This thought-provoking book summary will spark your curiosity and challenge your beliefs about the nature of consciousness and its relationship to the physical world.

Unveiling the Mystery of Consciousness

Consciousness is a mysterious and fundamental aspect of life that is yet to be fully understood. Although philosophers have rarely attempted to explain it, consciousness is undeniable and essential to human existence. Consciousness is not physical; hence, materialism or physicality cannot explain it. However, any explanation of consciousness must align with neurological and other natural sciences. A hypothesis that aims to explain consciousness should clarify the conditions that trigger physical processes to create consciousness and specify what kind of experience is associated with consciousness. The theory should also elucidate how consciousness emerges in a way that is intelligible rather than magical. Consciousness is both phenomenal and psychological and requires the discovery of new “psychophysical” laws. Conscious experience is the most familiar but also the most perplexing aspect of life. Despite its elusive nature, further studies could help unravel the mystery of consciousness.

The Nature of Consciousness

Consciousness is an intense, real, and subjective experience that includes emotions, perceptions, and states of mind. It involves visual, auditory, tactile, and olfactory sensations, as well as thoughts, emotions, and the sense of self. Science struggles to explain why conscious experiences have their particular qualities or subjective feelings, and why conscious systems even have experiences to begin with. Consciousness has a dual character, phenomenal and psychological, and is not the only experience in the mind. Mental activities can be unconscious, although René Descartes believed otherwise. The relationship between consciousness and cognition lies in phenomenal judgments, and mental functionalists try to explain mental states through a cause-effect approach. However, some conscious experiences cannot be explained by behavioral dispositions or functionalists, which suggests that conscious experience may be an exception to the logical supervenience of physical facts.

Psychology and Phenomenology

The mind is made up of only psychological and phenomenal dimensions. Pain, for example, is a combination of both. Learning and memory, on the other hand, are mainly psychological. Emotions, such as happiness and sadness, have a significant phenomenal dimension. While science can describe psychological properties, it lacks a language for phenomenal experiences. While physical and psychological properties cannot explain consciousness completely, understanding both dimensions is necessary to understand pain and emotions.

Understanding the Complexities of Supervenience

This passage discusses the concept of supervenience, which is a relationship between properties or sets of properties. It explains that supervenience can be local or global, and differentiates between natural and logical supervenience. The article provides examples of supervenience, including how shape and color supervene on physical properties. Value, however, does not supervene on physical properties. The text argues that this failure of materialism leads to a kind of dualism: there are both physical and nonphysical features of the world. Additionally, The article explains logical supervenience through examples and explains it’s stronger than natural supervenience. The passage concludes that supervenience is an abstract concept that is useful in understanding the relationship between different sets of properties.
