Clausius¿s second law analysis is a peculiar construction indeed, as in it the criterion that allows for the discrimination between reversible and irreversible processes -the entropy function- is concocted from the precise opposite notion; this is, from the assumed identity in nature between the reversible and irreversible transfers of heat. The corrected analysis not only challenges the alleged universality of the law of increasing entropy; it also allows for a re-conceptualization of Thomson¿s problem about the impossibility of restoration of mechanical energy, as well as hints a new paradigm for the study of self-organizing phenomena.
