Understanding this quote
What it means
Science is not a fixed body of facts but an ongoing cycle of testing, revising, and correcting ideas. Every theory is provisional, held only until better evidence or clearer reasoning forces an update. Progress comes from admitting mistakes and improving upon them, not from declaring final truths. What we believe today may be adjusted tomorrow, and that willingness to revise is precisely what makes the method trustworthy rather than dogmatic.
Relevance to Max Planck
Planck embodied this himself. Trained in classical thermodynamics, he reluctantly introduced energy quanta in 1900 to fix blackbody radiation, overturning physics he had once defended. He spent decades refining quantum ideas alongside Einstein, Bohr, and Heisenberg, often revising his own positions. Awarded the 1918 Nobel Prize, he still insisted science advances funeral by funeral, as older minds yield to corrected theories, a view matching this quote exactly.
The era
Planck worked during a revolution in physics, roughly 1895 to 1947. Newtonian mechanics was cracking under relativity, radioactivity, and quantum discoveries. X-rays, the electron, and atomic structure all emerged within a generation. Two world wars disrupted German science, and Planck personally lost a son to Nazi execution. In that turbulent moment, treating scientific knowledge as permanently revisable was not abstract philosophy but a daily professional necessity shared across Berlin, Copenhagen, and Cambridge.
