They are both beautiful in their own way. Haskell is more pure, certainly, and closer to mathematical beauty, definitely. But the extraordinary flexibility of a lisp, which Clojure does immensely well, makes it more powerful than any language I've experienced for quickly expressing or manipulating an idea. Any program written in Clojure could eventually be refactored into another language, but its strength as a dynamic lisp makes it possible to really get to the heart of a problem and work out its solution without anything else getting in the way.
