Understanding this quote
What it means
The mind isn't a simple or mystical thing — it operates on mechanical principles. The deeper science investigates how the brain works, the more intricate those underlying mechanisms appear. Rather than revealing a clean explanation for thought and consciousness, deeper study uncovers layer upon layer of complexity. This is both humbling and motivating: the brain resists easy answers and demands rigorous, systematic investigation rather than philosophical hand-waving or supernatural explanations.
Relevance to Alan Turing
Turing's entire career orbited this question. His 1950 paper 'Computing Machinery and Intelligence' asked whether machines could think, proposing the Turing Test as a benchmark for machine minds. He designed early programmable computers and studied neural networks mathematically. His later work on morphogenesis modeled biological development as computation. Turing believed the brain was, in principle, a machine — and that building artificial intelligence required first understanding what biological intelligence actually does.
The era
The late 1940s and 1950s birthed modern cognitive science. Norbert Wiener's cybernetics (1948) framed brains and machines under one unified theory of control and communication. McCulloch and Pitts had modeled neurons as logic gates in 1943. Computers themselves were brand new, raising urgent questions about machine intelligence. Society wrestled philosophically, religiously, and scientifically with what separated humans from machines — making Turing's unsentimental, mechanical view of the brain genuinely provocative and controversial.
