The system becomes more coherent as it is further extended. The elements which we require for explaining a new class of facts are already contained in our system. Different members of the theory run together, and we have thus a constant convergence to unity. In false theories, the contrary is the case.
About this quote
- What does it mean?
- A good theory grows more unified as it expands, integrating new facts without needing new elements; false theories fragment.
- In plain terms
- Strong theories become more cohesive as they explain more, while weak ones fall apart.
- What can you take from it?
- Aim for theories that unify rather than multiply assumptions.
