I said, like an unthinking fool, 'The seeing eye?—I shouldn't count on that for much—I suppose we all have it.' 'No,' he said; 'very few have it.' Then he explained, and made his meaning clear. He said the common eye sees only the outside of things, and judges by that, but the seeing eye pierces through and reads the heart and the soul, finding there capacities which the outside didn't indicate or promise, and which the other kind of eye couldn't detect.
