There are no core beliefs in AA. There are a lot of truisms and maxims that you hear over and over again - "stinking thinking," "one day at a time," "alchoholism is an equal-opportunity illness," "don't get too hungry, angry, lonely or tired," etc. etc., but they are not "core beliefs." Even the 12 steps are not beliefs, but decisions or actions that one takes on the road to recovery. AA also has 12 traditions that are principles by which the AA organization conducts itself.
