evolve, and how a learner becomes more than a repeater of other people's certainty.
