"My dear friends, now and forever, I renounce, have renounced and will go on renouncing copyrights. My only wish is that these books be sold at low price, affordable to the poor, affordable to all the children of God. I wish that even the poorest, most destitute citizen be able to obtain these books with the few pennies he carries in his pocket. In fact, I do not have any income; I do not demand anything in exchange for my works. Whosoever wants to publish them, let him publish for the benefit of diseased mankind."
