What books to read thats good for Philosophy?

Books that can deepen my understanding, not only to God also, but also to my fellow humans ykwim? I've realized that I spend too much time on my phone, so I want to start reading more.

I also wanted to ask if the works of Fyodor Dostoevsky are okay to read. I'm asking because I assumed there might be some books that I probably shouldn't read as an Orthodox Christian, so I wanted to hear your thoughts or recommendations. (Would appreciate books by him too, and thank you!)
