“ We are, each of us, largely responsible for what gets put into our brains, for what, as adults, we wind up caring for and knowing about. No longer at the mercy of the reptile brain, we can change ourselves.
Most of the world’s great cities have grown haphazardly, little by little, in response to the needs of the moment; very rarely is a city planned for the remote future. ”
