The Anthropocene crisis is inextricably connected to the consumerism crisis of late capitalism, which prioritizes overconsumption of new goods and marginalizes aging objects that were stripped of their glamor in the signal economy. The article examines the axis between collecting and hoarding – daily practices that ascribe to objects value that undermines their routine positions in the consumer culture. The discussion of the new materialisms, a field of knowledge that seeks to redefine the relationship between humans and matter, portrays collecting – and moreover, hoarding – as a space where the distinction between the human and the nonhuman is suspended, destabilized and sometimes even collapses. Beyond the discussion of the psychology of hoarding, a phenomenon previously discussed by philosophers of the new materialisms, this article will focus specifically on the object of hoarding: the pileup. Pileup imposes on us a concept that does not insist on a defined and isolated object that carries an autonomous identity, but proposes a systemic view of human and nonhuman relationships working together without our being able to separate them. Thus the pileup, a materialism that no longer appears in its hierarchical submission to human order and logic, contains the potential for a non-anthropocentric gaze at material.
