As I have walked thru the argument from cause, i.e., every effect has a cause apart from itself, my interlocutor brings up the fundamental forces (gravity, electromagnetic, strong & weak). He argues that, at least, 2 of those forces are "internal" to the atom and not something apart from it; perhaps even all 4 forces are internal to the tiniest particle of matter. If true, and I haven't conceded that yet, does that change anything in the cause-and-effect argument or in the argument from motion -- that we have an effect coming from a cause within? Or do we ask "what caused the 4 forces"?
