Disruptions in Grace: Embracing Mutation and Disability in Nature through Art

Gripping tightly onto a walking stick, I slowly and precariously make my way through the forest. Careful not to catch my prosthetic foot on the exposed roots, I’m scanning the ground when I see a disfigured branch, gnarled, with burls and nodules on it. These masses—called “galls”—are a common growth mutation that can be caused by various factors: bacteria, insects, and rapid changes in weather. I grew up on a fruit tree farm, so I’ve seen this before, but a different familiarity, like a kinship, spurred me to take the branch home. I soon became obsessed with the idea of “tree tumors” and the aesthetics of mutation in nature as a beautiful and intriguing expression of disease and disability. They evoked memories of the way seeing my medical scans eased the abject fear of my cancer – even though the scans felt alien and depersonalized from me, they offered a concrete visual anchor that demystified my diagnosis.

Thinking with Epistemic Things: Quality and its Consequences in Agri-Commodities Markets

This is a thought experiment on the consequences of technical rationality, the dominant epistemology of practice that tells us that “professional activity consists in instrumental problem solving made rigorous by the application of scientific theory and technique” (Schön 2017, 22). My aim is not to demonize technical rationality at the outset. Instead, I attempt to lay out the stakes of such a project when scaled beyond the confines of the spaces where experts conceive them. What happens when an “epistemic thing”—an unstable, experimental object of scientific research—is taken out of the controlled confines of the lab or the pages collated from a scientific symposium and introduced into the real world (Rheinberger 1997)? To borrow Anna Tsing’s phrasing, what happens when you increase the scale of an experiment without altering its frame for the differences encountered in the real world (Tsing 2015, 38; 2019, 506)?

Platypus in 2025

Welcome to Platypus in 2025! Last year, we published over 65 posts, almost half of which were also in a second language, and maintained a readership from 169 different countries.
