Basically Harris exhausts his argument within the first 50 or so pages. It's very simple: we should make our decisions in utilitarian fashion (i.e. in such a way that maximises the happiness of society), and we will increasingly be able to use neuroscience to help us measure happiness. In this way, science can be used to answer moral questions.
I felt the rest of the book was simply padding. He gives examples and addresses counterarguments but it's not a particularly new way of thinking. Utilitarianism has been around for years - Harris is simply pointing out its practicability as science's capacity to quantify happiness improves.
