Here is an image I found very interesting, it helps me understand the classical concept a bit more. As you can see there are four different pictures of what a “tree” is suppose to look like. They have different shapes, but they all contain the same characteristics that make up a tree. All four images have green on the top to represent the “leaves”, and some type of brown at the bottom to represent the “trunk”. The very last drawing at the bottom is the foundation, it states that all the other four images on the top make up a tree, because they revolve around the concept of what a tree consist of.
