2 or 3 things

I thought that "2 or 3 things I know about her" was an attempt to reveal somewhat how little we know about the world. In the beginning, when the voiceovers began, Godard tells us a few simplistic facts about Juliette, which somehow got drilled into all of our brains. Throughout the film he exposes that Juliette is in fact much more than this. She is a mother, a prostitute, a wife, a philosopher... etc. She is a multifaceted person that cannot be fully understood by a few facts or glimpses.

I think this plays well into the idea described as "her" being Paris: a city can be glimpsed at, visited, and even lived in but it is difficult for one to know all there is in the city and all the sides it has.

This also plays into the modern, political ideals of French New Wave. How is it possible for one person to observe a thing and fully understand it? I think that is what the film was attepmting to explore.
