us remember things.
I do believe that when reading and writing became more common, the older generation complained bitterly (as older generations always do) that the younger generation wouldn't be memorizing as much any more.
Well, memorizing is nice. I actually memorize poems that I like just because I want to, which makes me quite odd in this day and age. But I also like it a LOT that I can go on line and find all sorts of things that I don't have to memorize. I also live in a world where many print editions of lots of things are out there.
Oh, and I'll recommend "The Swerve" which is about the rediscovery of a specific lost ancient work, found by an itinerant Italian, who translated the latin into modern (as of then) Italian and brought an amazing lost text ("De Rerum Natura" back into common knowledge. Okay, so most of you have not ever read "The Swerve" or "De Rerum Natura", but trust me, your understanding of things depends on both of those. However, your life is not immeasurably impoverished because you've read neither one, but it would be greatly improved were you to read either of them.
My point is, that it's possible to be a complete human without having read any one specific work of literature. Or, as in the case of the OP, having memorized any of them.
