Acknowledgements
We would very much like to thank our son, Alberto Rocha Barros of the Institute of Psychiatry of São Paulo (IPq-HC/FMUSP) and affiliate member of the São Paulo Society of Psychoanalysis (SBPSP), for carefully editing this text while I (Elias) was undergoing corrective back surgery. It would have been impossible for me to complete this text were it not for his enormous help and support.
