 Another way to put this point is in terms of explanation. The monist can point out that the pluralist picture lacks explanatory depth. It seems that a list of values needs some further explanation: what makes these things values? (See Bradley, 2009, p.16). The monist picture is superior, because the monist can provide an explanation for the value of the (non-foundational) plurality of values: these things are values because they contribute to well-being, or pleasure, or whatever the foundational monist value is. (See also the discussion of this in the entry on   value theory).
