Do you still think it has merit? I would be curious to know what parts of it you think are worth adopting (or have been) into modern theories. Personally I'd love to see more research go into forms of symbolic AI that can deal with uncertainty, probability, partiality etc. The Research VP of Cycorp told me he wanted to go in that direction with Cyc, but couldn't find anyone with a promising and rigorous proposal. I think those sorts of considerations often lead either to pure theory with no thought to implementation, or the worst kind of adhoc "fuzzy logic" (scare quotes because fuzzy logic is a proper mathematical discipline).
