The classical concept of natural rights is more or less synonymous with the concept of human rights or moral rights. Rights are essentially claims against others to be treated in certain ways.Natural rights differ from conventional rights, which are rights created by people in a social, legal or political context.
Normative ethics, also called moral theory, is broad field of philosophical study about how we should live or behave. Natural Rights based ethics represents a cohesive and common sense normative position which upholds a necessary respect for human dignity.
We have natural or moral rights by virtue of being human. For this reason, natural rights are sometimes referred to as inalienable or absolute. Human beings have dignity, and thus we all have the inherent right not to be killed, raped, coerced, or stolen from.
