 The relatively permissive epistemological view of a constructive empiricist who is also an epistemic voluntarist helps explain why such a constructive empiricist would be prudent not to take constructive empiricism to be a normative theory concerning the deliverances of science. Mistakenly understood in that normative way, constructive empiricism would imply that belief in a theory’s empirical adequacy is the only rational candidate for the belief involved in a theory’s acceptance. Such a constraint on the rationality of opinion is clearly at odds with any epistemic voluntarism the constructive empiricist might embrace.
