Meaning & Analysis
Everything contributes to your benefit or advantage—whatever happens, it somehow serves your interests.
Insights
Opportunistic Gain
The proverb metaphorically suggests that some individuals or systems profit from all circumstances, interpreting or manipulating events so that they always serve their own ends.
Resourcefulness
It can also describe someone who is able to make use of whatever comes their way—turning even challenges or scraps into something useful or profitable, much like a miller grinding any grain brought to them.
Self-Serving Ideology
The phrase may point to how ideas, doctrines, or institutions are shaped to justify or support preexisting interests—everything becomes 'grist' for a particular agenda.
Mill as Metaphor for Exploitation
In early modern economies, a mill was a central institution where others brought grain to be ground for a fee. The proverb reflects the asymmetry in such relationships: those who own the mill (literal or figurative) always benefit, regardless of what is supplied.
Critique of Religious and Political Institutions
Writers like Gurnall and Fuller used the phrase critically, accusing religious figures or institutions (like the Pope or 'foreign casuists') of interpreting doctrine in ways that always reinforced their power or filled their coffers.
Universality of Utility in Rhetoric
The phrase also reflects a rhetorical phenomenon: how people can spin any situation—whether in politics, theology, or commerce—as supportive of their position. It anticipates modern notions of motivated reasoning or confirmation bias.
Rhetorical Devices
Metaphor
The mill metaphor provides a vivid image of continual processing and profit-making—transforming diverse inputs into consistent output for personal gain.
Idiomatic Expression
Its use of familiar agrarian imagery gives the phrase an idiomatic, colloquial tone, lending it both accessibility and durability in everyday language.
Irony (in context)
In many of its historical uses, the phrase is employed with irony, highlighting how systems or people cynically convert all things—even sins or suffering—into personal profit.
