"All the choir of heaven and furniture of earth - in a word, all those bodies which compose the frame of the world - have not any subsistence without a mind"

This quote by George Berkeley is a philosophical statement about the relationship in between the physical world and the psychological world. He is suggesting that the physical world, that includes all the celestial bodies, the elements of the earth, and the whole universe, can not exist without a mind. He is suggesting that the physical world depends on the psychological world, and that the physical world is an item of the mental world. This idea is referred to as subjective idealism, which mentions that the real world is an item of the mind which the real world is not an independent entity. Berkeley's quote recommends that the real world is a product of the mind, and that the real world is not an independent entity. This concept is important because it suggests that the real world is not an outright truth, but rather an item of the mind. Berkeley's quote is a suggestion that the real world is not an absolute truth, however rather a product of the psychological world.
