Speaking of someone having a right is a right of entitlement. Human rights are rights of entitlement. Humans have these rights for being human. It is also important to differentiate between intrinsic and instrumental value. Something of intrinsic value is valuable because of what it is.
Instrumental value refers to something that is valued based on what it can do.
Humans are valued intrinsically because humans are precious because they are human . By these definitions it becomes easy to see why humans are so special and why they deserve rights. Human rights have to come from somewhere, but where do they stem from. The source of human rights might be human nature. It is our nature, as humans, to want to be treated with equality in all circumstances.
