Epigenetics could be a challenging point of view for biologists and physicians as it allows to consider different levels of explanation and to link them together in a dynamical way. Structured as a discipline more than 50 years ago, epigenetics has been rediscovered only in the last decade after the failure of some genetic hypotheses. Compared to Waddington\\\'s formulation, contemporary epigenetics - in particular when applied to medicine - is often considered in a narrow manner, and when placed in high-throughput analysis in most cases it acquires new meanings. In that \\\'narrow\\\' context the molecular level represents both the departure and the arrival point. I will show some cases from biology and medicine and after some linguistic and historical considerations I will pinpoint some philosophical issues.
