If the Library of Alexandria had survived, the world would be a very different place. All that knowledge—philosophy, mathematics, astronomy, medicine—would have been passed down from generation to generation, not lost to fire and war. Scientific progress would have accelerated; we might have discovered modern physics and biology centuries earlier, and our political ideas could have evolved with a stronger emphasis on empirical evidence. The very notion of education and scholarship would be more universal, shaping a culture that values learning as a shared public good. In short, we would likely make far more enlightened choices today, guided by a richer tapestry of ancient wisdom and a deeper appreciation for the fragile threads that hold our collective memory together.
