Abstract: This chapter summarizes the key ideas advanced in the book and offers positive motivation for Hypotheticalism. Some advantages of Hypotheticalism derive from the fact that it is a reductive theory of the normative. A second class of advantages derives from its treatment of the weight of reasons, which allows it an elegant diagnosis of data about the apparent holism of reasons and of Hume's Law. A third class of advantages derives from its treatment of moral motivation and moral epistemology. A highly general methodological argument is offered in favour of the Humean Theory very generally, of which Hypotheticalism purports to be the most defensible version. Finally, it is shown that the same sorts of problems that confront the Humean Theory can be raised for other theories as well, and argued that the tools that Hypotheticalism uses to answer these objections work better on its own behalf than on others'.
