The Experience Recorder and Reproducer
What is the minimal mind model that a primitive organism needs to process the information needed for biosemiotic interpretant power?
The neuroscientist Donald Hebb said in 1949 that
Information philosopher Bob Doyle suggests that The ERR Recorder: Neurons become wired together (strengthening their synaptic connections to other neurons) during an organism’s experiences, across multiple sensory and limbic systems. The ERR Reproducer: Later firing of even a part of the previously wired neurons can stimulate firing of all or part of many original complexes, thus "playing back" the original experiences (including the very important emotional reactions to the original experiences) producing William James’ “blooming, buzzing, confusion.” Man is not a machine. And the mind is not a computer. The ERR model stands in contrast to the popular cognitive science or “computational” model of a mind as a digital computer with a "central processor" or even many "parallel processors." No algorithms or stored programs are needed for the ERR model. There is nothing comparable to the addresses and data buses used to store and retrieve information in a digital computer. The mind is a biological information processor.
The ERR and Consciousness
At a conference on Free Will in Barcelona in 2010, Martin Heisenberg asked if I could develop proposals for evolutionary steps between his
bacterial level and the human levels of free will. I decided to regard them as levels of consciousness about experiences in
the Experience Recorder and Reproducer
Instinctive Consciousness - by animals with little or no
learning capability. Automatic reactions to environmental conditions are transmitted genetically. Information about past experiences (by prior generations of the organism) is only present implicitly
in the inherited reactions. (Konrad Lorenz- “What’s a priori in the phenotype was a posteriori in the genotype.”)
Learned Consciousness - for animals whose past experiences guide current choices (along with inherited experience). Conscious, but mostly habitual, reactions are developed through experience, including instruction by parents and peers. Predictive Consciousness - A sequencer in the ERR system can play back beyond the current situation, allowing the organism to use imagination and foresight to evaluate the future consequences of its possible choices. Reflective (Normative) Consciousness– in which conscious deliberation about individual values and the shared values of the species influences the choice of alternative behaviors.
The Two-Stage Model of Free Will
If we are determined, we are not free.
Philosophers Think Free Will Acts at a Moment
The Temporal Sequence of first Free, then Will
Most philosophers and scientists are compatibilists, who want their actions to be caused by their reasons, motives, feelings, etc. and not be random. They think free will is compatible with determinism. In the two-stage model, ontological chance or indeterminism of quantum mechanics is limited to the free generation of alternative possibilities. In the second stage, the evaluation of alternatives is an adequately (statistically) determined process that leads to a willed act of self-determination. This should be all that a compatibilist could want. It adds the fact that our actions are not pre-determined from moments before the decision process begins.
Downward Causation
Is it illogical to claim that biological information processing systems can have one-way causality?
The philosopher of mind Jaegwon Kim claims that the physical world is "causally closed," that the mind is epiphenomenal, that every mental event has a corresponding physical event that is the efficient cause of our actions. Mental events are redundant! A study of the behavior of atoms and molecules in ribosomes in normal cells and in ion channels in neurons shows that semiotic information control flows only downward at the biological/chemical and mental/biological interfaces. The lower level atoms and molecules are shown to be in thermal equilibrium. Their paths do not contain the information (Gibbs/Boltzmann “molecular order”) that would be needed for lower levels to be “in charge” of the upper levels. The intuitions of the emergentists are confirmed that biology cannot be reduced to chemistry and physics, nor can mind be reduced to the brain/body. Biosemiotic control has one-way causality.
A Ribosome at the Biology/Matter Boundary
The twenty amino acids move about randomly in a cell, the consequence of thermal and quantum noise. Attached to them are tiny bits of transfer RNA, each with three letters of the genetic code that identify them. They bump randomly into the ribosome, which may be moving along a sequence of the genetic code written in the messenger RNA sent from the cell nucleus, signaling that more of a specific protein or enzyme is needed. The random motion shows us that no organized or coherent information is present in the unattached tRNAs that could cause something from the bottom up to control the higher level. Notice the absurdity of the idea that the random motions of the transfer RNA molecules (green in the video), each holding a single amino acid (red), are carrying the pre-determined information about where they belong in the protein. Reductionism is nonsense. It is the information processing of the higher-level ribosome that is in control. As the ribosome moves along the string of mRNA, it reads the next three-letter codon and waits for a tRNA with the matching anti-codon to collide randomly. With over 60 codons for the 20 amino acids, it might be some time before the desired amino acid shows up. Note that it is the high speed of the random thermal motions that allows this process to proceed rapidly.
