Quote by Malcolm Stevenson Forbes
What's an expert? I read somewhere, that the more a man knows, the more he knows, he doesn't know. So I suppose one definition of an expert would be someone who doesn't admit out loud that he knows enough about a subject to know he doesn't really know how much.
Summary
This quote suggests that an expert is not someone who claims to know everything about a subject, but rather someone who acknowledges the vastness of knowledge and recognizes their own limitations. An expert understands that the more they learn, the more they realize how much they still do not know. Thus, an expert is humble and hesitant to proclaim complete mastery, as they are constantly aware of the extent of their ignorance despite their expertise in a specific area.
