Why the most important philosopher of the 20th century was a plumber of concepts

In short: Mary Midgley did not publish her first book until age 59, yet she became the UK's fiercest critic of scientific pretension. She argued that philosophy is like plumbing: we only notice it when things go wrong, forcing us to pull up the floorboards and examine our most basic assumptions.

Midgley, who lived from 1919 to 2018, spent her career challenging the reductionist view that science could replace the humanities. She famously compared the world to a vast aquarium, arguing that we cannot view it as a whole from above. Instead, we must peer through multiple small windows, combining data from different angles to make sense of our habitat. Insisting that one's own window is the only valid perspective, she warned, leads to a distorted and incomplete understanding of reality.

Her work frequently targeted the 'scientific ideology' she saw in popular works by figures like Richard Dawkins. Midgley argued that such writers often projected political dramas—specifically a competitive, Thatcherite view of economics—onto evolutionary biology, presenting it as an impartial scientific truth. She maintained that this was not an attack on science itself, but a defense of it against dangerous misconstructions that treat genes as having ultimate power over human behavior.

Beyond her critiques, Midgley championed a holistic view of the human condition, emphasizing that we are, first and foremost, animals. She explored the moral status of non-human entities, arguing that we have ethical obligations to ecosystems and animals alike. Her philosophy, which deeply influenced literary figures like J.M. Coetzee, prioritized sympathy over the instrumental rationality often found in social contract theory. For Midgley, philosophy was never an ivory-tower pursuit; it was a necessary, everyday activity for navigating the complexities of being human.
