      Meanings

      Noun

      1. the doctrine that reality or matter is made of discrete indivisible units

      Beyond the definition

      Atomism isn't about tiny bombs! It's a philosophical—and scientific—idea that everything is made up of separate, fundamental units. Think of building with LEGO bricks; atomism suggests the universe is built from basic "bricks" (which the Greeks called atoms) that combine in different ways to create everything we see.

      Historically, this was a way to explain how things change without needing gods or supernatural forces. Ancient Greek thinkers like Democritus and Leucippus were early proponents, arguing that matter was made from discrete particles and that many effects could be explained through their interactions. Today, while modern science shows atoms are made of smaller particles, the core idea—that reality can be understood by breaking things into their smallest useful components—remains central to much modern reasoning. You might also hear about "philosophical atomism" when discussing individualism or a focus on self-reliance.

        Some sociologists reject atomism because it ignores the way families, institutions, and culture shape people's choices.
