He's using commas to separate individual clauses of the sentence. Slavic languages do this, and probably some others too. >This should not stop us, the humanity. This doesn't seem like something a modern native speaker would say, but it's basically the same thing as in sentences like this: Montfort was a younger son of Simon de Montfort, 5th Earl of Leicester, a French nobleman and crusader, and Alix de Montmorency. , 5th Earl of Leicester, is inserted here to clarify meaning, the same way you might insert a group identifier after a we. Perhaps it might seem less out of place if he used it at the beginning of the sentence, like: We, the humanity, shouldn't let this stop us.
