First, you say that humans have value subjectively, because we give it to ourselves and because it favors our survival of us all. Then you say that this is not objectively the case. Do we perceive it or decide it? Is it real or is not real?
It is real to us. That's kind of the thing with subjectivity.....
Remember that what I am arguing isn't whether or not we can recognize the existence of values on our own or not, but rather their existence in the first place and why they exist.
Their existence are dependend upon humans existing.
Human morality, for example, exists between the ears of humans. So does empathy.
In fact, this argument assumes that you recognize some fundamental values as good or bad.
Sure. From a human perspective though...
Here's a question for you: Why should humanity survive?
"should"?
Because we prefer life over death. Well, most of us do, anyway.
Objectively speaking, as I previously said, if we do not have value, then it means we are delusional to believe so, because it's not real, except in our heads.
I don't see how subjectivity translates to delusional.
I prefer cucumber over tomato's. That's a subjective preference. It's very real. It's not delusional. I genuinely prefer cucumber over tomato's.
This is not an objective truth. It's a subjective one.
It doesn't lose its meaning, simply because it is my subjective preference.
Like a psychosis is real for the psychotic
That's an entirely different ball game.
Psychosis is pretty much hallucination in various degrees. It has nothing to do with subjectivity vs objectivity.
We would be conferring to ourselves a value we don't really have.
Except we do really have these values, and for good reason. Well, most of us anyway.
Society would not function or survive without it.
But it is only important from a human perspective.
A gold fish doesn't care if you kill another human.
Should we value a human life and why?
Because we like to survive, and preferably as comfortably as possible.
Because we value safety and well being.
Simplisticly put: because we prefer life over death.
You don't? You don't care about wether you live or die? You don't care about wheter your loved ones live or die? Do you only care because some bronze age book tells you that you should? Or would you care anyway - even if you stop believing in the book?
I agree with you that human morality is very real, but the question is: why is it...
Because we prefer life over death.
