The essence of reality is defined by its persistence; it remains unchanged regardless of our beliefs. This quote emphasizes that our perceptions and understanding can shift, but the fundamental nature of reality is unaffected by our beliefs or disbeliefs. The statement implies that truths exist independently of our acknowledgment or acceptance. Reality will continue to unfold irrespective of our personal convictions.

In Philip K. Dick's "I Hope I Shall Arrive Soon," this concept suggests that individuals must confront the world as it is, not necessarily how they wish it to be. This perspective encourages a deeper exploration of the nature of existence and challenges us to question our assumptions, emphasizing a need for grounding in the actual world, which stands firm despite our subjective experiences.
