“You state that I have misinterpreted my results, and it looks as though you believe my views to be unsound. Your arguments are those of an eminent scholar. I was myself a fair scholar. For years I pondered, so to speak, day and night over books, and filled my head with sound views–very sound ones, indeed–those of others.

“But I could not get to practical results. I then began to work and think independently. Gradually my views became unsound, but they conducted me to some sound results.”

–Nikola Tesla
