I didn't understand the significance of AA until I read Infinite Jest. I knew what the acronym meant, and I knew people who had been in it, but for me, it was one of those vaguely defined cultural terms that float around in the air, like "Hedge Funds" or "Corrugated Metal." I understood, but I didn't know. I still don't know, fortunately, but I think I better understand.
AA represents a process of mandatory virtue development. As an addict, you get sober, or go insane, or die. The literature, then, in order to be effective, has to appeal to this mindset. That means it needs to be firm, but gentle, and quick, and, perhaps most importantly, a little eccentric.
Firm in that it does not give equivocal advice. Gentle in that it doesn't beat you over the head with it. Quick, not meaning it is simple, but 'quick' meaning you don't have to keep a reading journal to understand it. And eccentric in that the advice does not necessarily fly in the face of common wisdom or social norms, but also does not go along with mainstream wisdom, either.
This book helped me get over myself. The core thesis is that resentment is a result of us continuously replaying perceived slights in our imagination, not forgiving, not letting go, not moving on. This hurts our pride, and instead of healing, we pick at it. Fr. Pfau had no delusions about "eliminating one's pride." He just offered solid advice and slogans for getting over a little trick of human nature that, if unattended, can tear us apart from the inside.
I would like to read Fr. Pfau's other golden books.
