There is nothing more mysterious than a TV set left on in an empty room. It is even stranger than a man talking to himself or a woman standing dreaming at her stove. It is as if another planet is communicating with you.Jean Baudrillard
The actual organization of behavior goes on the level of the individual nerve cells and their connections, and we have a hundred billion nerve cells, probably a hundred trillion connections. It's just mind-boggling to think of all the different ways in which they're arranged in a baby's head.Steven Pinker

I try to jog in every city I visit, and I particularly enjoy harbour-front paths that let me ogle big ships, railroad bridges and the ruins of factories and warehouses.Steven Pinker
America is a poem in our eyes; its ample geography dazzles the imagination, and it will not wait long for metres.Ralph Waldo Emerson
