“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.”
“Mr. Tesla On Sound Views.” Electrical Review, London, November 21, 1890.
