It's like asking, 'Where did the football game go?'. Information does not exist. It insists. Quantum Mechanics works because of the simplicity of the microcosm. The behaviors of atoms are extremely literal and discrete. As matter becomes more complex and multiply recapitulated (as chemistry, biology, zoology, neurology), the possibilities of 'information' acquire qualitative degrees of freedom - sensation, feeling, awareness, thought. Each perceptual frame evolves a new fundamental unit - the molecule, the cell, the body, the mind, which exists within it's own perceptual frame of reference with it's own rules which cannot be reduced to simpler levels.
