I have a problem to which I haven't been able to find a solution for hours. Recently, I have been reading Pygmalion by George Bernard Shaw, and there is a sequel after the story ends. In that sequel, Shaw wrote such a sentence,
"To her amazement she found that some "quite nice" people were saturated with Wells, and that this accessibility to ideas was the secret of their niceness."
I can't understand what "be saturated with" and "accesibilty to ideas" mean. I have done some search on these 2 on Google but haven't been able find any satisfying answer. Please clarify me; I'd be so much grateful for you. Thanks.
