(100) That they have been preserved in great measure by Gentile hatred, experience demonstrates. (101) When the king of Spain formerly compelled the Jews to embrace the State religion or to go into exile, a large number of Jews accepted Catholicism. (102) Now, as these renegades were admitted to all the native privileges of Spaniards, and deemed worthy of filling all honourable offices, it came to pass that they straightway became so intermingled with the Spaniards as to leave of themselves no relic or remembrance. (103) But exactly the opposite happened to those whom the king of Portugal compelled to become Christians, for they always, though converted, lived apart, inasmuch as they were considered unworthy of any civic honours. (104) The sign of circumcision is, as I think, so important, that I could persuade myself that it alone would preserve the nation for ever. (105) Nay, I would go so far as to believe that if the foundations of their religion have not emasculated their minds they may even, if occasion offers, so changeable are human affairs, raise up their empire afresh, and that God may a second time elect them. (106) Of such a possibility we have a very famous example in the Chinese. (107) They, too, have some distinctive mark on their heads which they most scrupulously observe, and by which they keep themselves apart from everyone else, and have thus kept themselves during so many thousand years that they far surpass all other nations in antiquity. (108) They have not always retained empire, but they have recovered it when lost, and doubtless will do so again after the spirit of the Tartars becomes relaxed through the luxury of riches and pride. (109) Lastly, if any one wishes to maintain that the Jews, from this or from any other cause, have been chosen by God for ever, I will not gainsay him if he will admit that this choice, whether temporary or eternal, has no regard, in so far as it is peculiar to the Jews, to aught but dominion and physical advantages (for by such alone can one nation be distinguished from another), whereas in regard to intellect and true virtue, every nation is on a par with the rest, and God has not in these respects chosen one people rather than another. CHAPTER IV. - OF THE DIVINE LAW. (1) The word law, taken in the abstract, means that by which an individual, or all things, or as many things as belong to a particular species, act in one and the same fixed and definite manner, which manner depends either on natural necessity or on human decree. (2) A law which depends on natural necessity is one which necessarily follows from the nature, or from the definition of the thing in question; a law which depends on human decree, and which is more correctly called an ordinance, is one which men have laid down for themselves and others in order to live more safely or conveniently, or from some similar reason.
