Why Do We Prefer One Theory Over Another?

Observational evidence can constitute a genuine reason for preferring one theory to another. The reliability of scientific reasoning is not just an attribute of us, it is also a new fact about physical reality itself. Galileo expressed in the phrase, the book of nature is written in mathematical symbols. It is impossible literally to read any shred of ethereal nature, that is the inductivist mistake. But what is genuinely out there is evidence, or more precisely a reality that will respond with evidence if we interact appropriately with it.
