In 1911, engineers built the Titanic to survive the worst storms recorded in maritime history. They could not conceive of a threat they had not seen, so they failed to prepare for an unprecedented iceberg impact. This failure of imagination is known as the Lucretius Problem, named after the Roman poet who observed that humans believe the highest mountain they have ever seen must be the highest mountain in the world. The Bounds of Imagination explores the most dangerous flaw in modern risk management. Whether in financial markets, city planning, or corporate strategy, we consistently assume that the worst-case scenario of the past is the absolute limit for the future. This cognitive anchor blinds us to exponential threats and Black Swan events, leaving our systems deeply fragile to anything that breaks historical precedent. This book breaks down the architecture of strategic blindness. It offers powerful mental models to decouple your forecasting from historical data and stretch your imaginative capacity for catastrophe. Stop preparing for yesterday's crisis. Learn how to bypass the Lucretius Problem, anticipate the unprecedented, and engineer unshakeable resilience into your business and personal life.
