Human suicides have occurred and continue to occur at all times and in all societies. Is suicide a viable way to end one's life? What does a person experience during a suicidal crisis? What impact does suicidality have on others? Is suicide prevention a social obligation, and if so, to what extent? The aim of this book is to clarify the position and function of suicide in contemporary social life, to free it from irrationalities, and to understand it as an ethical challenge to all of humanity. It is directed at all individuals interested in the topic of suicide, particularly psychiatrists, clinical psychologists, psychotherapists, social workers, as well as students of medicine and psychology.
