In it, Haldane summarizes and critiques the current state of philosophy. He contends that the divorce between the the untrained thinker and the trained professional stems from the misguided understanding of the role and nature of philosophy. Specifically, it has become divorced from the interests and language of the naturally curious because it has neglected the issues of mind, soul, and God.

If nothing else, it explains why “possible world” modality may not actually be useful for describing and interpreting reality.
