Words about bridges

Bridges are always pleasing. 

A bridge over water is a bridge in its natural environment. A bridge over a road is an eccentric modern innovation. A bridge over a bridge is an exaggeration. 

Not all exaggerations are to be regretted. 

Not only can you walk over a bridge, you can walk under it. Thus, you can appreciate its beauties in two ways. 

But with a bridge over a bridge, you can simultaneously walk over and under a bridge, or under a bridge under a bridge, or over a bridge over a bridge (over whatever the under bridge goes over). This is so remarkable that I am remarking on it now. 

The world today is a complicated place, and full of not only bridges over bridges, but bridges over bridges while also being under other bridges, many of which are under other bridges, which are under other bridges, and so on. I am not sure if there is a limit to the number of bridges there should be in such arrangements. If two bridges is an exaggeration, three bridges is the same, only more so. Four bridges are even more more so, or even more interesting, or even more better, or even more gooder, or, at any rate, are certainly something. 

Complicated arrangements involving spaghetti junctions of bridges over bridges under bridges intersecting with still other bridges which stand in relation to yet more bridges do at least raise the prospect that one day, the architects and engineers will, using the medium of concrete and metal, manage to tie it all up into an exceedingly interesting knot. 

This is the end of my talk about bridges.
