But this width and depth of
passion is still more immense in man, because man's intellect grasps universal
good and man's will desires that boundless good which is found in God alone.
Hence when man's will does not follow the straight road to God, when man seeks
supreme happiness not in God but in creatures, then his concupiscence becomes
insatiable, because he has unlimited desires for a good that is limited.
