Chalmers on consciousness

Posted by

Chalmers asks why it is that we are conscious, and argues that a radical idea is required if we are to arrive at an explanation. Recent research has concentrated on searching for correlates of consciousness, such as brain regions that are active when consciousness is reported. However, such correlates are just things that coincide with consciousness rather than explanations. Emergence has also been seen as an explanation of consciousness, in the sense that hurricanes emerge from particular weather systems, and by analogy, consciousness emerges from neural systems and possibly also computer systems. However, Chalmers sees this as only explaining structure and behaviour rather than consciousness as such.

ON SPECIAL RELATIVITY Based on material from Roger Penrose and David Bohm While quantum theory and still more its implications have been censored out of much of popular thought and education, relativity may have had the opposite fate of being popularised as a wow! factor, with possibly a lack of balance as to what is really important about the theory. Mass-energy equivalence It could be argued that mass-energy equivalence is of greater significance than more crowd-stopping ideas such as Read more […]
