.. For a piece of famous fluffiness that doesn't just pretend about what real lives can be like, but moves on into one of the world's least convincing pretences about what people themselves are like, consider the teased and coiffed nylon monument that is 'Imagine': surely the My Little Pony of philosophical statements. John and Yoko all in white, John at the white piano, John drifting through the white rooms of a white mansion, and all the while the sweet drivel flowing. Imagine there's no heaven. Imagine there's no hell. Imagine all the people, living life in - hello? Excuse me? Take religion out of the picture, and everybody spontaneously starts living life in peace? I don't know about you, but in my experience peace is not the default state of human beings, any more than having an apartment the size of Joey and Chandler's is. Peace is not the state of being we return to, like water running downhill, whenever there's nothing external to perturb us. Peace between people is an achievement, a state of affairs we put together effortfully in the face of competing interests, and primate dominance dynamics, and our evolved tendency to cease our sympathies at the boundaries of our tribe.
