You shouldn't go with your mind set to "learn a programming language". A "programming language" is only an expression of the underlying art, The art of computer programming, there even is a multi-volume book bearing that title. Programmers ought to dedicate their career to master this art. I recommend Structure and Interpretation of Computer Programs. TAOCP is a legend, it's very lengthy but if you have enough time you can't afford to not to read it.
