Only Connect, by Ian Hamilton Finlay at Jupiter Artland, Edinburgh (one of my favourite places in the world). This Northumbrian limestone arch bridge is flanked by two milestones inscribed with the words 'only connect' - the last words in E.M. Forster’s novel Howards End.
In the novel, about fragments becoming whole and the difficulty of connecting our ordinary, conventional personalities with our transgressive, erotic desires, Margaret Schlegel implores of Henry Wilcox:
Mature as he was, she might yet be able to help him to the building of the rainbow bridge that should connect the prose in us with the passion without it. We are meaningless fragments, half monk, half beasts, unconnected arches that have never joined into man.
Only connect! That was the whole of her sermon. Only connect the prose and the passion, and both will be exalted, and human love will be seen at its height. Live in fragments no longer. Only connect and the beast and the monk, robbed of the isolation that is life to either, will die
