The phrase "If a tree falls in a forest and no one is around to hear it, does it make a sound?" is a philosophical thought experiment, not a quote from a specific author.

It's been attributed to various philosophers and writers throughout history, but no definitive origin has been established. Some believe it dates back to ancient Greek philosophers like Zeno of Elea.

While the question has no definitive answer, it's a compelling way to explore the nature of perception, sound, and reality itself.
