We often think, naively, that missing data are the primary impediments
to intellectual progress -- just find the right facts and all problems
will dissipate. But barriers are often deeper and more abstract in
thought. We must have access to the right metaphor, not only the
requisite information. Revolutionary thinkers are not, primarily,
gatherers of facts, but weavers of new intellectual structures.
