Leo XIII, 1878-1903

rate of pay, yet there is always underlying this something from natural justice, and this greater and more ancient than the will of those who make the contract, namely, that the pay must by no means be inadequate to support the worker, who indeed is frugal and of good character. But if the worker, forced by necessity, or moved by fear of a worse evil, accepts the harder condition, which, even if he does not wish it, must be accepted because it is imposed by the employer or the contractor, this certainly is to submit to force, against which justice cries out. . . . If the worker obtains sufficient pay, so as by it to be able to sustain himself, wife, and children comfortably, he will without difficulty apply himself to thrift, if he is wise, and he will bring it about, as nature herself seems to urge, that, after expenses are deducted, some be left over whereby he may attain a moderate estate. For we have seen that the case which is being discussed cannot be solved by effective reasoning except by this assumption and principle: that the right to private property must be held sacred. . . . Nevertheless, these benefits cannot be attained except by the enormity of contributions and taxes. For, since the right to possess private property is granted not by the laws of man but by nature, the authority of the state cannot abolish it, but only temper its practice, and order it to the common good. Therefore, it would act unjustly and inhumanely, if it should detract from private property more than is just, under the name of taxes. . . .

1938d. It is comforting to observe that societies of this kind are being formed generally, either composed entirely of workers, or from both classes; moreover, it is to be desired that they grow in number and in effective influence. . . . For, it is permitted man by the right of nature to enter private societies; moreover, the state is established for the protection of natural right, not for its destruction; and so, if it forbids the formation of associations of citizens, it clearly acts at odds with itself, since it itself, as well as private associations, come into existence from a single principle, that men are by nature social.—Occasions sometimes arise when it is just for laws to forbid such societies, namely, if they deliberately aim at something which is clearly at variance with probity, justice, and the welfare of the state.¹
