Understanding this quote
What it means
Consciousness—why subjective experience exists at all—resists explanation even when we fully map the brain's physical processes. Knowing how neurons fire doesn't explain why there's something it feels like to see red or feel pain. This quote acknowledges that some questions exceed current analytical frameworks. Rather than paper over genuine ignorance with confident speculation, the speaker admits the problem is real, deep, and unresolved—intellectual honesty over false authority.
Relevance to Alan Turing
Turing's 1950 paper 'Computing Machinery and Intelligence' proposed the imitation game precisely to sidestep consciousness—testing behavior rather than inner experience because he knew subjective questions couldn't be resolved by logic alone. He built machines that computed but never claimed they felt. Prosecuted and chemically castrated for his sexuality, Turing also lived proof that inner experience is irreducible to external labels. His humility here mirrors his career-long honesty about what computation can and cannot capture.
The era
The late 1940s and early 1950s saw computers emerge as serious intellectual tools while behaviorism dominated psychology, reducing mind to observable inputs and outputs. Norbert Wiener's cybernetics (1948) drew parallels between machines and minds, sparking questions the field couldn't yet answer. Cold War anxiety about human versus machine capability gave these questions political urgency. Philosophy of mind lacked the vocabulary to cleanly separate functional from experiential questions—acknowledging that gap was genuinely unusual for the era.
