Infanticide is one of the most common, yet least understood of all human crimes. Although academic articles document isolated aspects of this problem, a single, unified analysis of infanticide has not been completed until now. In Hardness of Heart/Hardness of Life, Larry Milner provides the first exhaustive survey of infanticide, drawing on historical data from around the world. He then uses this survey as a basis for investigating why infanticide has been present in every form of human society throughout history. Both comprehensive and compelling, this important study will intrigue students of human psychology, social welfare, and child abuse, and will promote further research on this alarmingly overlooked atrocity.
