Interesting approach and it's an exercise that definitely offers you a greater perspective. However, I believe that categorizing itself is limiting, because adhering to categories offers a false sense of a global / objective perspective and creates a kind of a middle ground fallacy. These seven categories were picked by you and were influenced by your own personal experiences, beliefs and biases. For example, another person might never have picked "religious" and "occult" or even "ethical" since they are disciplines that depend on personal belief or opinion versus proven facts, but they might have picked "logic" or "semantics" or "evolutionary biology" or "anthropology" or "linguistics" and so on. I guess what I'm trying to say is that the categories themselves are constraining you inside your own biases, because they force you to choose which scope you believe is more important to examine things from. It's best to just be open and not categorize approaches. Just try to think critically and combine sources and knowledge.
