Scientology Axiom 6

Axiom 6: Objects consist of grouped particles.

I don't think you'd argue about that. It is very obvious that, for example, the monitor you are looking at consists of grouped particles. It clearly has sections and different pieces but breaking it down further there are molecules and those are made up of atoms, and those are made up of protons, electrons and neutrons and those are made up of quarks and other sub-atomic particles and those are made up of ... etc., etc. So where does it all end? A particle could be described as a localized motion. The physical universe is made up of motion and really nothing else. You can go on finding motion within a physical universe object forever, but if you were to stop the motion you'd end up with nothing.

Whether it is valuable to keep on breaking particles down and down and down is a debatable point, but the axiom above isn't really debatable because it has been proven true so many times and in so many different fields.
