No matter how many communes anybody invents, the family always creeps back. You can get rid of it if you live in an enclave and keep everybody else o… - Margaret Mead

In 1946, a Macy Foundation interdisciplinary conference was organized to use the model provided by "feedback systems," honorifically referred to in earlier conferences as "teleological mechanisms," and later as "cybernetics," with the expectation that this model would provide a group of sciences with useful mathematical tools and, simultaneously, would serve as a form of cross-disciplinary communication. Out of the deliberations of this group came a whole series of fruitful developments of a very high order. Kurt Lewin (who died in 1947) took away from the first meeting the term "feedback". He suggested ways in which group processes, which he and his students were studying in a highly disciplined, rigorous way, could be improved by a "feedback process," as when, for example, a group was periodically given a report on the success or failure of its particular operations.

There is no necessary connection between warfare and human nature. Human nature is potentially aggressive and destructive and potentially orderly and constructive.

What are the rewards of the tiny, ingrown, biological family opposing its closed circle of affection to a forbidding world of the strong ties between parent and children, ties which an active personal relation from birth until death?... Perhaps these are too heavy prices to pay for a specialization of emotions which might be bought about the other ways, notable through coeducation. And with such a question in our minds its interesting to note that a larger family community, in which there are several adult men and women, seems to ensure the child against the development of the crippling attitudes which have been labelled Oedipus complexes, the Electra complexes, and so on.
