Lisp, Scheme better than C for AI?

Hello. It seems everyone believes that Lisp-like languages are better than proceedural languages like C for AI. Why is that?

I suspect that recursion plays a part, but could use specific examples. Recursion is also possible in C, but not to the same degree or with the same ease, perhaps? Also, the distinctions between "live" processes and "dead" data have been said to be less clear in dialects of Lisp. Does this imply some valuable sorcery not easily wielded in C yet essential to AI advances? Examples and natural-language responses would be appreciated.

Perhaps a discussion of what's essential to AI and what's not (with respect to programming techniques and paradigms) is the thing I crave, something beyond the many FAQ-level responses.

You idiots know nothing about LISP. How about you just go the fuck back to /g/.

Lisp is better for mathematics in general. In C, 2*x is just an expression. You can't do anything with it. In lisp, (* 2 x) is an expression and a data structure. You can easily write a function to take its derivative or integral. You can also store it in a list to include it in vector and matrix operations. These are all very important in AI.
And that can't be done in Sepples? Only if you're an idiot.
