Okay kiddo, so political naturalism is a way of looking at government and politics that suggests that they are just like everything else in nature. This means that government and politics can be studied scientifically just like we study other things in nature, like animals or plants.
Just like different animals have different behaviors and characteristics, different forms of government and political systems have different behaviors and characteristics too. For example, we can study how democracies work and compare them to monarchies or dictatorships.
Political naturalism also suggests that human behavior is influenced by the environment around us. So just like animals adapt to their environment, humans adapt to the political systems they live in. This means that if we want to understand why people behave the way they do politically, we need to look at the environment they're living in.
So, political naturalism is all about understanding politics and government scientifically and seeing them as just another part of nature that we can study and learn from.