An Ion Pump at the Mind/Brain Boundary
When a single neuron fires, the active potential rapidly changes the concentration of sodium (Na+) ions inside the cell and potassium (K+) ions outside the cell. Within milliseconds, thousands of sodium-potassium ion transporters in the thin lipid bilayer of the cell wall must move billions of those ions, two or three at a time between inside and outside the cell wall, to get the neuron ready to fire again. All the individual ions, atoms, and molecules in the cell are moving rapidly in random directions. The indeterministic motions of the ions randomly move some near the pump opening, where quantum collaborative forces can capture them in a lock-and-key structure. The idea that the physical/chemical base level contains enough information in the motion of its atoms and molecules to cause and explain the operations of the higher levels of life and mind is simply absurd. The emergent biology of a sodium-potassium pump exerts downward causation on the ions, powered by ATP energy carriers (feeding on negative entropy). The sodium-potassium pump in our neurons is as close to a Maxwell’s Demon as anything we are ever likely to see.
Biological Information Processing Turns Matter Into Life
When a ribosome assembles 330 amino acids in four symmetric polypeptide chains (globins), each globin traps an iron atom in a heme group at the center to form the hemoglobin protein. This is downward causal control of the amino acids, the heme groups, and the iron atoms by the ribosome. The ribosome is an example of Erwin Schrödinger's emergent "order out of order," life "feeding on the negative entropy" of digested food. The random motions of the molecules in the cytosol insure that there is no organized "bottom-up" causation directing the ribosome. Notice the absurdity of the idea that the random motions of the transfer RNA molecules (green in the video at right), each holding a single amino acid (red), are carrying pre-determined information of where they belong in the protein.
![]() When 200 million of the 25 trillion red blood cells in the human body die each second, 100 million new hemoglobins must be assembled in each of 200 million new blood cells . With the order of a few thousand bytes of information in each hemoglobin, this is 10 thousand x 100 million x 200 million = 2 x 1020 bits of information per second, a million times more information processing than today's fastest computer CPU. The ribosome is an information-processing biological system that has emerged from the lower level of chemistry and physics to exert downward causation on the atomic and molecular components needed to manufacture hemoglobin.
Claude Shannon's Communication of Information
![]()
Roman Jakobson's Communications Functions
![]() Jakobson's work on communications functions appeared in Thomas Sebeok's 1960 book, Style in Language. Writing about ten years after Claude Shannon, and making no specific reference to his theory of the communication of information, Jakobson's diagrams clearly reflect Shannon's influence. Jakobson distinguished six communication functions, each associated with a dimension or factor of the communication process. Context was perhaps Jakobson's most important addition to semiotics. Adding context gives us the difference between semantics (the standard dictionary meaning of a word according to the normal "rules" of the language) versus pragmatics, the meaning that may be intended by the sender, or should be inferred by the receiver/interpreter because of the current situation. Jakobson calls this contextual information "denotative," "cognitive," "referential," the "leading task" of a message. Context-dependence alters the "meaning" to suit the purpose of a communication.Notes:
Jakobson's famous but mysterious dictum "the poetic function projects the principle of equivalence from the axis of selection to the axis of combination" presages the fall of Saussure's synchronic, time-independent structuralism to the post-structuralist and post-modernist diachronic view, notably Jacques Derrida's "différance" whose meaning of deferral can only be seen and not heard, to displace the Platonic privileging of voice over text. Derrida showed that meaning is deferred, disseminated, that Saussure's claim that meaning is "différence" is not the whole story. And Roland Barthes showed the dyadic Saussurean s/S becomes the "circle of signifiers" s/Z if one is trapped in Jakobson's "selection axis" of looking up words in a dictionary of dead (non-evolving) languages.
Umberto Eco's Communications Model
![]() In his book, A Theory of Semiotics, written between 1967 and 1974, Umberto Eco rewrote the "usual communications model" as above (p.141), with strong influences from Claude Shannon and possibly Roman Jakobson. He wrote: The information of the message is only reduced by the addressee when he selects a definite interpretation.He also wrote a paradoxical example of the problem facing the interpretant: i vitelli dei romani sono belli

Concepts and Percepts (without Objects)
Immanuel Kant wrote this famous chiasmos (figure of speech) Gedanken ohne Inhalt sind leer.
Charles Sanders Peirce adapted this for a beautifully symmetric chiasmos about the fundamental dualism. If Materialism without Idealism is blind, With a nod to Kant and Peirce, we can say Kantcepts without Peircepts are empty. And although Freedom and Values are not a dualism, they too require one another and we can observe, Freedom without Values is Absurd (Continental Existentialism).
