From the pamphlet A Member's Eye View of Alcoholics Anonymous

There must come a day, it seems to me, when every alcoholic, in or out of A.A., finally sits down in the presence of his enemies. When he does, he will be amazed to discover that he is attending a meeting of one - himself. The day the alcoholic in A.A. realizes that his enemy is within, that the tigers are largely creatures of his own design and lurk in his own unconscious, that is the day when for him A.A. becomes what I believe its founders meant it to be: a flight into reality.
