Sobre la necesidad epistemológica de la investigación cualitativa en salud

Western society has accepted the mathematical concept of number uncritically almost from the Pythagorean School. Georg Cantor's work on the concept of infinity and on set theory and Kurt Godel´s logic investigations on incompleteness has shaken clarity of numeracy. These inquiries together with methodological discussions between frecuentists and Bayesian statisticians and applications requirements of evidence-based medicine make necessary the contribution of qualitative research for the analysis of reality of health. It is also desirable epistemological definition within each qualitative project.
