How can you justify your rights? Should we need to? I think rights should perhaps be viewed as preferences that must be respected legally or morally. You can think about the Golden rule, for example. We should treat others how we would like to be treated to some extent because we all benefit if we all agree to do this simultaneously. This allows us to create trust and form a small society. But, what happens when you treat someone how you would like to be treated but they don't like how you are treating them? For example, imagine that a man wants to be euthanized because he hates his life. Does that mean it would be ok for him to euthanize someone else under the Golden Rule? Well, not exactly. There's a bit of a paradox in the Golden Rule. The suicidal man might wish to be euthanized but he does not wish to have one of his preferences violated. Therefore, he wouldn't be following the Golden Rule if he euthanized an unconsenting individual. Because one has to respect the other persons preference to follow the Golden Rule unparadoxically, we could reframe the Golden Rule as "treat others how THEY wish to be treated". In other words, give everyone what they want. But, of course, we cannot give everyone what they want and so we can't follow that rule completely. It appears to be more reasonable to require that people don't give people what they don't want instead. In other words, one ought not to violate the preference of others by an act of commission(although one is not obligated to perform an act of commission to satisfy one's preferences). Over time, we made a list of preferences that we think should never be violated by an act of commission. These include:
-The preference to utter any statement or no statement at all(The Right to Free Speech)
-The preference to practice any religion or no religion at all(The Right to Religion)
-The preference to not be murdered(The Right to Life)
-The preference to not be enslaved(The Right to Freedom)
I know this isn't probably the whole explanation for human rights but I think it's a good start. In conclusion, human rights are a byproduct of a collective human desire to exist with one another in peace and harmony. We all benefit by avoiding the unjust violation of anyone's preferences and we wish that no one would violate ours unjustly
