I viewed several of his production a few years ago. He had no true insights. His "logic" was like holding a flashlight walking in dark, and could only lead to see from spot to spot. The reason behind this was that he had no genuine values 價值觀, hence had no true vision.
I also viewed his interview by 許知遠. He didn't seem dishonest, yet he did seem having himself misled by his own false intellectuality and the success in turning it into business of profits.
