18 Now there are two passions today dominant in the profound lawlessness of morals - an unlimited desire of riches and an insatiable thirst for pleasures. It is this which marks with a shameful stigma our epoch; whilst it goes ceaselessly from progress to progress in the order of all which touches the well-being and convenience of life, it seems that in the superior order of honesty and of moral rectitude a lamentable retrogression leads it back to the ignominies of ancient paganism. In that measure, in truth, wherein men lose sight of eternal goods which Heaven reserved for them, they permit themselves to be more taken in by the deceitful mirage of the ephemeral goods here below, and once their souls are turned down towards the earth, an easy descent leads them insensibly to relax themselves in virtue, to experience repugnance for spiritual things, and to relish nothing outside the seductions of pleasure. Hence the general situation which we note: with some the desire to acquire riches or to increase their patrimony knows no bounds; others no longer know, as formerly, how to bear the trials which are the usual result of want or poverty; and at the very hour in which the rivalries We have pointed out set by the ears the rich and the proletariat a great number seem to wish to further excite the hatred of the poor by an unbridled luxury which accompanies the most revolting corruption.
