You can curse the darkness, or you can light a candle […] If young people today do not know of events or artists or thinkers or works that you think they would benefit from knowing, you can tell them. That’s one of the main things writers are for.

A funny thing happened as I was reading this passage from Alan Jacobs' brief article about (un)knowing: my five-year-old was listening to We’ll Meet Again, the 1939 hit that has, c/o Gravity Falls, become his favorite tune. Funny how culture works.
