A delusion is a fixed, unshakable belief based on insufficient evidence, distinct from illusions or doctrine. Authors like Mary Wollstonecraft Shelley examined its vulnerability, observing how such beliefs transform into new, equally erroneous convictions.
Valmiki associated delusion with ego, portraying it as a mirage dispelled by understanding, while John Wesley emphasized its ethical implications, cautioning against extremes arising from the rejection of spiritual truths. These viewpoints highlight delusion as both a psychological occurrence and a framework for exploring human challenges with reality, truth, and perception.
