Hard Problem metaphors
The Hard Problem of consciousness is a philosophical mystery in the field of artificial intelligence that deals with a seemingly fundamental aspect of consciousness, namely the irreducible aspect of awareness known as qualia.
Philosophers and scientists have tried to solve the problem by adding additional complexity, or by reducing or denying the existence of the problem at all[1], or by minimizing its importance.[2][3] The mind could be seen as just a "black box" linking the senses and the muscles.
By the late 2010s, proposed explanations for the essential mystery of awareness remain incomplete, often using vague metaphors that could be seen as possible steps in the direction of an answer (if that) rather than an answer itself. If or when a genuine theory of awareness is developed, these metaphors may become obsolete and unnecessary. It's also possible all current awareness metaphors are completely wrong.[4]

Awareness metaphors
Quantity is quality
An immense amount of signals are exchanged every second in the human brain, more than in any supercomputer. This information is also more organized and integrated[5] than in any human-built computer. The subjective strangeness of awareness is fully equivalent to this immense complexity. The quality of awareness represents a vast quantity of knowledge. This organized complexity could be seen as a neural correlate of consciousness. The perception of reality is no more complex than the sum of what could be described about it in words, given enough time. Someone could spend years describing every aspect of their life, but their awareness could represent this complexity instantaneously. This is related to Strong Reductionism.
Strong Reductionism
The existence of awareness is no stranger than the existence of any object. The same basic essence underlies both matter and information. Matter IS information.[6] The actions that matter performs in the physical universe are just as complex as the perception and understanding of these actions. This is related to Transparency theory.
Transparency theory
When thinking about something, a mind only perceives a detailed representation of that thing, not some extra qualia or additional mental properties.[7] Qualia are artifacts that only exist when they are specifically being considered. This could be an aspect of Panpsychism.
Panpsychism
All information has a qualia-like aspect, but some qualia are more elaborate and therefore more intense than others. Everything physical has an underlying phenomenal nature. Full awareness involves the most detailed or elaborate qualia. These combine and organize the output of many lower qualia in the mind and the environment.[8]
Awareness is tautological
To be aware, a mind must create an elaborate and constantly updated description of its reality (which could be seen as the mind's focus). This model may be wrong or incomplete, but it will necessarily appear as the highest truth to the mind creating it, since no other truth is available to it.[9]
Experiencing is reliving
According to this theory, awareness is a function of the procedural memory. The current awareness of carrying out an often repeated action is immediately merged in the memory with all the previous times that that action has been carried out.[10]
This may also be a case of shared awareness.
Awareness is reverse memory
Emotions and feelings are undefined knowledge, a distinct sense of something that could only be described in words with a great deal of effort or not at all - for example the reason for a phobia. Emotions somehow describe these logical concepts before they have been logically defined. However, they may be imprecise and unreliable.
This is known as first-order representationalism. Conscious states attempt to present elements of reality "nonconceptually", even if the mind lacks the mental concepts to rationally categorize or describe them, as happens in intuition.[11]
In the theory of Neural Darwinism,[12] awareness combines direct perceptions and memories to create more elaborate but loosely defined higher perceptions about reality. It does this through neural reentry. The purpose is to prepare for the future, aiding the organism's and hence the mind's survival.
Awareness is false memory
While a mind can remember being aware in the past, awareness doesn't actually exist at any single moment in time, which is infinitesimal.
The perception that perception is inexplicable could itself be a mental simplification.[13] Perceptions of the past self are unreliable, as described in the multiple drafts model. This concept is part of Gerald Edelman's 1989 book about consciousness, "The Remembered Present".[14]
Both the external world and the past self are represented as something fundamentally different from the present self, which is the only version of the self which is undeniably aware (an extreme version would be momentary solipsism[15]). This may be related to the illusion of time passing and the paradox of free will.
Awareness is the illusion of freedom
Minds have no control over past actions or events. The freedom to act in the present (or free will) is pre-determined by the past self.[16] Philosophically, this is known as the argument from free will. Many neuroscience of free will experiments suggest that introspections about the reasons for an action are mostly illusions created after the fact.
Awareness is a self representational loop
Awareness may be fundamentally illogical. Every element is defined in terms of other elements. Such a recursive string of definitions may loop back on itself, creating the perceived self as a type of bootstrap model.[17]
Mind layers
Damasio's theory of consciousness and other higher-order theories of consciousness state that the mind is composed of many automatic response systems that are themselves not conscious. These are correlated, controlled, and manipulated by increasingly abstract control layers, that manipulate systems on the next lower layer. At the top (or the third layer according to Damasio) is abstract thought and planning, which is only partially aware of the lower layers and separate from them, but uses their results. It may do this through the mind's global workspace.[18]
Integrated information theory
A mathematical theory about the degree to which information can be organized in a finite system.[19] Awareness begins as a basic mind function that drives higher thoughts, and cannot exist separately from them. Awareness becomes stronger the more integrated a mind becomes, but may decrease again if the mind becomes over-organized.
Enactive or embodied awareness theory
Mental processes don't only depend on inner representations. Awareness is a dynamic process, with essential information being stored in the surrounding environment. Consciousness is a physical action, the brain interacting with the body and the world. A brain in a vat would be fundamentally less aware than a brain in a body.[20][21]
Universal Improver
A hypothetical computer program that could take any true statement, and change it into a different statement that would also be true, while adding insight about the original statement. The new statement could be shorter, by organizing or compressing the original statement; or it could be longer, elaborating and explaining the original statement. Any software consistently capable of doing this might have to be as complex as a conscious mind.
