Lisp in nature is OO and can be nothing or anything. From this point
of view, lisp in itself maybe not considered as a language - it is
only a method and philosophy of constructing all things, and even can
reconstruct itself. Just as the praise by Bob Kanefsky and Julia
Ecklar in "Eternal Flame" [1]:

And God wrote in Lisp code every creature great and small.
Don't search the disk drive for man.c, when the listing's on the wall.
And when I watch the lightning burn unbelievers to a crisp,
I know God had six days to work. So he wrote it all in Lisp.
