It would seem you are completely clueless about Lisp, so there isn't much
point discussing this statement.

If you are at all interested in programming languages as such I think you'd be
well rewarded if you at least have a good look at scheme (CL is also well
worth some study). Whether one likes scheme as a practical programming
language or not, I think it's difficult not to find it invaluable as a sort of
conceptual assembler. A great number of programming paradigms can be concisely
and illuminatingly expressed and reasoned about using just a handful of the
powerful abstractions such as, e.g. (properly tail recursive) lambda, call/cc,
cons, symbols and defmacro¹.


In addition, the majority of excellent computer science books I've come across
(and many great articles) use scheme or some other lisp and, even better, are
often freely available on the web²!

¹ defmacro is not part of the standard, but generally available, and, I think,
  much easier conceptualized than scheme's more complicated hygenic macro
  systems.
