To investigate whether the Keynesian paradigm is scientific we need a criterion for the scientificity of a paradigm. The paper first considers one approach to this problem due to Kant, but this is rejected as incorrect and called 'the Kantian fallacy'. Another approach is then put forward: 'the empirical confirmation principle', and reasons are given for accepting this as correct.
