Quote of the Day – The Problematical Quest for Expertise

In any normal domain of expertise, even the most knowledgeable of specialists can’t come close to knowing everything about the domain. The breadth of knowledge that one would need to assimilate in order to be an expert in every nook and cranny is so cast that setting oneself such a goal makes no sense. And of course the idea of being an expert ‘in every nook and cranny’ is itself problematical, since when one uses a magnifying glass, every domain shatters into yet further subdomains.
