Mock dialogue of the Theist/Atheist discussion here.

I don't have objective value.  That my thought processes exist is objectively verifiable.  You are reading proof of their existence in the form of out put.  But they have no objective value.  Objective value is an oxymoron.  Value, unlike weight is inherently subjective.

Do you have subjective value? If so, how so? Why do you believe in your perception of value of yourself? If not, then you do think it's irrational to value oneself?

I believe I have an objective value and subjective value. My parents have a subjective value of me. I have a subjective value of me. But I don't believe subjective value of a person is possible without a belief that they have objective value.

So to me, personally, I believe that would be a contradiction in terms. The only way to have subjective value  of yourself is to believe there is an objective value of yourself.

Of course I value myself. I hope I have value to others. That doesn't mean I think I have value in any objective cosmic sense. Nothing does. Value is placed on a thing by someone. My value varies we the beholder. It is a preference. With the exception of sociopaths people place value on other people. The value we place on things including people, tells you about us, not the things not the things we value.

Gold can be used as a medium of exchange, or to make things people like to look at, or for industrial purposes. The value we place on it is a function of human desires not the gold itself. The gold has objective properties (mass, conductiviy, melting point, reactivuty, etc.) but it does not have objective value. It's value varies from person to person and culture to culture. Value is subjective.

The existence of people or gold, is an objective reality, just as it is an objective reality that there were once no people. Like gold, you can say other objective things about people. How much we weigh, how long we live, our color, how are bodies function, how we can affect our environment, that we have emotions, and thoughts. But those are not value. Our value is entirely subjective.
