The biggest problem with multiplying intelligences is that it opens the door for people to deflect criticisms on the basis that the critic simply lacks the appropriate one. “Spiritual intelligence”, for instance, cannot be a straightforward capacity since there is wide disagreement about what it means to be spiritual and whether all sorts of allegedly spiritual phenomena are real. Yet on some definitions, a materialist atheist would simply be spiritually thick. A substantive, contentious worldview can thus be disguised as an objective cognitive capacity. A clever move, but not one that can be described as truly intelligent.
