It doesnt really make him a genius (though he was one). It just makes him very well read and more educated then most of his peers. But to me, his genius was more in his songwriting ability then how well read he was. His ability to communicate so many different emotions through words was unmatched.
If you listen to one of pac's interviews you'd now he was no longer throwing up the dub as westside an that the "W" now stands for "WAR" also it's his one nation interview i believe talks about bringing the west & east back together in harmony.
