What key belief did David Hume accept from Berkeley?

David Hume accepted the key belief that perception is the key to establishing reality, which aligns closely with the philosophical ideas put forth by George Berkeley. Berkeley posited that the existence of objects is dependent on their being perceived; in essence, to be is to be perceived. Hume, while he expanded on Berkeley's ideas, also acknowledged the significant role perception plays in shaping our understanding of reality.

For Hume, reality is informed by experiences and perceptions, as he argued that knowledge is derived from sensory experiences. He was skeptical of the notion of an independent reality that exists outside of or apart from human perception. Instead, Hume's empiricism emphasizes the importance of sensory experiences in forming our ideas and understanding of the world. Thus, the emphasis on perception as fundamental to establishing reality demonstrates Hume's acceptance of Berkeley's views and furthers the discussion surrounding empiricism in philosophy.

The other options do not align with the shared beliefs between Hume and Berkeley. The idea that perception is not necessary for reality or that ideas exist separately from perception contradicts the fundamental tenets that both philosophers explore in their work. Similarly, the belief about God's perception being necessary for reality to exist reflects a more metaphysical view that isn't central to Hume’s philosophy as
