An Objective Morality for Secular Thinkers
"Evaluative concepts (e.g., “good,” “bad”) aren’t mystical or arbitrary—they are based on the fact that living organisms act to achieve goals in order to survive."
This is the fallacy of description vs prescription.
Observing how living organisms "act" is a description ("people are doing X"), but it does nothing to prescribe what anyone "should" be doing.
Survival and reproduction maximization is not a strategy anyone is "obligated" or "objectively" required to do.
Just finished reading the introduction. Lovely clear writing, there’s no doubt what you mean and no frustration so far getting what you mean. Good start!
