The ocean makes human certainty look appropriately small.

Standing at the edge of that much water does something to certainty. All the things you were sure about, all the fixed opinions, all the outcomes you were insisting on: they do not disappear, they just stop seeming so obviously central. Scale is a kind of argument that does not require words.

If you are locked into a position and cannot loosen it, go somewhere enormous. You may come back with the same view and hold it more lightly, which is usually the more useful change anyway.
