"We should remember that there was once a discipline called natural philosophy. Unfortunately, this discipline seems not to exist today. It has been renamed science, but science of today is in danger of losing much of the natural philosophy aspect"
About this Quote
Alfven’s lament isn’t nostalgia for powdered wigs; it’s a warning about what gets amputated when a field professionalizes. “Natural philosophy” evokes a mode of inquiry that was comfortable asking first-order questions: What is this phenomenon, really? What assumptions are we smuggling in? The rebrand to “science” signals triumph and institutional power, but Alfven suggests that victory comes with a quiet narrowing of imagination.
The subtext is aimed at a culture of research that prizes technique over understanding. In modern labs, competence often means mastering instruments, simulations, and statistical pipelines. That machinery is indispensable, yet it can also turn scientists into highly trained operators inside inherited frameworks. Alfven, a Nobel-winning plasma physicist who sometimes found himself at odds with prevailing astrophysical models, is pointing at the sociology of consensus: funding incentives, publication pressures, and disciplinary gatekeeping reward incremental, model-confirming work more reliably than foundational skepticism.
What makes the line work rhetorically is the contrast between names. “Science” sounds definitive, even finished; “natural philosophy” sounds provisional, human-scaled, willing to live with uncertainty while still reaching for coherence. Alfven is not anti-empirical. He’s defending a lost temperament: the habit of treating equations and models as tools rather than metaphysics, and of remembering that nature doesn’t owe us tidy categories.
Read in context, it’s also a plea for intellectual breadth. When science loses its philosophical nerve, it risks becoming brilliant at measurement and timid about meaning - and that’s how a civilization can keep innovating while slowly forgetting what its knowledge is for.
