An idea of connections

An idea of connections is an idea of things connected. History, for example, is nothing if not connected. It is littered by people trying to perceive connections between events, for surely, events are connected. All things are relationally connected, since the world is one relational whole. Thus it may be said all things are relatively connected — although some people have difficulty figuring some connections, such as between a blue-ball pen and a frog. Most connections though are not situationally relevant, nor even worth much. Detectives are theoretically better at imagining connections between entities than are generic peoples—hence the name detect-ive, as in detecting connections. Discoverers or inventors do this too—all three classes are types of investigators who work with the idea of connections—but so do IT people. An IoT might walk into a cabin and start seeing how the things in the cabin might connect cybernetically, while the detective might look for what kind of person has been living there.
The Internet is based on an idea of connections—especially designed to survive a Nuclear Weapon Attack on the United States Government Infrastructure. Now that is moving further into our environment, in what is called an Internet of Things (as if the Internet hasn't always been an internet of things).
The Fourth Industrial Revolution is heavily based off the idea of connections. P2P networking is an idea of connections.
We refer to a state of connection as nexity. Things with high nexity are highly-connected.
