Did all the early philosophers agree with Plato's Charioteer and the Horses theory.  I searched on the Internet about philosophers and emotions and came across an paper from Stanford University that discusses many different philosophers opinions on emotions over the ages to today.  As I read it, it names several well know philosophers who disagreed with Plato's Charioteer and the horse theory.  One of which was his own student Aristotle, who influenced the philosophical group, the Stoics.  Another famous philosopher that agrees with Plato is Cicero.  As I continued my search I discovered that the debated of emotion and rationality has been waged for a long time as shown in another paper I found.  I will admit that about ninety percent of the stuff in the paper I could not understand, but I was able to understand that they did not agree with Plato.  Another question I have is how long can it take for a man's frontal lobe to fully develop.  For me personally, it seems that my frontal lobe is still far from being fully developed.  I am just probably being paranoid or weird.  So, in order to solve this mystery, I searched on the web about frontal lobe development.  I discovered on a website that in men that their frontal lobe does not full connect until they are in their mid-twenties on average.  Some can take a longer time and others a shorter time.  It also shows on a graph that the connection between the frontal lobe and the brain get stronger and stronger until  a person reaches their forties and fifties.  This answer makes feel better.  It just show me that I am not a fully rational person yet, and I have an excuse.
