Reason lets us know the unreachable — the Earth's interior as a parable of indirect knowledge: no human has been within ~6,000 km of the Earth's centre (the deepest borehole, Kola, barely scratched ~12 km), yet we confidently describe a solid inner core, a liquid outer core and a solid mantle. How? Purely by inference: seismic P-waves bend and S-waves are blocked by the liquid outer core, creating "shadow zones" on the surface — and from that absence of a signal we deduce the state of matter thousands of kilometres down. A vivid illustration that knowledge advances not only by seeing but by reasoning from indirect evidence (the "shadow" is as informative as the wave) — apt for "disinterested intellectual curiosity is the lifeblood of civilisation" (1995) and "mathematics is the music of reason" (2023). The same logic underlies how we "see" black holes, dark matter, or a patient's heart through an ECG: the mind reconstructs what the eye can never reach.
