God Himself says this speaking through the voice of nature; and inasmuch as it is not His will to have Nature supply every place with all the necessaries of life, He ordains that some nations excel in one art and others in another. Why is this His will, except it be that He wished human friendships to be engendered by mutual needs and resources, lest individuals deeming themselves entirely sufficient unto themselves should for that very reason be rendered unsociable? So by the decree of divine justice it was brought about that one people should supply the needs of another, in order, as Pliny the Roman writer says,[1] that in this way, whatever has been produced anywhere should seem to have been destined for all. Vergil also sings in this wise: “_Not every plant on every soil will grow_,”[2] and in another place: “_Let others better mould the running mass Of metals_,” etc.[3] - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Hoc igitur qui tollunt, illam laudatissimam tollunt humani generis societatem, tollunt mutuas benefaciendi occasiones, naturam denique ipsam violant. Nam et ille quem Deus terris circumfudit Oceanus, undique et undique versus navigabilis, et ventorum stati aut extraordinarii flatus, non ab eadem semper, et a nulla non aliquando regione spirantes, nonne significant satis concessum a natura cunctis gentibus ad cunctas aditum? Hoc Seneca[4a] summum Naturae beneficium putat, quod et vento gentes locis dissipatas miscuit, et sua omnia in regiones ita descripsit, ut necessarium mortalibus esset inter ipsos commercium. Hoc igitur ius ad cunctas gentes aequaliter pertinet: quod clarissimi Iurisconsulti[5a] eo usque producunt, ut negent ullam rempublicam aut Principem prohibere in universum posse, quo minus alii ad subditos suos accedant, et cum illis negotientur. Hinc ius descendit hospitale sanctissimum: hinc querelae: _Quod genus hoc hominum? quaeve hunc tam barbara morem Permittit patria? hospitio prohibemur harenae._[6a] Et alibi _litusque rogamus Innocuum et cunctis undamque auramque patentem._[7a] Et scimus bella quaedam ex hac causa coepisse, ut Megarensibus - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
