Since then, science has been re-defined -- specifically to exclude anything immaterial. Now, contra Newton, you are free to expell anyone who comes along "claiming to be doing science, while at the same time violating all of the rules of science" as you have freshly defined them.
How conveneient for you.
I can't find a God constant or variable in Newton's laws of motion. “He said, ‘Gravity explains the motions of the planets, but it cannot explain who set the planets in motion. God governs all things and knows all that is or can be done.’” (http://en.wikipedia.org/wiki/Isaac_Newton)
Newton distinguishes between what he is able to describe with science and what is beyond his knowledge yet.
“Since then, science has been re-defined — specifically to exclude anything immaterial.”
For the Greeks science and philosophy was one. With Newton modern science starts.
Newton wrote in a supplement to his “Philosophiæ Naturalis Principia Mathematica” - “Hypotheses non fingo” - “I feign no hypotheses”. That excludes anything immaterial or to be more specific anything not material or not energetic.
By the way, what did Dawkins exactly said in the movie about Panspermia? For me Panspermia can be a kind of ID.
