I will argue that consciousness is not a thing. “Consciousness” is the word we use to describe the subjective feeling of a number of instincts and/or… - Michael S. Gazzaniga

There obviously is a different feel to a wave of intense emotion versus an abstract thought, but each conscious form is an experience that gives us a unique perception of reality. The pattern in which these various conscious forms come in and out of awareness gives us our own personal life story. The vast variety of conscious forms and the ubiquity of consciousness in the brain are best explained by a modular architecture of the brain. The conceptual challenge now is to understand how hundreds, if not thousands, of modules, embedded in a layered architecture — each layer of which can produce a form of consciousness — give us a single, unified life experience at any given moment that seems to flow flawlessly into the next across time.

Recently scientists have found that cephalopods (the family that contains the octopus) can recode their RNA. RNA molecules have the privilege of establishing codes with DNA (in the part of the RNA that recognizes the three-nucleotide DNA codon sequence) and also with proteins (in the separate part of the RNA that recognizes the amino acid). Recoding the RNA means that new proteins can be constructed while the DNA sequence of symbols stays the same. The collective result is the destruction of the one-to-one gene-to-protein correspondence. Recoding allows a single octopus gene to produce many different types of proteins from the same DNA sequence.18 This is a big deal. It is evidence against the three concepts in biology that dismiss semiotic systems in living organisms. The system can change its code. The system has an internal codemaker that can produce biological innovations — new proteins — but not via natural selection. It illustrates the arbitrariness of the connection of a symbol with its meaning in a living system. If symbols within living systems

My mind takes flight like a butterfly. There is so much to do. You can wander off in space or in time, set out for Tierra del Fuego or for King Midas’s court. You can visit the woman you love, slide down beside her and stroke her still-sleeping face. You can build castles in Spain, steal the Golden Fleece, discover Atlantis, realize your childhood dreams and adult ambitions.
