I don't mean to invoke any arguments that are in discord to science. It's a linguistic issue. I don't think calling certain 'somethings' immaterial should be regarded as nonsensical based off the idea that there are material causes for the things some might regard as immaterial.
If we talk about a chair being material, we don't go off on a tangent about the forces at work, but as soon as the discussion turns to the immaterial, we do. There's going to material causes for both, so the tangent is unnecessary. An object that doesn't have material form isn't an object at all, but not having material form doesn't mean it doesn't exist. Take the force of gravity, for instance. It's not an object. It's immaterial. You can't tell me it's constituent material parts, like you can a chair. You can only list the material parts that make gravity possible.
You can't tell me the constituent material parts of a chair, any more than you can gravity.
QFT tells us that 'particles' are simply local maxima in the values of fields of force. The Higgs field causes these field maxima to propagate at less than
c in free space, so they have mass; and the interactions between these field maxima are energetic, and therefore also have mass (E=mc[su]2[/sup]). The majority of the mass we encounter is of the latter kind, but the interactions that lead to that mass rely on the smaller mass component from the Higgs field; absent the Higgs, all such 'particles' would, like photons, move at
c, and interactions between them would be far less common.
A chair, like gravity, is a manifestation of force. Your point makes sense in a world of classical (Newtonian) physics; but we do not live in such a world.
