 The spirit of the age is always changing in accordance with fashion and as C.S. Lewis, that great disciple of Chesterton said, fashions are always coming and going, but mostly going. In other words, if something is fashionable, one thing you can be fairly sure of is going to be unfashionable soon. If something is up to date, you can be fairly sure it's going to be out of date soon. The things that matter are the perennial things, the permanent things, the unchanging things. And what is the one obvious unchanging thing moving through human history? It's the Catholic Church. And G.K. Chesterton says that the Catholic Church is the one institution that's been thinking about thinking for 2,000 years. Even if the institution has been thinking about thinking for 2,000 years, we should probably listen to it. We might learn something.
