"Common sense says that chairs and tables exist independently of whether anyone happens to perceive them or not"

This quote by Charles D. Broad is recommending that sound judgment determines that physical things exist separately of whether they are perceived by someone. This suggests that even if nobody is around to observe a chair or a table, they still exist in the real world. This is a crucial principle to understand, as it implies that physical items exist in such a way that is independent of our very own assumption. It likewise indicates that physical objects have an existence that is different from our own. This quote is a tip that physical items exist in the world no matter whether or not we understand them. It is a suggestion that the real world is not depending on our own perception, which physical items exist individually of our very own.
