“The upshot of all this is that we live in a universe whose age we can’t quite compute, surrounded by stars whose distances we don’t altogether know, filled with matter we can’t identify, operating in conformance with physical laws whose properties we don’t truly understand.”

An awful lot of England is slowly eroding, in ways that I find really distressing, and an awful lot of it is the hedgerows…

I refer of course to the soaring wonder of the age known as the Eiffel Tower. Never in history has a structure been more technologically advanced, materially obsolescent, and gloriously pointless all at the same time.

A significant fraction of thru-hikers reach Katahdin, then turn around and start back to Georgia. They just can’t stop walking, which kind of makes you wonder.

The remarkable position in which we find ourselves is that we don’t actually know what we actually know.

18th century scientists, the French in particular, seldom did things simply if an absurdly demanding alternative was available.

The world, you realize, is enormous in a way that only you and a small community of fellow hikers know. Planetary scale is your little secret.

Romans park their cars the way I would park if I had just spilled a beaker of hydrochloric acid on my lap.

There is no such thing, incidentally, as one kudo.

Every twenty minutes on the Appalachian Trail, Katz and I walked farther than the average American walks in a week. For 93 percent of all trips outside the home, for whatever distance or whatever purpose,

Not one of your pertinent ancestors was squashed, devoured, drowned, starved, stranded, stuck fast, untimely wounded, or otherwise deflected from its life’s quest of delivering a tiny charge of genetic material to the right partner at the right moment.

Christmas tree stands are the work of the devil and they want you dead.

I just use my life story as a kind of device on which to hang comic observations. It’s not my interest or instinct to tell the world anything pertinent about myself or my family.
