Augustus Y. Napier said this quote

Families come into therapy with their own structure, and tone, and rules. Their organization, their pattern, has been established over years of living, and it is extremely meaningful and very painful for them. They would not be in therapy if they were happy with it. But however faulty, the family counts on the familiarity and predictability of their world. If they are going to turn loose this painful predictability and attempt to reorganize themselves, they need firm external support. The family crucible must has a shape, a form, a discipline of sorts, and the therapist has to provide it. The family has to know whether we can provide it, and so they test us.

~ Augustus Y. Napier

The individual psychotherapy patient comes to the therapist with an almost automatic deference, a sense of dependence and compliance. The role pattern is old and established: the dependent child seeking guidance from a parent figure. There is no such traditional image for the family, no established pattern in which an entire family submits to the guidance of an individual. And the family structure is simply too powerful and too crucial for the members to go trustingly into an experience that threatens to change the entire matrix of their relationships. If the family therapist is to acquire that initial authority figure or parent role that is so necessary if therapy is to be more powerful than an ordinary social experience, he has to earn it.

Even though we were still waiting for Don, therapy was well begun. We were engaged in a subtle, often predictable, and very important contest with the family about who was going to be present at the meetings. Carl and I had revealed some of what our relationship had to offer: a good-humored liking for each other, an ability to cooperate, and an insistence on remaining ourselves. I was clearly not going to be the reverential assistant to the older man. And perhaps most important, Carl had intuitively modeled some of the process of therapy for the family. By sharing insight into his own personality, he was saying by demonstration, It's important to search for you own unconscious agenda.

When Carl asked the Brices to bring their whole family to therapy, everyone in the family knew intuitively what that meant. Their whole world would be exposed: all its caring, its history, its anger, its anxiety. All in one place at once time, subject to the scrutiny and invasion of a stranger. And that was too much vulnerability. With its own unconscious wisdom, the family elected Don to stay home and test the therapists. Did we really mean everybody? Would we weaken and capitulate if they didn't bring Don?They had something to gain by the strategy. If we were hesitant and unconfident in our approach to their defiance, they would know that they could not trust us with the boiling cauldron of feeling which their family contained. If we were decisive and firm, they would guess that maybe we could handle the stresses which they intuitively knew had to be brought out into the open. One way or another, they had to find out how much power we had. In the meantime, they postponed facing that mysterious electricity, that critical mass, the whole family. Perhaps they thought they could be spared what Zorba called the full catastrophe.
