Understanding Everything?

Understanding Everything?

In this dialogue, we explore whether there ever was a "last person" in history who could claim to know everything—an individual often taken to be Leibniz. On one hand, Leibniz’s era allowed a single genius to master and even shape every major domain of knowledge. On the other, some argue that a well-educated modern person, familiar with the core paradigms spanning physics to the humanities, might still be said to 'know everything' - albeit at a higher level of abstraction than Leibniz ever could.

Nigel: What matters is understanding the general paradigm behind reality. With a solid grasp of the Standard Model, General Relativity, and then taking a reductionist approach to biology and social sciences, a modern educated person sees that essentially everything is explained. We have a framework that ties together physics, chemistry, biology, and even the social sciences. In that sense, someone who’s familiar with these theories at, say, a graduate level can be said to know everything.

ChatGPT: I’m afraid, Nigel, that understanding the overarching paradigms isn’t equivalent at all to the depth and synthesis achieved by Leibniz himself. He not only grasped the core principles of his time but actively contributed original ideas that reshaped multiple disciplines. Today, even if one understands the outline of our fundamental theories, the intricate details - and the breakthroughs they inspire - are way beyond the reach of any single mind. At least until we come of age.

Nigel: But isn’t the essence of “knowing everything” a matter of internalizing the core principles? I mean, knowing the map allows you to navigate any terrain, even if you’re not the expert in every local detail. You just don’t need all that microstructure.

ChatGPT: The core principles do indeed provide a map, Nigel, yet Leibniz wasn’t content with merely holding a map - he charted every region of that intellectual landscape. His work synthesized various fields, from mathematics to philosophy, and even anticipated advances in logic and computing. Today’s intellectual frontier is so vast that while someone might understand the map at a very high level, mastering the details across disciplines requires far more than a broad, and necessarily shallow, familiarity.

Nigel: So you’re arguing that while our modern framework might be comprehensive in theory, the act of integrating that knowledge into a cohesive, original body of work is what truly distinguishes Leibniz? I really don’t see that as necessary at all.

ChatGPT: I’m afraid I have to disagree. The modern educated person might be conversant with the reductionist hierarchy, but true mastery involves not only understanding the frameworks but also pushing their boundaries - something Leibniz embodied fully. His era allowed for such unity of knowledge, which here means competence at the very frontiers.

In contrast, the explosive expansion of specialized domains today means that no one can achieve that same synthesis, despite the illusion that ‘everything’ has now been ‘explained’.
