I'm going to differ from what everyone else is saying. You should never accept something you don't want in your game. You should allow him to argue for it, and you might want to give him a prohibationary period. However ultimatly the game is yours to run. As such you should disallow anything you think is too powerful or ruins flavor. If the Cerebromancer is more powerful than the rest of the party don't allow it. Being made by wizards does not garuntee it is balanced for every game. I've played in games where parts of the PHB were not allowed, and it was the right decision.
