I believe that the first step is to erase the 'vs' between the two.

My only objection to that point is the idea that statistical methods
are more efficient than knowledge-based systems. Efficiency always
depends on the specific problem that is being addressed at the moment. (04)
Following is a paper that discusses related issues -- especially the
point that there is *no limit* to the number and variety of reasoning
systems. Just look at the number of different ways of thinking by
different people -- or by the same person at different moments. (05)

I presented this paper at a conference in Poland. When I return next
week, I'll post the slides, which have more detail about some of the
issues. I quote the following point by Marvin Minsky in both: (07)

The major research issue is to understand the open-ended diversity.
The major obstacle is the claim that some single method is the
foundation for a GUT -- a Grand Unified Theory. (09)
