It is the mind-bogglingly interconnected nature of such networks that inspires the book’s title, Entangled Life , with its deliberate hint of mystery drawn from the idea of entanglement in quantum physics, where two fundamental particles can share a deep connection even when very far apart. It’s tempting, as Sheldrake points out, to see fungi as the biological model for a better world, where everything is enmeshed in a dance of mutual aid.
