Theorem of Berkeley

Theorem of Berkeley, also known as Berkeley's Principle, refers to the philosophical idea proposed by George Berkeley in the 18th century, which asserts that objects only exist when they are perceived. In essence, Berkeley argued that without someone to observe them, physical objects do not have an existence independent of our perception. This challenges traditional views of material reality, suggesting that our experiences and observations are fundamental to the existence of the world around us. His famous phrase, “esse est percipi,” means “to be is to be perceived,” encapsulating this concept.
