One night in September I gave a talk to an audience of one hundred in a parish of Saskatoon, Canada. The next day I went on to teach eighty of those parishioners on the same theme. My topic, given the numbers involved and their enthusiasm, might surprise you: it was poetry.

People think that poetry has fallen out of fashion. In an age of social media, all art forms are evolving with the reduced attention spans of their audience. For poetry, this presents a particular problem. You see, poetry is slow. It is often about stillness. It requires very pure attention.
