Define "material fact".

A material fact is a phenomena that can be observed by the senses and there is evidence and emperical evidence for the fact. The method of science is obsevation of a material fact, evidence and emperical evidence of the fact and a explination of the fact that constitutes theory. The method does not observe anything other than a material fact. Without a material fact there can be no scientific theory. Facts are not absolute and a theory is of a higher order than a fact.

I observed flowers blooming. Material fact?

Without an understanding of the concepts "dark matter" and "dark energy" you can't begin to get a grasp of the small fraction of the Universe that's measurable and observable.

So much for materialism ~ it's only a trivial part of knowledge.
