Jean Watson’s first edition of Nursing, now considered a classic, introduced the science of human caring and quickly became one of the most widely used and respected sources of conceptual models for nursing. This completely new edition offers a contemporary update and the most current perspectives on the evolution of the original philosophy and science of caring from the field’s founding scholar. A core concept for nurses and the professional and non-professional people they interact with, "care" is one of the field’s least understood terms, enshrouded in conflicting expectations and meanings. Although its usages vary among cultures, caring is universal and timeless at the human level, transcending societies, religions, belief systems, and geographic boundaries, moving from Self to Other to community and beyond, affecting all of life. This new edition reflects on the universal effects of caring and connects caring with love as the primordial moral basis both for the philosophy and science of caring practices and for healing itself. It introduces Caritas Processes and provides other energetic and reflective models to assist students and practitioners in cultivating a new level of Caritas Nursing in their work and world.
