What would a skeptic like Hume say about the sound of a tree falling without an observer?

Hume, known for his skepticism and empiricism, would indeed express uncertainty regarding the sound of a tree falling without an observer. He believed that all knowledge is rooted in experience and that we can only be certain about things we have directly observed or experienced. In this context, without a perceiver to experience the sound, Hume would argue that we cannot definitively claim that a sound exists as it requires an observer’s experience for it to have meaning. This line of reasoning reflects his broader philosophical stance on the limits of human understanding and knowledge, emphasizing that without empirical evidence of an observer, the assertion of sound becomes questionable.
