During the past few decades, modern technology, with radio, TV, air travel, and satellites, has woven a network of communication which puts each part of the world in to almost instant contact with all the other parts.
Similarly, thought is a system. That system not only includes thought and feelings, but it includes the state of the body it includes the whole of society - as thought is passing back and forth between people in a process by which thought evolved from ancient times.
So one begins to wonder what is going to happen to the human race. Technology keeps on advancing with greater and greater power, either for good or for destruction.
The ability to perceive or think differently is more important than the knowledge gained.
Then there is the further question of what is the relationship of thinking to reality. As careful attention shows, thought itself is in an actual process of movement.
Yet it looks as if the thing we use to solve our problems with is the source of our problems. It's like going to the doctor and having him make you ill. In fact, in 20% of medical cases we do apparently have that going on. But in the case of thought, its far over 20%.
Yet, in spite of this world-wide system of linkages, there is, at this very moment, a general feeling that communication is breaking down everywhere, on an unparalleled scale.
