What is Consciousness?

The difficult definition

Consciousness −etymologically "to know together"− is very difficult to explain because we do not know exactly what it is, even though we all claim to have it. In fact, it is often considered to be such a mysterious and complex subject that it requires a multidisciplinary effort by generalists and specialists, by philosophers, neuroscientists, physicists, biologists, psychologists, linguists, mathematicians, computer scientists, systematists, etc. The subject of consciousness is often equated with the subject of life, since both constitute a mystery for science.

Today we are witnessing a renewed interest in the investigation of the consciousness, which is manifested in conferences, associations, research centers, specialized journals, books, etc. The problem of the consciousness is considered "the last great frontier of science", according to the organizers of the Conference "Towards a Science of Consciousness" (Tucson IV, 2000). Consciousness, indeed, is the key, the "Holy Grail of science", since the understanding of consciousness would open the doors to everything else, since it is believed that consciousness is the foundation of everything.

Throughout history there have been numerous attempts to explain consciousness, but none of them has provided a sufficiently satisfactory answer. It has even been suggested that the problem may be intractable for three reasons:
  1. The scientific method cannot be applied because it presupposes an independent observer. And in the case of consciousness we cannot separate subject and object, since we play the role of observer and observed. Moreover, we cannot observe our consciousness without affecting it.

  2. Consciousness is a subjective experience. It is not possible to objectify that experience so that it can be shared. It belongs to an internal world only accessible to the person who experiences it. This experience cannot be reduced to the concepts of physics because it is an internal world, a world different from the external world. It is thus a challenge to physicalism, the idea that all phenomena are physical.

  3. Internal experiences are of a qualitative type, as opposed to external phenomena, which are of a quantitative type. Subjective qualities of conscious experience, such as smelling a rose, feeling the color red, experiencing pain, etc., are called qualia (plural of the Latin term quale). Qualia constitute the central question of the problem of consciousness. In an attempt to express or model qualia objectively, somewhat complex alternatives have been proposed, such as nonlinear chaotic dynamics, indeterministic processes, superposition of quantum states, and so on. But qualia cannot be reduced to physical phenomena, however sophisticated they may be.

    The term "qualia" was coined by medieval scholastic philosophers and first used modernly in the philosophy of Clarence Irving Lewis.
Some opinions in this regard are:
The Multiple Visions of Consciousness

Given the multidisplinary character of the problem of consciousness, it has been interpreted from the points of view of different fields, and there are a great number of opinions that help us to approach it, even if only intuitively:


Psicology
Biology
Mathematics
Philosophy
Linguistics
Information and computer theory
Systemics
Holismo
Neuroscience

The current paradigm in neuroscience is what is called "biological naturalism," which defends the biological character of mind and consciousness. Consciousness is the result of the extraordinary complexity of the brain. Consciousness and mind are epiphenomena of the brain, i.e., consciousness is a neural correlate. Therefore, the mind-body connection is one-way. What is difficult to explain is the mechanism of emergence of consciousness and qualia from neural networks.
Quantum physics

The subject of consciousness has been related to the deep level of matter, to the quantum level, where matter is blurred.
Metaphysics, spiritualism and universalism

Addendum

East vs. West on the subject of consciousness

There is currently some disagreement among psychologists on how to harmonize Eastern and Western conceptions of consciousness: Individuation and enlightenment are distinct processes. Individuation is an integrative process. Enlightenment is a process of liberation and connection with the higher, the unlimited and unmanifest, where the unity of all things is contemplated.


Biocentrism

Biocentrism is a "theory of everything" proposed by Robert Lanza [2012], a scientist in the field of regenerative medicine. Biocentrism is based on considering life and consciousness as the foundation of the physical world: This conception is similar to the anthropic principle: the universe exists so that human life can exist. A slight modification of one of the fundamental constants of physics would make human life impossible. It also fits with John Wheeler's theory of the participatory universe, a version of the anthropic principle in which observers are necessary for the universe to exist.

Biocentrism has received criticism:
Mary's room

Mary's Room is a philosophical experiment proposed by Frank Jackson in his article "Epiphenomenal Qualia" [1982] and expanded in "What Mary Didn't Know" [1986] in which he attempts to disprove the theory that all knowledge is of a physical kind. For Jackson, Mary gains new knowledge that is mental, not physical. Therefore, not all knowledge comes from the physical world, qualia exist, they are real mental properties. And physicalism (the idea that all phenomena in the universe are of a physical kind) is false.
