“I don’t know” sings the chorus in response as Madison Bycroft rallies off quip after quip the characteristics of a mollusc life-world while occupying a mollusc-like dress at the back of the mollusc-like stage. What this lecture-performance Soft Bodies (2017) addresses is a problem that faces much of the arts and humanities in the twenty-first century: a grappling with the ontological becomings and tentacular thinking, of those things that are and are not us. As science continues to illuminate the molecules and viruses that make up our bodies, we are plunged into a world where ideas about what distinguishes us as humans (and our understanding of what a human is) have become increasingly vague. As environmental philosopher Timothy Morton avows in solidarity, we are more non‑human than we are human. So what happens when boundaries that previously demarcated one thing from another disintegrate? And what do molluscs have to do with it?
