Wrapping up Rethinking the Keynesian Revolution

Here is part of Goodspeed's last paragraph:
But, more than that, so polemics surrounding the "Keynes versus Hayek" debate have tended to obfuscate the very issues at which both economists were driving. For both economists, as for Wicksell before them, the concept of equilibrium was useful not as the description any actual terminal state, but rather as an analytical stepping stone toward explaining economic dynamics outside of equilibrium, given that in any real-world historical process, disequilibrium, particularly of the intertemporal variety, is the rule rather than the exception. -- p. 16
