 As an aside, note also that we have construed this method for understanding normativity in worldly, not conceptual terms. This is certainly one way of doing it, but it is also possible to replicate the strategy at the conceptual level. For example, one might propose a version of reasons fundamentalism according to which the concept &lt;reason&gt; is the normatively fundamental concept. Such a view would claim that the concept &lt;good&gt; can be analyzed in terms of the concept &lt;reason&gt;. A conceptual version of value fundamentalism would do the opposite.
