The theory of Generative Death Anxiety (GDA) suggests that at the deepest level, human behavior is motivated by the unavoidable need to shield oneself from consciousness of human mortality. Recognition that fear of death and its consequences necessarily colors the affairs of humans clearly runs through the history of religion and philosophy from the most ancient sources to the present. GDA theory is a developing body of research and writing that stands in this line of human thinking about death, giving prominent focus especially to pervasive human mortality anxiety in the range of its symbolic expressions and the behavioral consequences of this anxiety.
