A little while ago, not much more than a few days ago, I was a child who went about in a world of colors, of hard and tangible forms. Everything was mysterious and something was hidden, guessing what it was was a game for me. If you knew how terrible it is to know suddenly, as if a bolt of lightning elucidated the earth. Now I live in a painful planet, transparent as ice; but it is as if I had learned everything at once in seconds.
Letter to Alejandro Gómez Arias, (29 September 1926)
