Book Recommendations on the Ego?

He was concise and articulate, I enjoyed listening to him, but I just found it ironic that in talking about creating something new, there were no ideas offered about what 'new' should encompass. I certainly wasn't looking to him for answers, but I was hoping that a dialogue would form between him and the audience, yet nothing new was discussed. Kind of defeats the purpose of talking about shaping tomorrow if we don't discuss what tomorrow should be and how we get there. My critique is that he needs to be more engaging with the issues.

I'm reading the preview of No Boundary by Wilber and it doesn't sound too bad for a beginner.
