This topic seems to have popped up in a few threads recently so I thought I'd put this together. Put simply do you believe in the concept of natural rights? That is to say rights that are "not contingent upon the laws, customs, or beliefs of any particular culture or government, and therefore universal and inalienable".
Personally I don't. I think that Hobbes had it right when he intimated that the only 'natural right' that a human being possesses is the right to strive for their own survival. Everything else exists only at the sufferance of your own strength or the kindness of others. It is part of what makes civilization so essential and so valuable, because by creating a society we attempt to lift ourselves out of that war of all against all. This allows for freedom of speech, property rights, press freedoms, freedom of worship, etc. Absent organized society these 'rights' would be purely theoretical.
