“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.”
~ Malcolm Forbes
We can be absolutely 100% certain about something until new light is shed on the subject. Then what?
Have you noticed how it’s the professed experts, being so attached to being an “expert”, who are the last to embrace the new found truth? So much for being an expert!
Keep an open mind, my friend, a beginner’s mind. New discoveries are just around the corner.
