Ayn Rand once said that the concept individual rights was a redundancy since rights can only belong to individuals. In the same way I think the concept human rights is also a redundancy since rights can only belong to rational beings i.e. humans. I raised this question at a study group meeting and it was agreed that human rights could have a valid use when used to differentiate from invalid rights like for example animal rights or plant rights.
But I still don't like the concept human rights. It's too collectivist and could mean individual rights and/or group rights. Politicians routinely use 'human rights' to hide the fact that they support group rights in violation of individual rights.
I think I'll have to settle for the fact that its validity depends on how it is used.
