  • John Searle argues that consciousness is a biological product of brain processes, requiring a rigorous scientific exploration of its mechanisms.
  • The distinction between syntax and semantics is crucial, as computers lack genuine comprehension, thus cannot possess true consciousness or motivation.

The Nature of Consciousness

Consciousness is fundamentally a biological product of brain processes, yet misunderstandings about its nature abound. Two prevalent traditions misinterpret consciousness: one views it through the lens of the soul and spirituality, while the other adopts a scientific materialism perspective that dismisses its significance. This dichotomy leads to the conclusion that consciousness cannot be fully integrated into scientific inquiry, either as a divine gift or as an inconsequential byproduct. The emerging view advocates for a scientific exploration of consciousness, recognizing its biological roots and the need for a rigorous investigation into its mechanisms.
