Hoare’s Law“Inside every large program is a small program struggling to get out.”
Tony Hoare
This quote, also known as Hoare’s Law, offers a wry yet incisive commentary on the nature of software development. It suggests that beneath the surface of any sprawling codebase lies a simpler, more elegant design—a fundamental idea often obscured by layers of unnecessary complexity. The insight serves as a reminder that while large programs tend to accumulate superfluous features over time, the true art of programming is in distilling problems to their simplest form.

Transcripts of round-tables at a conference; it’s mostly known as the source of Tony Hoare’s Law, “inside every large program there is a small program trying to get out.”

“What is the central core of the subject [computer science]? What is it that distinguishes it from the separate subjects with which it is related? What is the linking thread which gathers these disparate branches into a single discipline? My answer to these questions is simple—it is the art of programming a computer.”
