"It is the weight, not numbers of experiments that is to be regarded"
About this Quote
Newton is taking a quiet swing at the vanity metric of “busyness,” centuries before dashboards made it a lifestyle. “Weight” is doing heavy work here: not literal mass, but evidentiary force - experiments that bite into reality, discriminate between rival explanations, and survive repetition. “Numbers,” by contrast, suggests a pile-up of activity that can look impressive while proving very little. It’s an admonition against confusing volume with rigor, and it carries the voice of someone who watched the new science harden from gentlemanly curiosity into a method with standards.
The subtext is defensive as much as aspirational. Newton worked in an era when experimental philosophy was still competing with scholastic authority, alchemy, and speculative system-building. In that landscape, it was easy to claim victory by producing a parade of demonstrations. Newton’s line insists that not all experiments are equal; some are theatrics, some are noise, some are tweaks of the same idea. The “weight” test is a demand for experiments that constrain nature, not merely illustrate it.
There’s also a rhetorical move of moral economy: treat attention like a scarce resource. A few decisive, well-designed trials can carry more truth than a hundred incremental ones, especially if those hundred simply confirm what you already want to believe. Coming from the architect of the Principia’s austere reasoning, it’s a reminder that science’s prestige isn’t built on how much it does, but on how cleanly it compels assent.
