Please help me understand the 5 ways from Aquinas, the first 2 are pretty ''easy'' to grasp, but i am having a problem with number 3 and 4.

1. Argument from Motion – POTENTIALITY AND ACTUALITY.
- Some things are in motion.

- Nothing can move/change itself – the motion of one thing (A) is dependent on an ‘’outside’’ mover (B) – in philosophical terms, the potential to be ‘’moved/changed’’ is actualized by another - B changes A.

- But the thing ‘’B’’ that is moving/changing the first thing ‘’A’’, must itself be moved/changed by another thing ‘’C’’ – C changes B, which changes A.

- The series repeats itself until we get to what Aristotle called the ‘’Unmoved mover’’ a.k.a. something that doesn’t move and has no potentiality and what Aquinas called ‘’Actus Purus’’ - PURE ACTUALITY.

- The chain of causes is ordered ESSENTIALLY – which means every member of the chain is dependent on the previous member at this very moment.

EXAMPLE:
Stone <(moved by) < stick <(moved by) < hand <(moved by) < Muscles <(moved by) < Neutrons in brain <(moved by) < ‘’Fundamental’’ forces <(moved by) < ...???... <(moved by) < ‘’Unmoved mover’’.

Would this be a satisfactory representation of the 5 ways from Thomas Aquinas?
