Hey Sam; thanks for the opportunity to interact with your views. If I understand The Moral Landscape correctly, your central thesis is that moral truth exists and can be scientifically understood. This seems to cash out in two critical claims:
I. Moral goodness, broadly speaking, just is whatever supports or increases the well-being of conscious minds;
II. Science, in principle if not always in practice, can discover facts around, make predictions about, and ultimately guide the process of promoting this collective well-being.
I know you’ve already faced a lot of criticism about (I) in particular, so I hope I won’t be beating a dead horse. I’m going to assume (I) for the sake of argument and agree with you: a person who denies that morality is about promoting well-being simply isn’t making sense. I hope to persuade you that your own moral beliefs actually reveal the opposite: it is the person who thinks that morality is about promoting well-being who isn’t making sense.
