Before Kuhn, most scientists followed the place-a-stone-in-the-bright-temple-of-knowledge tradition, and would have told you that they hoped, above all, to lay many of the bricks, perhaps even set the keystone, of truth's temple-the additive or meliorist model of scientific progress. Now most scientists of vision hope to foment revolution.
We are, therefore, awash in revolutions, most self-proclaimed.
