DISCUSSION: Dr. Alexander Bromley commented that the authors emphasized only one factor, filicide, in human history, and disputed the thesis that filicide is universally denied and neglected. He summarized the basic theories of Melanie Klein in order to place the Rascovskys' thesis in perspective, noting that in Kleinian theory the Oedipus complex is regarded as a defense against anxieties arising from the paranoid-schizoid and depressive positions. Dr. Charles Brenner challenged the authors' supposition that a child at birth, or in the first few weeks of life, can comprehend that his parents tried to kill him. After citing three categories of instances of infanticide, Dr. Stuart Asch postulated that most infanticide is between the mother and the newborn, male or female.
