" True consistency, that of the prudent and the wise, is to act in conformity with circumstances and not to act always the same way under a change of circumstances. "
- John C. Calhoun

In simple terms, the quote suggests that true consistency is about adapting one's actions according to changing circumstances rather than sticking rigidly to a single approach regardless of what happens. It implies that being wise and prudent means having the flexibility to change strategies when necessary while still maintaining an underlying principle or goal.

At its core, this statement challenges the common notion that steadfast adherence to a set course of action equates to true consistency. Instead, it advocates for an understanding of circumstances and the ability to adjust behavior accordingly in order to achieve better outcomes. This perspective encourages individuals to be thoughtful and responsive to their environment rather than blindly following a fixed path. It promotes the idea that wisdom lies in recognizing when and how to adapt one’s approach without losing sight of what is ultimately important.

John C. Calhoun, an influential political theorist and statesman from South Carolina, delivered this quote during his career as a U.S. Representative and Senator. He was known for his controversial views on nullification and slavery, but also contributed significant ideas about government and society that continue to be debated today. His statement on consistency reflects his broader philosophy of pragmatism and flexibility in governance and personal conduct.
