This book offers a set of reflections that the health field must absorb to influence behaviors that promote autonomy and dignity. It is dismaying the removal of the old conceptions about the health-disease processes, the cognitive blindness regarding the inexorable generization of such phenomena and, very especially, the recusal of contextual perception to make intelligible the language of the body that enunciates its meanings contrary to natural budgets. I have often held a warning, and it seems more than adequate to welcome this book back to it: for those who absolutely believe that there is a transparent reading of the phenomena of nature. Its language is the one we have invented, an arbitrary mediating option with which we take principles and laws for granted. It is convenient to abdicate its arrogance, and to make health a libertarian statute, as it emerges as a spur from the pages of this text.
