I wonder if people know that they believe models before they believe their own sight, touch, sense of smell, hearing, taste, or thoughts. Every theory that is held by modern physics, for this is the foundation of science, is a model. Everything that someone says about the world is wholly in reference to this model. The model firstly is believed to be true and more real. Next, what ever is said about the world is tested against this model to help explain the phenomena. The model is more real and more true than the world.
This began ages ago. It is practical. The Almagest by Ptolemy, the theory by Copernicus, Galileo's works, Works by Rene Descartes, The Principia by Sir Isaac Newton, Albert Einstein's Theory of Relativity, Plank's works on Quantum Theory, and any work on String Theory are works describing models.
If you want to do something with your knowledge, if you want to make something with your knowledge, if you want technology, then this way of model making is good. If on the other hand you wish to understand the world, the way things truly are, you need to remove this intermediate thwart from your-coming-to-know. For all you understand by the model-making is the model. It is like saying I understand women by the model of them given to me in magazines. All I am doing is testing women in the world against this model in the magazine. I am hardly knowing a woman. Likewise with the world.
