In 1979, Francis Crick, famous for his work on DNA, wrote an essay about the state of brain science, titled “Thinking About the Brain.” He described the large quantity of facts that scientists had collected about the brain, yet, he concluded, “in spite of the steady accumulation of detailed knowledge, how the human brain works is still profoundly mysterious.” He went on to say, “What is conspicuously lacking is a broad framework of ideas in which to interpret these results.”
