Intelligence is the ability to virtualize information. It is specific to living things. While consciousness is the principle of representation. Universal principle in reality.
The two are intimately linked. The strengthening of consciousness comes from its elevation on the levels of information constructed by matter, and then especially by neural networks. It is this upper part of the building that we call intelligence ’.
Complicated answer (for complexity specialists):
Intelligence and awareness are both the result of deepening integrated information. However intelligence is specific to neural networks and their ability to deepen information virtually, while consciousness is not the prerogative of the brain or even of living things. It is a more transcendental principle building reality.
What is integrated information? It is a collection of information, each element of which depends on the condition of the others. This whole, as an integration, represents an additional level of information. This representation is not an immaterial illusion, it is inscribed in reality. She herself becomes information from another level of reality formed by her fellows.
The independence of the representation is evidenced by the fact that different sets of information do not change the representation. The properties of representation, as an independent element, remain stable as its constitution evolves. The additional level of reality is rigorously ontological.
A changing constitution is transformed into a stable whole. "Transformed" is not the appropriate term because the whole does not replace its constituents; it is added to it, entangled. I use the term 'superimposed'.
It is in this representation, an ontological phenomenon, that consciousness is born. There is no need to add the slightest mysticism to it. Consciousness is basically the integration of a set of information into a fusional representation. It exactly matches our conscious experience.
But this is not a phenomenon unique to neurons. Matter is already building its levels of representation and therefore its superimposed layers of consciousness. Neurons add their own layers by virtualizing information. It is because of their special properties that the levels add up very quickly. It is not a question of the number of neurons but of the segmentation of the integrated information. Graph theory gives indications on this subject. Segmentation and depth of information correlate with the variety of signals processed and their regularities, rather than the number of neurons involved.
This explanation shows that some neural areas, like the cortex, build very high level consciousness, while others (the 'second' intestinal brain) do form one, but too frustrating for us to associate with it. our cortical consciousness.
Intelligence also becomes easy to explain. It does not vary according to the number of neurons (all brains have the same number of neurons, some have sometimes only 10% and develop normal intelligence). It varies according to the depth of information constructed in each area studied by neural networks.
Intelligence is the superimposition of a large number of levels of mental representation (of elementary consciousness) about a subject.
The stacking of levels of information is what I call the Diversium for physical reality (it is a process of deepening and diversifying information). The part of this stack formed by neural networks, i.e. the mind, is what I call the Stratium (strata of virtual information).
