The Outlook of the Tekhne Iatrike and the Medical Act to the Third Millenium

Medicine is arriving at a new millenium. One of its most urgent tasks is to reconcile social health demands with a renewed medical paradigm capable of including them. This challenge requires a reexamination of the definition of medicine. This work takes up the original greek definition of medicine (Tekhne Iatrike) and the Medical Act according to P. Lain Entrago, and analyzes Heidegger's interpretation of Tekhne. It points out the two main ways in which current medical practice is sustained: the Instrumental Medical Act (IMA), which organizes medical production, and the Productive Medical Act (PMA), which motivates it. An overwhelmed Medical Act, fighting but incapable of optimizing an insufficient medical production, is observed. This medical act is searching for foundations: an hegemonic IMA, associated disciplines and a new medical hierarchy.
