“If we are going to help make a healthy world it is essential that men become kind and soft and step down from the altar of power. These things were not spoken in medical school maybe because most all the teachers were male, and psychiatry did not address the unhealthy features of the male personality. Thank you, Peter, for showing the possibility for a healthier world, making healthier men.”
