In this volume, G. Marian Kinget's classic work, On Being Human, can be read for the first time in light of a second, previously unpublished work, Pleasure And Pain. Taken together, these two works offer a new generation of readers a comprehensive picture of the insights, principles, and goals of humanistic psychology. On Being Human, Kinget's pioneering work, which arose from the original humanistic revolution in psychology, systematically describes the characteristics that make human beings different from all other forms of life. In this work, Kinget explores man in his full nature not solely as a biological organism modified by experience and culture. She presents a person as a symbolic entity capable of pondering his existence, and lending it meaning and direction. Man is the only animal who knowingly exists in space and time, manifesting transcendental and metaphysical concern throughout history and culture. On Being Human presents the fundamentals of any valid approach to psychology as well as to other fields concerned with the individuality of the human being. It describes the specific human capacities for reflective thought and declarative language, and it discusses the unique ability of humans to devise culture and question origins. Pleasure and Pain considers the interdependence of human pleasure and pain. This idea, which leads to unnecessary fears and unwarranted expectations, goes unrecognized in a contemporary western society focused on the accumulation of pleasure without any awareness of the duality of the pleasure-pain experience. Kinget refutes the widespread fallacy that fun lies in the means, when it actually lies in the subject, and she discusses the human potential for autonomous "management" of the pleasure-pain dimension of human existence.
