It is a most true thing that all the things of the world have to have an ending to their existence. But these only run the entire course that is generally ordained by Heaven, which does not disorganize their body, but keeps it so organized that it is not changed, or if it is changed, it is for its welfare and not its injury. And as I speak here of mixed bodies, as are Republics and (Religious) Sects, I say that those changes are for the better which bring them back to their (original) principles. And, therefore, those are better organized and have a longer existence, which through their own means are able frequently to renew themselves, or which through some accident outside the said organization come to that renewal. And it is something clearer than light, that these bodies which do not renew themselves, do not endure. The means of renewing them ((as has been said)), is to bring them back to their (original) principles. For all the principles of Sects and Republics and of Kingdoms must have within themselves some goodness, by means of which they obtain their first reputation and first expansion.
