The human race now declared that i t rules the world. We ＂ officially＂ declared the start of a new era in the history of the Earth, the Anthropocene. The Ex-ecutive Committee of the International Union of Geo-logical Sciences accepted the proposal that humanity＇s impact is so large that it merits to call an era after it-self, although there is remaining disagreement of its precise start （ Head et al. ,2015） . Some argue that this is a mark of accepting responsibi lity - I remain of the opinion that this is hubris, both ridiculous and danger-ous. Ridiculous, because it is simi lar to many fields, where declaration of new and new eras, paradigms, etc. appear at increasing frequency as we approach the present. Earth-shaking discoveries and truths are daily announced. Do they really happen so frequently？ Hardly. And the gods are laughing.
