There’s a psychological school, theory, or effect (depending on who you talk to) known as Gestalt psychology. Gestalt is a German term meaning “essence or shape of an entity’s complete form.” Pretty heavy stuff.
The basic Gestalt effect is best summarized by the idea that the whole is greater than the sum of its parts. There are a lot of different pictures and optical illusions that demonstrate the Gestalt effect. But here’s a relatively good one:
Instead of just seeing three Pacmen and three acute angles when looking at this picture, most people see a white triangle overlapping a black-outlined triangle and three black circles. That’s good ol’ Gestalt working hard.
The Gestalt effect, as a concept that was talked about, originated in the late 19th century. Until then, most people thought that if you studied a thing’s parts, you were studying that thing.
To the modern mind, ingrained with Gestaltian thinking, the idea that people didn’t consider the Gestalt effect seems absurd. I was pondering this absurdity when I remembered the words of Jesus in Matthew 18:20:
For where two or three come together in my name, there I am with them.
And there it is. The truth of the Gestalt effect right there in the Bible. One person plus one person does not equal two people. It equals two people and God and a dynamic relationship.
