From a random discussion on Facebook comes a rather interesting comment:
I’m not arguing against science or the scientific method at all. In fact, I wasn’t even espousing a particular worldview or religious dogma. My point was simply that Scientism as a worldview is incoherent. This is because Scientism maintains that the ONLY knowledge which is valid comes from the scientific method. But how do they arrive at that conclusion? Using the scientific method? The scientific method cannot be its own justification. Proponents of Scientism are making a metaphysical and epistemological declaration which cannot be arrived at empirically. That was my only point. The same problem holds for Logical Positivism which states that the only meaningful statements are those which are scientific in nature. But that is not itself a scientific statement, but one of abstract reason.
