I find the inherent contradictions to be amusing.
My word is fascinating (apparently endlessly for me), fascination being a type of amusement, but yes, that's the appeal.
Based on what I have observed, I think scientism was invented by belief-based thinkers as a straw man to beat on for the successes that have resulted from the knowledge acquired through science and the successful application of that knowledge through technology.
The word is a bit like "woke" now. It means nothing when used to describe empiricists (see below).
I don't "accept" the germ theory. Rather I see extensive evidence that many specific diseases have germs at their root.
That's you accepting the theory right there. The theory is that there are diseases that are caused by microscopic living organisms invading and harming other living things. Imagine what it was like to be alive when that news came out - living things that can kill you are invisible and everywhere.
I'm sorry but this appears to be mystical. Scientism.
I've seen that word used two different ways, one derogatory as you are using it here, and one much less commonly, one non-judgmentally descriptive and essentially the same as philosophical naturalism ("empiricism is the only path to knowledge."). One cannot rely on empiricism too much, but one can rely on it too little.
Reality is far too complex to be "explained by science"
My world is not too complex for me to benefit from approaching it empirically.
All "learning" about reality must be based on empirical knowledge as interpreted in terms of theory.
Yes, knowledge follows from observation and successful induction, and only from these. That's what I call knowledge, and the acquisition of such ideas learning.
Are you turning to scientism now? Those advocating for faith as a path to knowledge would call you excessively reliant on empiricism for it.
To some extent even controlled observation can take on characteristics of "experiment".
Experiment is controlled observation assuming that you mean that what is being controlled is what is being observed rather than the means of observing it such as a telescope or a pair of eyeballs.
