• Without theories, we would be overwhelmed by disconnected facts (and people learn by stories). They are lenses that help to focus.
• Simplification of reality is needed to model complex reality.

• Don’t take theories too definitely. They will be replaced by better fitting models of reality later… That is the way science progresses!
