does evolution provide a moral basis for human behavior? i've been reading sartre go on about how if there is no god and no predetermined morality, then we create our own. and then today i saw this thread in which @xerx seemed to argue that evolutionary psychology discredited sex-positive feminism. and i was thinking about how science is replacing religion when it comes to understanding how the world works. and it seems like its taken for granted sometimes that if our behavior stems from biology, and is therefore natural, then its excusable or at least provides some kind of foundation for excusable behavior. but where does personal responsibility and free will come into play? what do you think?
i think @rat1 might have thoughts about this.
