They cannot handle immaterial concepts such as goodness, truth, justice, etc. because such concepts are not reducible to material components. They cannot abstract at all, because to abstract something is to consider it in a universal way, leaving the material parts behind. Computers are fundamentally material, and so cannot handle any kind of immaterial concepts.
