Return to first principles
Meaning
To go back to the most fundamental truths and assumptions of a subject or problem, rather than reasoning by analogy or previous conclusions.
Origin
The concept of 'first principles' has roots stretching back to ancient Greece, most notably with Aristotle. He championed the idea of 'protê archê'—a first beginning or fundamental principle—suggesting that to truly understand anything, one must break it down to its most basic, foundational truths, those upon which all other deductions are built. This wasn't just a philosophical exercise; it was a rigorous method for building knowledge and argument from the ground up, stripping away assumptions to reveal the irreducible elements. Over centuries, this powerful analytical tool became a cornerstone of scientific inquiry and logical reasoning, profoundly influencing Western thought. While the exact phrase has seen various forms, its core meaning, popularized in modern times by innovators like Elon Musk, remains a call to unearth those elemental truths before attempting to solve complex problems.
Examples
