Dualism is a theory that states that the mind and the body are two separate entities, with qualia being non-physical properties of the mind.

The Identity Theory states that qualia are identical to brain states, meaning that there is no distinction between the subjective experience of a quality and the physical processes in the brain that give rise to it.

The Qualia Problem encompasses several challenges, including explaining the relationship between qualia and brain states, defining qualia in objective terms, and measuring qualia scientifically.

Panpsychism is a theory that states that consciousness is a fundamental property of the universe, and that qualia are properties of the entire universe, not just of individual minds.

The Explanatory Gap Argument argues that physical explanations cannot fully account for the subjective experience of qualia, that qualia are non-physical and therefore cannot be explained by physical theories, and that physical theories are incomplete and cannot fully explain consciousness.

Emergentism is a theory that states that qualia are emergent properties of complex systems, such as the brain, and that they cannot be reduced to the properties of the individual components of the system.

The Hard Problem of Consciousness, as defined by David Chalmers, refers to the question of why qualia exist at all, and why they are associated with certain physical processes in the brain.

Naive Realism is a theory that states that qualia are identical to the properties of objects in the external world, and that these properties exist independently of our perception of them.

The Representational Theory of Qualia states that qualia are mental representations of external stimuli, and that these representations are what give rise to our subjective experience of sensory qualities.

The Phenomenal Concept Strategy is an argument against Physicalism, specifically against the claim that physical properties are all that exist.

The Mental State Theory states that qualia are properties of mental states, and that they are not reducible to physical properties or brain states.

The Qualia Inversion Argument is an argument against Physicalism, specifically against the claim that qualia are identical to brain states.

The Knowledge Argument argues that qualia are unknowable in principle, meaning that it is impossible for us to fully understand or explain the subjective experience of sensory qualities.

The Relational Theory states that qualia are properties of the relationship between the mind and the body, and that they cannot be reduced to either physical or mental properties alone.

The Mysterian Theory of Qualia claims that qualia are unknowable in principle, that they are non-physical and therefore cannot be known, and that they are too complex to be fully understood.
