All science is materialistic

[Angrboda]

I have used the word "materialistic" in the following sense:

By this definition, scientific materialism is linked to the more general version of materialism, which declares that the physical world is the only thing that exists and that nothing supernatural exists

To anyone who will actually take the time to read what I have written, such will be clear.  For instance, I never referred to photons as being a form of "matter".

I think you've linked to the wrong article.
