Esse est percipi is a philosophical principle coined by George Berkeley, meaning 'to be is to be perceived.' This idea underscores Berkeley's idealism and immaterialism, asserting that the existence of objects is dependent on their perception by a conscious mind. By emphasizing perception as the foundation of reality, this principle challenges the notion of an independent material world existing outside of our experiences.

Review Questions
How does esse est percipi challenge traditional materialist views regarding the existence of objects?
Esse est percipi directly challenges materialist views by arguing that objects do not exist independently from our perception. In materialism, reality is thought to exist regardless of whether it is perceived. However, Berkeley contends that without a perceiving mind, objects cannot be said to exist at all. This fundamental shift puts emphasis on the role of consciousness in defining reality.
Discuss the implications of esse est percipi on our understanding of knowledge and reality according to Berkeley's philosophy.
The implications of esse est percipi suggest that knowledge is inherently tied to perception. According to Berkeley, if something cannot be perceived, it cannot be known or considered real. This leads to a radical understanding of reality where all knowledge stems from sensory experiences. It shifts the focus from an objective world independent of us to one that is created and sustained through our interactions with it.
Evaluate how esse est percipi influences contemporary discussions about reality and perception in modern philosophy.
Esse est percipi has significantly influenced contemporary philosophy by prompting discussions about the nature of reality in relation to human consciousness. Modern thinkers often grapple with ideas of subjectivity versus objectivity and how perception shapes our understanding of existence. This principle leads to inquiries about virtual realities and how technology mediates our experiences, making us question what is truly 'real' in an increasingly mediated world.

The doctrine that material substance does not exist and that all reality is made up of ideas or perceptions, which are fundamentally mental.
Perception: The process through which individuals interpret sensory information, which, according to Berkeley, is essential for the existence of objects.
