I remember reading somewhere (in a few introductory university course text books, I believe) that science is founded on 5 principles, or "pillars", as I'm calling them. I can't remember what they are though. Here's my guess:

 

1) empiricism

2) determinism

3) repeatability

4) testability

5) parsimony

 

Am I missing anything? What about reductionism? What about explainability?

I`de expect that "Explainability" comes as a natural function to "repeatability", as in you can`t hope to repeat what you don`t understand or have knowledge of.

 

just a thought
