Laetitiae Sanctae §13

¹³ But men of carnal mind, who love nothing but themselves, allow their thoughts to grovel upon things of earth until they are unable to lift them to that which is higher. For, far from using the goods of time as a help towards securing those which are eternal, they lose sight altogether of the world which is to come, and sink to the lowest depths of degradation. We may doubt if God could inflict upon man a more terrible punishment than to allow him to waste his whole life in the pursuit of earthly pleasures, and in forgetfulness of the happiness which alone lasts for ever.
