Contributing to contemporary debates in phenomenological psychopathology and enactive psychiatry, this book argues that a comprehensive account of mental illness and its treatment requires engagement with subjectivity. It advances an enactive model of the mind that articulates the dynamics of lived experience and provides an integrative framework for psychiatric research and clinical practice. Recentering subjectivity, the book outlines a more unified and productive direction for the field aimed at psychiatrists, neuroscientists, and other mental health professionals Organized into two parts, Part I examines psychiatry's historical movement toward objectivity and the consequences of this shift, offering the conceptual resources needed to critically address-and move beyond-the concerns that motivated it. Part II develops a positive vision for an enactive psychiatry structured around the Nested States Model (NSM), demonstrating how the NSM can help guide both clinical practice and research towards a more comprehensive understanding of psychiatric disorders.
