This article explores an interaction between posthumanist and cognitive discourses through the work of award winning Mexican author, Guadalupe Nettel. I focus on her 2014 anthology, Natural Histories, rereading the central motif of the narrative, that animals ‘are like a mirror that reflects submerged emotions or behaviours that we don’t dare to see’ (Nettel, 9). This ‘reflection’ is not simply the image of the human reflected off the opaque surface of the animal, but rather the humans themselves act as a mirror, simulating the behaviour of the animals with which they cohabit. This can be read as a literary representation of a neurophysiological phenomenon — embodied simulation, an internal mimicry, either perceptible or imperceptible, performed when watching others completing certain tasks, movements or expressions (Gazzola et al. 2007; Uithol et al. 2011; Iacoboni 2009). In particular, the first story, ‘El matrimonio de los peces rojos’, depicts a profound human-nonhuman embodied resonance that moves between linguistic, narratological and characterological levels. A cognitive critical approach to the mirroring between animals and humans in the stories reveals the particular intersection between new paradigms in cognitive science, animal studies, and posthumanism that the anthology develops, each of its narratives intertwining mind, body and nonhuman other in a non-hierarchical network.
