in the crystal, philosophy spans three domains:
spiri — meaning, values, ethics, aesthetics, transcendence, wisdom
meta — epistemology, knowledge theory, methodology, causation, truth
math — logic, propositional logic, predicate logic, modal logic, type theory
branches
metaphysics → meta + quantum (what exists, substance, identity, spacetime)
epistemology → meta (knowledge, justification, truth, belief)
ethics → spiri (ethics, moral reasoning, applied ethics)
logic → math (logic, formal systems, validity, Kurt Goedel)
aesthetics → spiri (aesthetics, beauty, art, music)
philosophy of mind → neuro + sense (consciousness, qualia, intentionality)
philosophy of science → meta (methodology, falsification, paradigms)
political philosophy → socio (governance, justice, sovereignty, rights)
