What is it precisely, that they are doing when they are doing science. Are they refining their instruments for observation or discovering new aspects of reality?
Paraphrasing Plato's Republic: "Only people who have allowed themselves to be reformed by reality have it in themselves to reform their polis for the better."
Given cognitive vulnerabilities, it would be convenient to have an arrangement whereby reality could tell us off; and that is precisely what science is. Scientific methodology is the arrangement that allows reality to answer us back.
Philosophy is this amazing technique we've devised for getting reality to answer us back when we're getting it wrong. Science itself can't make those arguments. You actually have to rely on philosophy, on philosophy of science.
So dogma, doctrine, unexamined assumptions, that's what it is to be sharing that, the hippies shadow, no way of grounding it to reality. It's where we're just cut off from reality unless we can argue, we can substantiate, we can justify, we can convince each other.
