In First Principles, Alessandra Lemma examines the centrality of applied ethics to psychoanalytic practice, The book focuses on the articulation of an accessible framework for developing and exercising an identifiable method - an ethical self-discipline - to support critical reflection on therapists' psychoanalytic work with patients and to help them to approach the resolution of ethical dilemmas. Integrating key concepts from the field of applied ethics, and bioethics specifically, Lemma re-interprets them for use within a psychoanalytic framework, articulating how we can understand psychoanalytically the concepts of beneficence, non-maleficence, autonomy, justice, and veracity and deploy these to guide clinical work. Using clinical examples, the book outlines a working model for how therapists can reflect on their practice, as well as devoting a chapter on how to teach ethics within psychoanalytic psychotherapy trainings and outlining a detailed curriculum for teaching ethics. This book is essential reading for psychoanalytic practitioners as well as clinical psychologists, psychiatrists, psychotherapists, counsellors, and psychoanalysts who work in the psychoanalytic tradition.
