Newton's Third Law and Causes Prior to Effects

Newton's Third Law is often paraphrased that for every action, there is an equal and opposite reaction. A more thorough stating of this law is that if object 1 applies a force on object 2, then this will simultaneously cause object 2 to apply a force of equal magnitude but on the opposite direction back on object 1. Thus, if I push on my desk with my hand, it might be said (and rightly) that I am causing there to be a force exerted from my hand onto the desk, and that this pushing also causes a second force to be exerted from the desk back on my hand.

However, the two forces spring into existence simultaneously, and then begin once I begin to push on the desk. Therefore, a cause does not necessarily precede an effect in time. It is therefore to be concluded that logical priority does not imply temporal priority.
