The concept of universal connection. Nothing in the world stands by itself. Every object is a link in an endless chain and is thus connected with all the other links. And this chain of the universe has never been broken; it unites all objects and processes in a single whole and thus has a universal character. We cannot move so much as our little finger without "disturbing" the whole universe. The life of the universe, its history lies in an infinite web of connections.
