It is so wonderful to our neurologists that a man can see without his eyes, that it does not occur to them that it is just as wonderful that he should see with them; and that is ever the difference between the wise and the unwise: the latter wonders at what is unusual, the wise man wonders at the usual. Es tan maravilloso para nuestros neurólogos que un hombre pueda ver sin sus ojos, que no se les ocurra que es igual de maravilloso que vea con ellos; y esa es siempre la diferencia entre el sabio y el no sabio: este último se pregunta sobre lo que es inusual, el sabio se pregunta sobre lo usual.
Ralph Waldo Emerson, The Works of Ralph Waldo Emerson, vol. 3 (Essays. Second Series) [1909]
