The technicalities are the entire point!

If the fundamental nature of reality can't be analyzed technically, what can be?

The evidence that things are non-physical is quantum physics experiments showing that the fundamental components of existence lack the properties of physical things.

The two slit experiment shows that photons behave in non-physical ways.

The indeterministic wave function shows that reality does not depend on strict physical laws but on randomness, and randomness is not mechanisitic. Materialism is based on mechanics but quantum strangeness violates mechanics, therefore mechanics is empirically wrong.

The Schrodinger's cat situation shows that reality is dependent on observers--but matter is said to exist without regard to observers at all. The physical moon still exists when you aren't looking at it. The Schrodinger's moon does not--just as Berkeley claimed in 1713.

Bosons show that two objects can take up the same space at the same time.... but physical things cannot occupy the same space at the same time. This is like saying that you can drive a bulldozer into a house but the bulldozer and house don't have to destroy each other, that they have the option of happily occupying the same space. The materialism hypothesis would say this is impossible. "Physical" things do not behave like bosons, therefore bosons aren't physical things.

The evidence that the materialism hypothesis is wrong is quantum physics, where things don't behave in the ways that the materialism hypothesis claims they should. Therefore the materialism hypothesis has been falsified and refuted and is wrong.

Entire quantum physics is a mathematical model of physical things by definition. Quantum wave function is a physical object as are all the other fundamental fields we know about. Photons behave in very physical ways, just not in classical ways like you would expect them based on experience with macroscopic objects we face every day. Likewise, bosons are physical objects that have physical and measurable/observable properties (but they don't have volume) etc.

So now you are getting a bit confused here.

Quantum physics doesn't follow from definition, it follows from experiment. You are confusing a priori statements with a posteriori statements.

>Photons behave in very physical ways, just not in classical ways

What are "physical ways"? What are the properties of "physical ways"? When confronted with a hypothetical 'way', how can we know if that 'way' is physical or non-physical?

The answer is that physicists assume that all existents are physical and then conclude, based on that assumption, that materialism is correct. This is circular logic because materialism is simply the doctrine that everything is physical. So all they have done is assume that materialism is correct and then conclude that, because materialism is correct, materialism is correct.

In order to argue that materialism is correct you first have to define what materialism is, and what it is not. Is the materialism hypothesis even falsifiable? Or is it the kind of hypothesis that changes as soon as it is refuted?

Actually quantum mechanics can be formalized and derived entirely from a few simple and reasonable axioms (that allow for negative probabilities), but yes historically quantum mechanics has been developed through empirical experiments. After all physics is (empirical) science unlike mathematics.

What I meant to convey was that all elements of the theory like quantum wave function, elementary particles (bosons, fermions etc), are elements of that physical model and hence real in that model by definition. It kind of makes no sense to talk about model independent reality, as quantum mechanics so nicely demonstrates.

This is why your statement that bosons are not physical is nonsensical.

In any case most real scientists are entirely open to new evidence of what you would call non-physical things (historically these were usually spirits, souls, demons, gods etc), but historically no convincing evidence has ever been provided for these. On the contrary each time mysterious phenomena turned out to be completely physical and explainable within normal physical framework, and in other cases clearly dreamed up.

It really isn't correct to say materialism or science is doctrinal. After it is not required to believe everything has to be material or explainable within our current framework (it would be akin to saying we already know everything).

However, opposite of materialism is dogmatically imposed in a lot of religions. It is a tenet of Catholic Church for example that materialism can not be true since souls and spirits must exist. This is not open for debate you must accept this to be a catholic. Just so we understand distinction between dogmatism and experience that everything we ever encountered so far has turned out to be physical. I will take evidence over dogma any day.
