Unscientific vs. ascientific

Meta-science

Sometimes "science" is used as a word of good positive valence, and then when a thing is not scientific that means it's Bad and should be Purged in Holy Fire. But take care to only do this on unscientific things, like baseless hypotheses. By contrast, ascientific things are okay: things to which you cannot apply science even in principle.

For example, history is Awesome and Smells Good (it should not be purged in holy fire), yet history is not a science.
