Niall Ferguson's book "Colossus" highlights the evolving nature of economics and politics, emphasizing the need for flexibility in thinking. The quote by Keynes, "when the facts change one must change their minds," serves as a reminder that successful decision-making requires adapting to new information and realities. In a world where data and circumstances frequently shift, clinging to outdated beliefs can lead to failure.

Ferguson's work encourages readers to embrace change and be open to revising their viewpoints as new facts emerge. This adaptability is essential not only in economics but also in navigating the complexities of modern governance and international relations. By recognizing the importance of adjusting one's stance in light of new evidence, individuals and leaders can better respond to the challenges they face.
