El prefacio pertenece a la edición de 1798 que Malthus realizó de forma anónima, por lo que en la cita se refiere a sí mismo.
Original: «The view which he has given of human life has a melancholy hue, but he feels conscious that he has drawn these dark tints from a conviction that they are really in the picture, and not from a jaundiced eye or an inherent spleen of disposition».
