“The very helplessness of the public which makes it necessary for them to consult the experts also makes it impossible for them to judge how expert they are.”

“Dwelling on your problems doesn’t fix them; it just makes you an expert at them.”

“Nobody is publicly accepted as an expert on poetry unless he displays the sign of poet, mathematician, etc., but universal men want no sign and make hardly any distinction between the crafts of poet and embroiderer.Universal men are not called poets or mathematicians, etc. But they are all these things and judges of them too. No one could guess what they are, and they will talk about whatever was being talked about when they came in. One quality is not more noticeable in them than another, unless it becomes necessary to put it into practice, and then we remember it.”

“None of our men are 'experts.' We have most unfortunately found it necessary to get rid of a man as soon as he thinks himself an expert because no one ever considers himself expert if he really knows his job. A man who knows a job sees so much more to be done than he has done, that he is always pressing forward and never gives up an instant of thought to how good and how efficient he is. Thinking always ahead, thinking always of trying to do more, brings a state of mind in which nothing is impossible. The moment one gets into the 'expert' state of mind a great number of things become impossible.”

“Computer science education cannot make anybody an expert programmer any more than studying brushes and pigment can make somebody an expert painter.”

“An expert is someone who knows some of the worst mistakes that can be made in his subject, and how to avoid them.”
