You have mentioned the reason in the following: some important knowledge is procedural by nature. > There is the idea of "deductive planning" which allows us to plan actions > using a solely declarative KB.

The knowledge about "how to do ..." can either be in procedural form, as "programs", or in declarative, as descriptions of the programs. There is overlapping/redundancy information in the two, but very often both are needed, and the redundancy is tolerated. > Even worse, in some cases you may only have procedural knowledge, without > anything declarative.
