One day the great philosopher Thestikles was sitting in the agora eating some kikiam and olives. He saw a fellow philospher passing by and without warning Thestikles gave him a hard blow on the head.
"Pakshet! Why did you hit me Thestikles?"
"I predicted that you were going to hit me today so I made a preemptive strike"
"I was not going to hit you! Why would I hit you?"
"Well, how can you be sure that you wouldn't hit me? Think of all the times I embarassed you in front of the whole lyceum, the time I tripped you in the Olympics, the day I overheard the oracle tell you that your mother will kill you and marry your brother. Can you honestly tell me that deep within your heart you did not want to cause me harm?"
"I agree, I do hate you. And my hate right now is so great that I will strike you now in righteous retribution!"
"But in doing so you make my prediction true and everyone here will know that I, Thestikles, am indeed a great philosopher!"
"Well, then. I will let this pass and show everyone that I am dignified enought not to stoop to such petty violence. Thus, it will be you who will be seen as the villain."
"Admirable move! I am shamed excessively!"
When the other philosopher was gone Thestikles took out a notebook and made a mark. "That makes twenty-five. I think Im getting the hang of this!"
Thus was political science born.
