Sorry about the broad question. I'm still learning to frame the questions on Physics StackExchange. Currently researching the nature of interactions in philosophy.
My question is: When physicists use the term "fundamental", what do they mean?
In philosophy, most seem to claim that to be fundamental means to be the source of causal power. That is, to say that quarks are fundamental means that if we can find exactly how quarks interact, we can explain all phenomena in the world because everything is made up of quarks after all (the behavior of quarks is the primal cause for all phenomena). And philosophers also tend to handpick findings of physical sciences to support this claim.
I sense that this might be an incorrect picture and want to understand what fundamental means in physics to be able to clearly write why we might be using a mistaken notion of fundamental.
