This book provides an overview of the basic concepts of a systems theoretical perspective using families and family therapy as examples and illustrations of their application in professional practice. This meta-perspective focuses on viewing problems in context. The difference between first-order and second-order cybernetics is explicated. Readers then are invited to see themselves as parts of the systems with which they are working consistent with a second-order cybernetics perspective. Along the way a difference between modernism and post-modernism as well as constructionism and social constructionism also are described. In addition, theories of individual and family development are presented with implications for their use in family therapy. The book concludes with more than 100 examples of how the meta-perspective of systems theory can be used in work with families.
