In "Choose," Philip K. Dick explores the concept of paranoia, describing a paranoiac as someone who has lost their grasp on reality but in an astute and informed manner. This individual perceives the world as rife with intricate plots and conspiracies directed against them, leading to a heightened sense of vulnerability and mistrust.

Dick delves into the psychological turmoil that arises from such perceptions, illustrating how this mindset can distort one’s understanding of reality. The idea suggests that, in a chaotic and often intimidating world, the fears of the paranoid may reflect genuine societal issues, making their experience both tragic and somewhat relatable.
