Two elements are essential in getting to truth:
- Practice what you believe about the world.
- Always adopt and follow what you find truthful.
The first rule will help you to discover errors.
The second one will help you to get rid of errors.
If you honestly measure up things and events to the paradigm that you have about the world, you discover situations where the paradigm does not work. This process is a continuous empirical verification of life against a model that you have built in the head.
Once the errors of the model are discovered, you have to try to adjust or rewrite the model, so that you can remove the erroneous concepts from the governing paradigm. Thus, you can get closer to truth, or learn.
