A note on the Aristotelian origin of Popper's demarcation criterion together with its application to Atlantic Canada's fisheries

Abstract

It has not always been realised that Karl Popper's demarcation criterion, the criterion he uses to distinguish an empirical science from its 'metaphysical' complement involves an interpretation of the classical theory of terms. From the beginning Popper's criterion never was an attempt to distinguish some subject matter called 'science' from some subject matter called 'metaphysics'. His criterion of falsifiability always was an attempt to distinguish the logical strength of a universal law from the logical weakness of its complement, a complement that can bear no fruit. For example: if the falsifiability criterion is applied to the management of the fisheries of Atlantic Canada we can distinguish the bold and sound management of Atlantic lobster from the weak and unsound management of Atlantic groundfish. In the early 1990's Newfoundland's fishery for Atlantic cod suffered a major collapse that has become one of the world's most prominent case studies of failure in fisheries management. Under Popper's analytic theory of demarcation a weak management with no problem solving potentiality is to be held responsible for the collape of Newfoundland's Atlantic cod fishery.
