I can’t believe you guys are still arguing this same thing two pages later. Phoneutria is right but Carpophorous isn’t wrong wrong… just wrong.
There is some confusion regarding the meaning and use of the word ‘value’ here that is subtle and makes for long two page disagreements on how the word can be used.
Of course Carpo you could say that if a human being is adept at being P, living way X and doing Y things, and doing these things are good, then a fit human would the one who is P, lives way X and does Y things. A perfectly legal use of the word and concept ‘value’, but it isn’t purely scientific… as what Phoneutria is trying to explain.
It is easy to accidentally anthropomophize the concept of natural selection and evolution and see it as a process that is ascending or progressing. But in nature, concepts like ascending and progressing don’t exist. Change and repetition is permanent and the whole system isn’t getting ‘better’ or ‘worse’, only different.
That aside, human beings should (I’m sure Phoneutria agrees) anthropomorphize evolution, decide on an ideal type of human being, and try to realize it. That’s what intelligent human beings do; they value a certain kind of person and certain kind of behavior and want to make more of it while discouraging the other certain kinds of people and behaviors. The difficult part is justifying or supporting your reasons ‘philosophically’.
You two aren’t really disagreeing. This whole thing is about a misunderstanding. Any possible objective value judgements in evolution, whatever they are, are going to be about adaptability, life span and breeding success.
Anything else is a human, aesthetic or functional addition… not a fundamental requirement.
A colony of super huge mondo fat space people all hooked up to a machine that keeps them alive for thousands of years in coma induced virtual SIMS like worlds would be far more fit than you and I could ever be.
But we don’t like that. We’re going to step in and say those super huge mondo fat space people are disgusting because they can’t walk or work or anything. Ah, but walking and working are not necessarily required to be ‘fit’ in the strictest, scientific sense of the word in evolutionary theory.
If an environment can be manipulated by an intelligent creature this can fundamentally change the usual forces that move natural selection along, but it does not change the definition of ‘fit’. A human who has fifty percent less muscle mass would not be unfit in a artificial low gravity environment. So, to be fit would mean to be a skinny bastard able to flourish in this environment.
This is what Phoneutria is saying when she emphasizes the immediate circumstances, the ‘here and now’ at time X in environment Y. The definition of fit will always be: that organism in a specific environment that meets the requirements to able to survive and reproduce at time X.
