In this Article, Professor Lipkin continues the debate over the nature
of indeterminacy in constitutional theory, arguing that epistemic ind
eterminacy is most relevant to the law, because epistemic indeterminac
y is more closely tied to practical reasoning than is metaphysical ind
eterminacy. Professor Lipkin further argues that the controversy over
metaphysical or epistemic indeterminacy is really a controversy over t
ruth or justification as the primary form of validating constitutional
rules. In Professor Lipkin's view, the search for constitutional trut
h should be abandoned or, at best, should be treated as a trivial resu
lt of the best justification. Finally, Professor Lipkin proposes a new
constitutional paradigm, integrating a revised version of Rawls's con
ception of wide reflective equilibrium with a modified account of Kuhn
's theory of scientific change that takes into account the distinction
between normal and revolutionary adjudication. Such a paradigm, Profe
ssor Lipkin argues, provides an interesting and complete account of co
nstitutional adjudication and change, and therefore is an especially a
ppropriate vehicle to transport constitutional theory into the twenty-
first century.
