Hmm. That's an odd comment since we weren't talking about how brains work, but whatever. The brain is a biological neurological organ governed by chemical reactions whose modality is neuronic firing over synaptic linkages. Consciousness, however, is not a material presence in the brain, but rather a little-understood result of chemical and biological life functions. No one really understands how consciousness works or specifically how it is engendered. Memories, in contrast, seemed to be stored like data (our computers try to model the same type of processes), but all the technicalities of how memories are stored and retrieved is not totally understood either, since they are not like computer storage (memories can be faulty). Brain functions like emotions arise in certain parts of the brain as it works, but things like intuition (which some people have in spades and others not at all) are not completely or well understood either. All in all, our knowledge of the biological and chemical functions of the brain are decently understood, but functions of the brain such as consciousness, conscience, free will, and intuitions are not well understood at all. We are still on a learning curve for those.
Neuroscience is advancing rapidly. There are still wide disagreements about the nature of human nature (monism or dualism), physicalism as the explanation of all things, biological determinism, reductive materialism, and the emergent qualities of brain function and consciousness.
So saying, evidence of our consciousness and thoughts betrays that we are more than just physical objects. The brain evidences emergent qualities that cannot fully be explained by biological or chemical science. Since the brain is a complex dynamical system and not static, completely chemical explanations for self, consciousness, conscience, free will, and intuitions fall short of adequate. Thinking, deciding, consciousness, memory, language, representation, belief, etc. are large dynamic patterns of brain activity that constrain the ongoing lower-level physiological phenomena whose activity constitute the brain patterns themselves. Therefore the causal properties of patterns are not reducible to the elements. That's what I was talking about. The immaterial parts of our brain give evidence to the possibility of soul existence.
