I would describe the &quot;revolution&quot; in the following sense. Workers were aware of both successes and failures of the classical model, and did want to throw the baby out with the bath water. They adopted as a ground rule, that any candidate for a new theory had to contain the old theory as a corner case.<p>Rather than describing a dichotomy between conservatism and revolution, I&#x27;d say that the revolutionaries searched for and found a hybrid of the two.<p>I also think that if any departure from steady-state is defined as a &quot;revolution,&quot; then it&#x27;s self fulfilling.
