Is consciousness biological?

My answer to the question of consciousness being biological is that it is not biological. There are no proofs nor adequate concepts that the mind can produce to verify this position. Language is based on understanding and experience both collectively and individually which does not have a vocabulary adequate to reduce the question of consciousness down to that which the mind or intellect can grasp.

Are there other tools or sources of knowing than the intellect that can address this issue?

Many say there are. These are primarily "Eastern" Sages who claim an intuitive, apperceptive, re-cognitional, "knowing" that happens when Consciousness awakens to a recognition of itself. These words, however are all loaded with interpretations, connotations, and other mind functions that can never communicate rationally or with any intellectual reliability a satisfactory "understanding" of Consciousness.

The general consensus view is that consciousness is a kind of sub-function of the brain. Thus, making consciousness a kind of by product of biological brain activity. This suggests that the biological brain is prior to consciosness. Consider the possiblity that the reverse is more valid. That Consciousness is prior to the mind or brain activity. Again, this cannot be rationally or logically verified because that, itself, is an activity of the brain.

There are many who have "re-cognized" that what we call reality is nothing but Consciousness. They also recognize that for purposes of communication that Counsciousness must be understood on two "levels" Some call these Noumenal Consciousness (without form or content) and Phenomenal Consciousness which is formless, infinite, boundless, non-local, and impossible to define.
