ere the rock is X, the earth is Y and the sun is Z.Another point I would like to bring up is The Law of Conservation of Energy which states “Energy can not be created nor destroyed. It is only changed from one form to another.” What does it mean to the argument and us? It means that at one point all the energy was created at once and it changes its form by moving and being moved. The energy travels from X to Y to Z to…N, while X moves Y, Y moves Z and Z moves … N. Going back to infinite series of movers, which is impossible, we can argue about existence of a first mover which is moved by nothing else and this “everyone understand to be God” “The second way is based on the notion of efficient causation.” The second way has Aristotelian background. Aristotle proposed four types of explanations (causes). Material cause, like bronze of a statue. Formal cause, like definition of a man as “two legged land animal”. Third is the origin of a change, like father who begets a child. The Final cause, like the end or a goal, that for the sake of which something is done. Aquinas uses third type of Aristotelian explanation when he speaks of efficient cause in the second way. It might seem that second way overlaps with first way, but it is not true. The first way looks at the problem from the point of view of body acted upon, while the second way considers process from the other end, from the mover’s side rather then thing in motion.By the second way, Aquinas means that we that certain efficient causes cannot exercise their casual activity unless they are also caused by something else. But nothing can be the efficient cause of itself. One cannot regress to infinity in ordered efficient causes. In ordered efficient causes, the first is the cause of the intermediary, and intermediary is the cause of last, whether the intermediary is one or many. Hence if there were no firs...
