> No, please. OOP does not have a monopoly on abstraction, encapsulation, modularity, etc.

Exactly. One of the best resources on those things that I've read/watched is MIT's SICP (both books and video lectures). And it is about everything else than OOP.

Abstraction, encapsulation and modularity are bigger than any programming paradigm. They are orthogonal to OOP, et al., you think about them separately. Moreover, they transcend the programming itself, and serve as one of the most basic mental tools humans can use for everything in their lives.
