Because today we live in a society in which spurious realities are manufactured by the media, by governments, by big corporations, by religious groups, political groups…So I ask, in my writing, What is real? Because unceasingly we are bombarded with pseudo-realities manufactured by very sophisticated people using very sophisticated electronic mechanisms. I do not distrust their motives; I distrust their power. They have a lot of it. And it is an astonishing power: that of creating whole universes, universes of the mind. I ought to know. I do the same thing.

Each of us assumes everyone else knows what HE is doing. They all assume we know what WE are doing. We don’t…Nothing is going on and nobody knows what it is. Nobody is concealing anything except the fact that he does not understand anything anymore and wishes he could go home.
