"...remind us of what we forgot."

I'm not sure exactly what to say about this quote, I'm having a hard time wrapping my head around it.  I suppose the part about the paintings confuse me the most.  Yes photographs do record things, so you often look back at things and remember something you had forgotten, but I feel a painting can work the same way.  You can forget what is in a painting just as much as you can forget what is in a photograph.  I also feel that paintings are more often open to wide interpretations than photographs are, because you're trying to see into someone's mind.  With a photo you are still seeing that person's intentions but they're represented in something that you recognize, not with images that where invented in the artist's mind.
