"The goal of physiological research is functional nature"
About this Quote
A small sentence with a sharp provocation: physiology is not in the business of cataloging parts, but of explaining purpose. Hess, a Nobel-winning physiologist who mapped brain function with the pragmatism of a laboratory engineer, is staking out an intellectual border. “Functional nature” is a quiet rebuke to the kind of science that treats the body like a museum collection: beautiful specimens, impeccable labels, little sense of what any of it does when life is actually happening.
The intent is methodological. Hess is compressing a whole research ethic into five words: if your experiment can’t connect mechanism to action - regulation, behavior, adaptation - you haven’t reached the target. The phrase also smuggles in a larger philosophical bet. “Nature” here isn’t romantic scenery; it’s the living system as it operates, improvises, and self-stabilizes. Function becomes the bridge between molecules and meaning, between anatomy and the organism’s everyday negotiation with the world.
Subtextually, Hess is arguing for integration over reduction: physiology as a discipline that insists on feedback loops, control systems, and the coordination of organs and neural circuits. Coming from a 20th-century context obsessed with localization (which brain bit does what?) and increasingly tempted by pure biochemistry, it reads as a corrective: don’t lose the organism in the microscope. It’s also a subtle claim to relevance. Functional explanations are the ones that travel - into medicine, psychology, and any science that has to answer the question patients and societies actually ask: what is this for, and what happens when it fails?
