Daily Inspiration Quote by David Ricardo

"In stating the principles which regulate exchangeable value and price, we should carefully distinguish between those variations which belong to the commodity itself, and those which are occasioned by a variation in the medium in which value is estimated, or price expressed"

About this Quote

Ricardo is doing something deceptively radical here: he’s insisting that “price” is not the same object as “value,” and that our instruments for measuring the economy can distort what we think we’re seeing. It’s the early-19th-century version of “don’t confuse the signal with the noise,” aimed at a public argument that was noisy in the extreme: Britain was wrestling with paper money, bullion convertibility, wartime finance, and the political blame game over rising prices.

The intent is methodological discipline. If you’re trying to explain why bread costs more, you need to separate two very different stories. One is real: something changed in bread’s conditions of production or scarcity. The other is monetary: the yardstick itself shrank or stretched because the “medium” (currency, credit, the unit of account) shifted. Ricardo is warning that without this distinction, you’ll misdiagnose inflation as greed, or treat genuine scarcity as a monetary illusion.

The subtext is a quiet jab at sloppy political economy and convenient rhetoric. People reach for price movements because they’re visible and emotionally legible; Ricardo says visibility is precisely the problem. Prices are mediated facts, not raw ones. That stance also smuggles in a moral claim: policy should be based on correct attribution, not populist intuition.

Contextually, this fits Ricardo’s larger project of making economics a rigorous science of relations - and it shows his signature move: turn a moralized debate into an analytical one by interrogating the measurement itself.
