Fool,
Ok, thanks for clarifying. The part I want to point out is that I agree with the majority of your points, but I'm not convinced they defend relativism. I acknowledge that evidence can be consistent with multiple theories, and therefore one model can be equally justified as another. In fact, I am willing to take this a step further by stating there are an infinite number of theories that are consistent with every unquestioned scientific theory, and only the values of science including parsimony, coherence with related theories, and popularity narrow them to fewer possibilities.
To the contrary, I reckon they defend the falsification interpretation of science. The view lacks the dogmatism of previous scientific philosophy, and instead demands that scientific theories be falsifiable. That is, they can be tested for inconsistency with evidence. Moreover, this interpretation does not imply that other methods of gaining knowledge are incorrect, but that there are practical reasons for favoring the scientific model over others.
Although this view may seem relativistic, it is in fact more consistent with skepticism. According to skepticism, we can not verify if a theory is true or false, but that does not mean it isn't. Rather, the suspension of judgement is concluded. In a sense, the current evolution of the falsification interpretation has resulted in a marriage between skepticism and empiricism. As for relativism, skepticism would assign it a dogmatic status. Although relativism often employs skeptical arguments, it is often missed that skepticism is a double edged sword for relativism.
