So if we can explain how human self-awareness works it will be a Rosetta Stone to understanding what makes our species so odd, or, depending on your view, so special. Also: big brains love exercise. And the great thing about this topic is that it can be tackled by biologists, neurologists, philosophers, physicists and even novelists. It’s an interdisciplinary, no-holds-barred intellectual wrestling match. Michael Pollan, an American journalist and academic who works at both Harvard and Berkeley, comes
