"And if it were said of us that we're almost romantics, that we're incorrigible idealists, that we think the impossible, then a thousand and one times, we have to answer that yes, we are!"

“Let us not attempt, from the pontifical throne of realism-at-any-cost, to condemn all the art forms which have evolved since the first half of the nineteenth century for we would then fall into the Proudhonian mistake of returning to the past, of putting a straitjacket on the artistic expression of the man who is being born and is in the process of making himself.”

Except for Haiti and Santo Domingo, I have visited, to some extent, all the other Latin American countries. Because of the circumstances in which I traveled, first as a student and later as a doctor, I came into close contact with poverty, hunger and disease; with the inability to treat a child because of lack of money; with the stupefaction provoked by the continual hunger and punishment, to the point that a father can accept the loss of a son as an unimportant accident, as occurs often in the downtrodden classes of our American homeland.

“If, on the other hand, the groups of underdeveloped countries, lured by the siren song of the vested interests of the developed powers which exploit their backwardness, contend futilely among themselves for the crumbs from the tables of the world's mighty, and break the ranks of numerically superior forces ... our efforts will have been to no avail.”
