Only viewable if you have a connection that's faster

Yes, section 1.6 describes "evalquote", which is the "universal"
LISP function of the section's title. Page 13 defines evalquote:
evalquote[fn;x] = apply[fn;x;NIL]
and the lower half of the page defines apply and eval.
I didn't really "get" LISP until I read that little book
(106 pages, three dollars!), probably in the early 1980's.
I suspect that this may have been because of the only other
LISP book I had read at the time. I vaguely recall it as
being a book that had a few FORTRAN-ish programs, written
in LISP. I don't remember other details of that book.
