 You can think of the philosophical methodology of providing analyses as a collection of attempts to formalize or partially formalize various common sense notions.  These attempts are far smaller in scale, less systematic, and more heterogeneous than the parallel effort that is emerging in AI.  Philosophers have never chosen a specific domain comparable to the planning domain and mounted a sustained attempt to formalize it, along with a companion effort to develop appropriate logics.  And no matter how complex the notions with which they which they are concerned, philosophers have never allowed their analyses to grow to the complexity where  methodological issues arise similar to those that apply to the development and maintenance of large software systems.
