there is no expression in any ancient or medieval language correctly translated by our expression ‘a right’ until near the close of the middle ages: the concept lacks any means of expression in Hebrew, Greek, Latin or Arabic, classical or medieval, before about 1400, let alone in Old English, or in Japanese even as late as the mid-nineteenth century. From this it does not of course follow that there are no natural or human rights; it only follows that no one could have known that there were.
