Imagine that two people who have the ability to read anyone's mind confront each other. Each one of them knows that the other is able to read minds and so they try to read each other's mind.
Let's call the two subjects Subject A and Subject B. :
Subject A starts reading Subject B's mind, but simultaneously, Subject B starts reading Subject A's mind. Assuming that the process of thinking is finite, eventually the thoughts of Subject A or Subject B should lead to something concrete, but apparently, both of them would be reading each other's mind in a endless process that would require an infinite time to get it done. So the question is the following:
Would anyoneeither of them be able to think something concrete after a finite amount of time?
