"But in my life, a brief review revealed, everything was not always wrong, and neither was nor is always wrong in the community in which I live, or in my country. Further, it was not always wrong in previous communities in which I lived, and among the various and mobile classes of which I was at various times a part.
And, I wondered, how could I have spent decades thinking that I thought everything was always wrong at the same time that I thought I thought that people were basically good at heart? Which was it? I began to question what I actually thought and found that I do not think that people are basically good at heart; indeed, that view of human nature has both prompted and informed my writing for the last 40 years. I think that people, in circumstances of stress, can behave like swine, and that this, indeed, is not only a fit subject, but the only subject, of drama."
Dammit, Mamet, you're so good.
