Commerce is a cure for the most destructive prejudices; for it is almost a general rule that wherever we find agreeable manners, there commerce flourishes; and that wherever there is commerce, there we meet with agreeable manners.
Let us not be astonished, then, if our manners are now less savage than formerly. Commerce has everywhere diffused a knowledge of the manners of all nations: these are compared one with another, and from this comparison arise the greatest advantages.
Charles de Secondat
Baron de Montesquieu 1748
