Parity and Lawlike Comparability

Parity refers to the idea that physical laws should treat all possible configurations of a system equally, without bias toward one state over another. It implies symmetry—if a law applies to one situation, it should also apply if you mirror that situation. Lawlike comparability, on the other hand, is the principle that one can compare and relate different laws of nature coherently; they should fit together in a way that makes sense across various contexts. Together, these concepts suggest that the universe operates uniformly and predictably, regardless of how we observe it.
