Quote by G.K. Chesterton

“I could not help laughing at the ease with which he explained his process of deduction. “When I hear you give your reasons,” I remarked, “the thing always appears to me to be so ridiculously simple that I could easily do it myself, though at each successive instance of your reasoning I am baffled until you explain your process. And yet I believe that my eyes are as good as yours.” “Quite so,” he answered, lighting a cigarette, and throwing himself down into an armchair. “You see, but you do not observe.”
