I linked to you some of the original authors and philosophers of natural rights. I understand what they imagined them to be because I've read their work. They imagined them to be gifts from God. I'm not debating them, I'm debating you. The only rationale relevant to this conversation is yours and mine. I only provided them for historical context but to attribute their beliefs or my own to you would be unfair.
The links then were an unneeded deflection.
As I said, those are things that can be observed or measured, things that exist in physical reality.
How do you know what exists in reality? Whose reality do you mean? Is there only one single reality, such that perception of any other reality is by definition false? What is your proof of this unified reality?
Things like you, me, the phone I'm typing this message on. Things that can be seen and measured and independently accounted for beyond your subjective feelings.
Take the temperature for instance. You and I can be standing outside together and we might not be able to agree on whether it's hot or cold outide. This represents our subjective opinions. If we were to both pull out thermometers however, we would be able to use the mercury inside to detect and measure the temperature of the air. This measurement would represent an objective fact. It has nothing to do with how you feel about the temperature but about how the heat from the air affects the mercury.
"Seen" and "measured" are just other words for "perceive." Perception is subjective. You perceive them, but that doesn't make them real. Reality by that definition means nothing more than our perception of reality. We measure things like temperature, by methods that we perceive to be accurate, not that we can prove are accurate.
Best we could agree for any measuring method is that it is consistent. Even then, it could very well be consistently inaccurate, or we could only be perceiving that it is consistent. It could be generating random numbers that happen to match several times in a row. Or we could be agreeing due to factors having nothing to do with objective reality.
Example: Is gravity real?
No, it is not.
We perceive a force pulling us toward the Earth. Newton identified it as gravity and for decades we called that force gravity. We based much science on that perceived force, called "gravity." Newton and other very smart scientists used formulas to measure this force with precision in different situations.
The science worked in the overwhelming majority of cases. We could measure that pull of gravity with scales. One hundred people could look at a rock on a scale and all see the same result. Ten thousand people could walk by and agree that gravity was pulling the rock toward the earth with a force of XX pounds.
They would be wrong.
Now, thanks to Einstein, we "understand" that objects with mass bend space and that "gravity" is not a real force at all. Woo-hoo! Now we "know" and we are much smarter than those primitive Newtonians, who were not really much smarter than the primitive people who believed some kind of "Earth God" pulled objects toward the Earth. Both believe in a force that we now believe non-existent.
That is our new "reality," but it will likely be overtaken by some other "reality."
Or, maybe you can prove that Einstein's or any other explanation for the perceived force of gravity is objectively true and will never be refuted?
Oops, did that above.
I believe I've accomplished this as well but by all means, pick apart my logic if you can.
Just did.
I don't need to. I can accept your dismissal as good enough for me. You don't believe that is enough to prove rights exist. Okay. So where is this proof? Can we observe its affects independent of you? Something beyond a motivation for you to go to war or leave out milk and cookies?
What is proof? You gave the example of perception of your phone or of temperature as "proof" that they exist, and I showed that such a perception is not proof.
So please prove something - anything - so I know that proof is a real thing.
