Natural Right and Animal Right

In Ethics, II, xiii, Spinoza recognizes the existence of non-human "animated" individuals.  It, thus, seems to follow from the opening sections of ch. II of Political Treatise that corresponding to the activity of such an individual is a Natural Right.  In other words, implicit in his system are Animal Rights, though, therein the term connotes something other than it currently does--it sanctions what an animal instinctively does, e. g. killing and consuming a weaker animal, rather than protects it from what a human can do to it.  But, while, for Spinoza, political organization mediates potential interpersonal violence, it leaves unaddressed the power of humans over weaker animals.  Thus, his system has the perhaps unpleasant consequence of sanctioning the abuse of other animals by humans, which some might consider a decisive refutation of his concept of Natural Right.
