Why does Dr Nemur develop an “inferiority complex” around Charlie?

Dr. Nemur becomes uncomfortable around Charlie because Charlie has surpassed him in intelligence.

Dr. Nemur appears to be uncomfortable around me. Sometimes when I try to talk to him, he just looks at me strangely and turns away. I was angry at first when Dr. Strauss told me I was giving Dr. Nemur an inferiority complex. I thought he was mocking me and I'm oversensitive at being made fun of. How was I to know that a highly respected psychoexperimen- talist like Nemur was unacquainted with Hindustani and Chinese? It's absurd when you consider the work that is being done in India and China today in the very field of his study. I asked Dr. Strauss how Nemur could refute Rahajamati's attack on his method and results if Nemur couldn't even read them in the first place. That strange look on Dr. Strauss' face can mean only one of two things. Either he doesn't want to tell Nemur what they're saying in India, or else--and this worries me--Dr. Strauss doesn't know either. I must be careful to speak and write clearly and simply so that people won't laugh.
