The phrase "hard problem of consciousness" refers to the perplexing challenge of explaining subjective experience and consciousness. The word "hard" is spelled /hɑrd/, with the initial "h" sound pronounced as in "house." "Problem" is spelled /ˈprɑbləm/, with the accent on the first syllable and the "o" sound pronounced as in "hot." "Consciousness" is spelled /ˈkɑnʃəsnəs/, with emphasis on the second syllable and the "sh" sound pronounced as in "shoe." The spelling of this phrase accurately represents its pronunciation in English.
The hard problem of consciousness refers to the profound philosophical challenge of understanding the subjective experience or qualia associated with consciousness. It delves into the fundamental question of how and why certain physical processes give rise to conscious experience. Coined by philosopher David Chalmers, the hard problem specifically addresses the subjective nature of consciousness, distinct from its more easily explainable functional aspects.
This philosophical inquiry arises from the difficulty in bridging the gap between objective neurobiological processes and the phenomenal subjective experience of consciousness. While science can explain the neural correlates of consciousness, it struggles to account for why certain brain processes generate specific subjective experiences, like the sensation of color or taste.
The hard problem questions whether consciousness can be reducible to mechanistic or physical explanations or if it requires an entirely new form of explanation. It challenges our current understanding of the relationship between the physical and the mental realms.
Multiple philosophical theories and perspectives have been proposed to address the hard problem, ranging from panpsychism (the belief that consciousness is a fundamental property of the universe) to dualism (which posits the existence of both physical and non-physical aspects to consciousness). However, resolving the hard problem of consciousness remains a deeply contested and ongoing topic of philosophical debate.
