First principles are fundamental truths or building blocks — the essential basics of any given situation, problem or context. Think of them like mathematical axioms, natural laws or foundational truths that govern how something works.
When you break something down to its foundational elements, you eliminate the noise and distractions of assumptions and analogies. You can see it more clearly for what it is. That clarity will lead you to deeper understanding and that in turn increases your odds of solving problems more effectively and in new and different ways.
It can be really easy to overlook first principles in typical daily discourse that is frequently noisy and full of distractions. We often tend to rely on analogies and past experiences. These mental shortcuts are efficient and feel effective, but they often further obscure the underlying truths that drive a situation.
Instead of digging down to the core elements, we gravitate toward what seems familiar or what has worked in the past, layering assumptions and comparisons on top of the issue at hand. This can make the real, fundamental truths harder to see — you see the forest, but not the trees.
The obvious thing to remember about first principles: They exist. They are context-specific, but they are always there. Ignoring them or underestimating their importance does not mean they disappear or become less important. If they were different, then the situation would not be what it is.
Remember that first principles are at play, no matter your context, and you can discover and understand what they are and how to work with them.
The first principle about first principles: They (always) exist.
