The Hard Problem of Consciousness

The problem deals with explaining why any physical state is conscious rather than non-conscious. Or how does material existence leads to awareness.

Spira proposes that, consciousness is that through which all experiences is known. This definition aims to invoke more than explain. Following it, it results consciousness transcends all mathematical descriptions, which Hoffman agrees with. 

But even though the proposal seems to be that consciousness is fundamental and we can never get to a math model for it, incomplete explanations may have value.
