Invariances: The structure of the objective world

Philosophy begins in wonder. It never ends.

[Moral] intuitions would fit the earlier social situations of people in hunter-gatherer societies, that is, the social conditions in which the evolutionary selection that shaped our current intuitions took place. (Would justifying norms by such intuitions make them relative to the conditions of hunter-gatherer societies?) How much weight should be placed upon such intuitions? Since they were instilled as surrogates for inclusive fitness, being correlated with it, why not now go directly to calculations of inclusive fitness itself? Or why not, instead, calculate what intuitions would be installed by an evolutionary process that operated over a longer period in which current social conditions held sway, and then justify our moral beliefs by their confluence with / those/ (hypothetical) intuitions, ones better suited to our current situation than the intuitions we have inherited? Or why stay with intuitions instilled by evolution rather than ones instilled by cultural processes, or by some other process we currently find attractive? (But what is the basis of our finding it attractive?)
