Episode notes
Kant's Phenomenal Noumenal Divide
- Immanuel Kant erected a strict epistemic divide between the phenomenal (sensation-based) world and the noumenal (metaphysical) world.
- Kant argued we can only scientifically investigate appearances, so essences, the self, and God lie beyond theoretical knowledge.
Essences Are Epistemically Unreachable
- Kant treats essences and substance as unknowable because we never have sensations of substratum; science cannot reach metaphysical essences.
- He remains agnostic about whether essences exist, insisting metaphysics becomes speculative when it tries to transcend sensations.
Self Is Not Theoretically Knowable
- Kant denies direct theoretical knowledge of the self, calling our awareness a 'transcendental apperception of the ego' that isn't a perceivable core self.
- He says Descartes' 'I think therefore I am' presumes a causal link without sensory evidence of the self's substance.
