The thing is, there is such a thing as "low witchcraft". I haven't read Penczak's work, but in general I think the important thing here is to understand that "high" and "low" don't mean "superior" and "inferior". It's a distinction between two different approaches to magic, not a value judgement.
High magic involves a lot of ceremony and ritual; it's very formal and very precise stuff. From the full title of that particular book (The Temple of High Witchcraft: Ceremonies, Spheres and The Witches' Qabalah), it sounds like "high witchcraft" is probably an accurate description of what the book's describing.
Low magic, on the other hand, is more sort of kitchen-witchy or hedge-witchy stuff. Informal, using what you have at hand, improvising as necessary and generally not involving a lot of full-scale ritual. It's not inferior to high magic; they just have different goals and different ways of achieving their goals.
Thanks for the reply it helps me understant this point of view. Sorry for the random quote I didn't check back when I wrote my reply thinking that it was for the first post.
