Our best understanding of neurology is like a blank map. As we grow and learn, we discover places on the map. We discover where the feelings on our fingers grow, and how to imitated the noises we hear. We discover the balance and coordination to walk and run and flip. Each place on the map is connected like pathways through a forest. The more we run along the path, the wider and more permanent it becomes.

The true power of the human mind is the ability of language. We have a superpower, to create an infinite number of sounds and shapes that arbitrarily describe an unlimited set of concepts. There are things we never dreamed of that our grandchildren will name, and it is this capacity to observe, remember, and describe things that has given rise to every great human accomplishment.

You learned the word "airport" as a place on your map. You never needed to connect it to the etymological history of the word, so you never needed to walk those paths. They were always there, which is why it seems obvious to you now, and also why a lot of people have the initial inclination to say "duh, of course." That's an expected response.

But we should all appreciate and marvel at the enormity of civilized history that has us here, scribing words on glass and light and copper, sending them instantaneously around the world, to discuss how the place where our flying machines engage in cooperative commerce and transport, how that concept is so mundane that you never even bothered to glance at the constituent words as separate concepts.

This is an amazing world, and we are all marvelous creatures. We are the absolute quintessence of stardust, and our progeny will look back on us as quaint.

Man, these are good drugs.
