Any “working definition” of morality must be based upon our relationships with one another and the wider world. Obviously, it’s not enough to define morality as referring simply to what is “right” or “good”. That just begs the question. Morality fundamentally has to do with wellbeing — human wellbeing in particular, though it’s not difficult to identify numerous moral problems involving other animals and the environment more generally. That said, we will typically find that excessive/unnecessary harm to other animals and/or to the environment will have negative consequences for our own wellbeing as well, if not immediately then down the road. Therefore, I find no problem with keeping human wellbeing at the center of any working definition of morality. So, in general, that which is “good” or “right” will tend to enhance our wellbeing and fulfillment as social creatures while that which isn’t will tend to harm it.
