Þóra Pétursdóttir raises the point that archaeology is limited regarding what it can achieve, including the challenges posed by the Anthropocene, by a series of theoretical assumptions. She challenges the ‘traditional’ archaeological ‘key tropes’ in matters of this new epoch, namely the concepts of culture history, deep time/distant pasts, and the nature–culture divide. Instead, she proposes a number of new guiding points to orient archaeological inquiries, framed as part of the object-oriented ontological (OOO) philosophies. In reply, I claim that the use of OOO theories is rather unhelpful for addressing the topic of the Anthropocene, given that they lead to important ethical and political consequences: a fetishization of things, an abandoning of responsibility and an alienation of humans. They are also based on the confusion that analytical distinctions are in some way the ones responsible for the existence of inequalities, ecological destruction, racism or discrimination. Paradoxically, precisely through their annihilation, there is no room left for acknowledging the alterity of the past.
