Why are rights not self-evident?

Individual rights are not self-evident but are, like the theory of gravity, objective discoveries based on the facts of reality.

Individual rights are not a perceptual self-evidency but are a tremendous discovery that took humanity centuries of observation and thought to discover and formulate.

Individual rights are the objectively identified requirements for a human being to live a flourishing life in society. It is because they are not self-evident that there is much confusion over the nature of rights and how they are applied.
