Adopting an evolutionary lens: an optimistic approach to discovering strength in nursing

Appropriately, the state of the art of nursing is in constant review. Philosophy of science, particularly the work of Thomas Kuhn, has traditionally provided the criteria upon which these introspective evaluative processes are based. More recent developments in philosophy of science have introduced alternative models, such as Toulmin's evolutionary model, which might yield a more cogent, optimistic assessment of theoretical progress within nursing. Specific shortcomings of Kuhn's model and possible advantages of one evolutionary model are explored with comparative outcomes presented. Evidence of emerging evaluative criteria within nursing is also explicated.
