This book invites individual therapists to think systemically (including issues of social justice) and family therapists to explore a deeper understanding of the individual in contexts, including the domain of the unconscious. Using a critical realist framework, it promotes multiple perspectives - often novel combinations from dissimilar psychotherapy traditions - to expand holistic understanding and provide a richer variety of resources to bring to co-constructed therapeutic encounters. It uses a critical examination of the often-unspoken philosophical underpinnings of psychotherapy practices to re-vision a range of theory and practice considerations - theory choice, the role of science, knowing and not-knowing, emotion in the system, power and autonomy, collaboration and change, and sameness and otherness. All the preceding elements of the book are then brought together in the clinical topics of triangulation, aggressive out-of-control behaviour, and self-harm. Numerous brief case vignettes and longer case examples ensure that theory is always grounded in practice.
