An idea

The senses

How the world gets in

Everything you know about the world arrived through a sense. Light, ripples of air, pressure, and drifting molecules all get turned into signals your brain can read, and it happens without you asking.

Each sense works completely differently, and each one has a surprise hiding in it. Touch came first. Smell takes a shortcut to memory. And most of what you call taste is actually your nose.
