From What Is to What If is a book by Transition Network founder Rob Hopkins that argues for reclaiming collective imagination to solve environmental and social crises. It advocates moving from stagnant, current realities ("what is") to a future-focused, imaginative mindset ("what if"), highlighting community-driven, creative solutions to foster rapid, positive change. 

Key Themes and Concepts:

• Reclaiming Imagination: Hopkins argues that modern society has suffered an "imaginative decline," leaving us unable to envision better alternatives to the status quo.
• The Power of "What If": The book encourages asking "what if" questions to spark creative thinking about alternative futures, such as "What if we took play seriously?" or "What if schools nurtured imagination?".
• Actionable Examples: It showcases examples of community-led initiatives—from local energy projects in Totnes, England, to creative urban planning—demonstrating that tangible change is possible.
• Overcoming Apathy: It acts as a call to action to move beyond just analyzing current crises (the "what is") and instead to actively design and build a desirable future (the "what if").
• Focus on the Local: The book emphasizes that profound change can begin in local communities and through individual, collective actions. 

The book is aimed at anyone looking to address the climate crisis and other global challenges through a more human, creative, and proactive approach.
