This work is a review of the philosophical analisys surrounding the co
ncept of ''humanism'' and what it means to be a human being, in relati
onship to daily life, education and medicine. The authors establish a
direct relationship between humanism and bioethics as they relate to t
he new trends acquired through the development of institutional medici
ne and the increasing application of technological innovations in the
health field. Both of these conditions tend to depersonalize the pract
ice of medicine, and transform an ill person into a clinical file. Ref
lections are made about current topics, such as the knowledge and mani
pulation of human genoma, assisted reproduction, abortion, survival of
premature infants, organ transplants, technological innovation, eutha
nasia and disthanasia. Concepts and ideas are reviewed in relation to
medical institutions and the sick, the physician and the community, an
d the physician and the government.
