George F. R. Ellis - What Is Strong Emergence?

Strong emergence is when something new shows up that you can’t really predict just by looking at the parts it’s made from.

Imagine you have a toy box full of simple blocks, red, blue, and yellow. Each one is just a plain block, no special powers or hidden tricks. Now, if you stack them in just the right way, they might suddenly make a tower that wobbles and stands on its own! That tower isn’t something you could see in any single block, it’s a whole new thing.

Like legos making a robot

Think of strong emergence like building a robot with Legos. Each Lego is simple, just a small piece. But when you put them together in a clever way, that robot can walk or even say hello! You couldn’t have guessed the robot was inside those little Legos, it only shows up when they all work together.

A real-life example: ants

Or think of an ant colony. Each ant is just one tiny creature doing its own thing. But together, they build amazing structures, like a whole city! You can’t see the city in any single ant, that’s strong emergence too!

It's like magic, but not magic, it's clever teamwork from simple parts!

Examples

  1. A group of ants working together to carry food is an example of strong emergence, where a new behavior appears that no single ant had.
  2. When you mix red and blue paint to make purple, it's like strong emergence, something new comes from combining parts.
  3. Strong emergence is when simple rules create complex patterns, like how traffic flows on busy roads.
