AbstractSeveral authors have recently argued that knowledge is not the aim of inquiry since it can make sense to inquire into a question even though one knows the answer. I argue that this a faulty diagnostic for determining whether one has met the constitutive standard of success of an activity type. The constitutive standards of success tell us when an activity is successful, but such standards can be exceeded and exceeding them can be reasonable. To back this up I develop an account of zetetic supererogation and argue that subjects who continue to inquire into a question while knowing the answer do what is zetetically supererogatory.
