Yes, enki, I read the Harris book when it came out, (I mean, 'The Moral Landscape'). One of its flaws surely, is that he assumes that happiness is the starting point, or the end-point of human existence. This itself is a subjectively chosen goal. In any case, I think there are many other human goals, e.g. control over others, dominance, power, survival, and so on.
I recall that Freud cited the pleasure principle, but interestingly, Freud also cited the death instinct, and many people have argued that as well as happiness, we are geared towards darker things. Certainly, some people want to be unhappy, and some crave destruction.
I don't see how all of this can be squeezed into objective morality.
