How to have a vibrant intellectual life in NYC?

Hi, this is my last year in NYC before going back to Europe. I am increasingly turned off by how consumerism is prevalent in the city and would like to focus on things that make my brain happy.

Here is what I do already : – I created a museum schedule to go visit a different museum once or twice a week – I am an avid user of the NY public library and read a lot (both paper books and books from Libby) – I joined a book club – I sometimes go to language meetups – I signed up to an online class on American history.

I feel that I would like to go to places where you can talk about philosophy or literature. I would also like to attend more classical music or opera shows. I am open to any other recommendation.

Thanks in advance for your advice!
