No one can measure the distance to
the horizon, only the distance from it.
The horizon doesn't exist, but it must.
One must determine the place between
high tide and low tide, then measure up
to the point from which one wants to
envisage the horizon, which is a fiction
resting on a line by the angle above sea-
level from which one overlooks ocean. Okay?
There is no fixed point to the horizon,
or to measurement, or to looking at the sea,
or even to living next to the ocean, a notion.
There is a sea, a coast, two tides, a triangle
tied to a plane on a sphere. Let's grant these,
please. There is no horizon, except insofar,
so far, as something seems to end out there
a certain uncertain distance from here. There
is no distance like show-distance to the horizon
because if one travels it, the distance, then
the horizon will have moved away. Nonetheless,
one is free to measure by the sea. They can't
take that away from thee. One is free to look
and to say, "Look, there's the horizon." Okay?
