Philosophical Exploration of Existence and Perception

The following passage is an excerpt from a philosophical text discussing the nature of existence and perception:

Existence, as fundamentally understood, is often categorized into two realms: that which is perceived through the senses and that which lies beyond sensory experience. Philosophers contend that the essence of reality is often obscured by the limits of human perception. Indeed, the relationship between perception and reality is akin to a duality, where the tangible morphs into the abstract. Thus, the exploration of existence requires an examination not only of the seen but also of the unseen, prompting inquiries into the mental constructs that shape our understanding of reality.
