I was confused about a few things after watching the video. I did agree with the initial idea, that Government, as an idea, did not exist. What we call government is the interaction of the "authorities" with the rest of the people in that state.Government can not exist if people do not believe in it. The interactions of government would cease if nobody agreed.
But then, I got confused when the example of the family and the forest came up. A person exists, and the parents of that person exists, and that is called a family. But Stephan says that a family only exists in our minds as an aggregation of people. This is where I got confused. The relationship between the parents and child exists whether they are present or not. The relationship being that their DNA recombined to form a new life. A family exists outside of the mind. It is an aggregation of people with a certain relationship.
Then, the forest example. A tree exists, whether you think the tree exists or not. But, a forest, which is an aggregation of trees is only an imagination of an aggregation of trees. But, isn't a tree only an aggregation of cells, and the cell an aggregation of molecules, and the molecule an aggregation of atoms, and the atom an aggregation of quarks? So, all of these things, which exist in our imaginations, do have a representation in reality. A forest exists in reality the same way that deserts and fields exist.
So, can somebody clarify my misunderstanding, or disagreement, with that video.
