Assuming that there are natural rights and human rights, are they co-extensive - so that to have (all) natural rights is to have (all) human rights and vice versa? Is there any difference in their contents - in what they are rights to or from - and is the basis of natural rights, their justificatory ground, that same as that of human rights ?
Natural rights encompasses human rights. Humans are, after all, a component of nature. I would add the diagram, but couldn't do it now, as I am having problems attaching the pictures.
To get back to the topic, natural rights encompasses human rights. You could consider natural right as a universal set, and human rights as its subset. Hope this answer helps.
