Krebs cycle is an eightfold cycle in one direction, oxidising, as in fueling the brain. This is the direction in which it could manifest consciousness.

Carboxylic acid expresses the twosome, as the oxygen connects two possibilities, the hydrogen and the carbon backbone of the molecule. The hydrogen can exist or not - opposites coexist - and the carbon based molecule which exists. I had in mind the structure {$C-O-H$} but a carboxylic acid has the structure {$O=C-O-H$} where the C is connected to the rest of the molecule. But note that actually the carboxylic anion (with an extra electron because the hydrogen is missing) has opposites coexist - there is an electron and a missing electron - whereas accepting a proton resolves this and we have all is the same, we have completion, determination, as to which oxygen is which.

Krebs cycle - do the tricarboxylic acids express triambiguity of operators +1, +2, +3? where the emphasis is on any one of the three carboxylic acids in a molecule?

The purpose of life is to hydrogenate carbon dioxide. {$CO_2$} becomes methane {$CH_4$}. (Is this relating the mind that knows and the mind that does not know?) The Krebs cycle is the low energy state for that. Is methane related to the eightsome?

• Methane is a tetrahedron!
• Methane burns: {$CH_4+O_2=CO_2+2H_2O$}.
• The reverse process is the hydrogenation of carbon dioxide: {$CO_2+2H_2O=CH_4+O_2$}

ATP is {$C_{10}H_{16}N_5O_{13}P_3$}. Hydrogen has 1, Carbon 6, Nitrogen 7, Oxygen 8, Phosphorus 15 protons. Thus the total number of protons in ATP is 60 + 16 + 35 + 104 + 45 = 260.

In the world of spiritual requirements for material implementations: Eightfold cycles for consciousness? Citric acid cycle | Citric acid cycle (Krebs cycle), Calvin cycle (photosynthesis). Compare with Glyoxylate cycle and Reverse Citric acid cycle (reverse Krebs cycle).

The Kreb cycle functions as a switch, turning forwards or backwards. Does one direction (energy?) represent the unconsious +1, the other direction (growth?) represent the conscious +2, with consciouness functioning as the switch? Can we foster alternation between stepping in and stepping out?

Think about characterizing the chemical soup in which interactions take place. There is the solvent (like water) and the solute forming a uniformly distributed solution. Can there be a gradient? Then pH is an important characteristic which can lead to an electric gradient if there is a boundary with a zone with a different charge or different pH.

Reproduction - replication - is a type of flow, recurring activity, a form of persistence in terms of flow rather than material

• (1) thermodynamic autonomy - isolated from disruptive environment, (2) persistence - the origin of purpose, (3) endogenous activity, (4) holistic integration, (5) low‐level indeterminacy, (6) multiple realisability, (7) historicity, (8) agent‐level normativity
• A scientific experiment eliminates noise which simplifies the analysis of causality but is unreal. Noise, as in John's dynamics, is normal.
• Causation is interpretative - looking for difference makers - neural populations do that. There can be multiple responsible parties but many of them are assumed and unexamined.
