Science Quote by Max Planck

"We have no right to assume that any physical laws exist, or if they have existed up until now, that they will continue to exist in a similar manner in the future"

About this Quote

Planck drops a quiet bomb on the fantasy that science is a catalog of eternal rules. Coming from the architect of quantum theory, the line reads less like philosophical hand-wringing than a disciplinary warning: the “laws” we cherish are hard-won summaries of experience, not guarantees stamped into the universe. The phrase “no right” is doing a lot of work. It’s moral language smuggled into epistemology, reminding scientists that certainty can become an ethical lapse - a kind of intellectual overreach.

The subtext is shaped by Planck’s historical moment. By the early 20th century, classical physics had started to look like an impressive, brittle edifice: Newton worked until he didn’t; Maxwell explained light until blackbody radiation refused to cooperate. Quantum mechanics didn’t just add new facts; it changed the rules of what counts as a “law,” replacing clockwork predictability with probabilities and measurement limits. Planck’s skepticism isn’t anti-science; it’s what science looks like when it’s honest about its own revolutions.

The quote also anticipates a modern discomfort: we live off the assumption of stability. Engineering, forecasting, even everyday planning depends on the idea that tomorrow will rhyme with today. Planck points out that this is an enormously useful habit, not a metaphysical entitlement. He’s not inviting nihilism; he’s insisting on humility as a method. Scientific progress, in his telling, isn’t the march toward certainty - it’s the disciplined management of doubt.
