The author at first talks about what is being attempted, only to criticize in an almost poetic way right after. He says that even though those 32 chapters are meant to build a foundation, it means that by just filling something with words, in the end, you might create something too big and too filled to be easily enjoyed since reading is a complicated process, it's not just looking at something. The comparison is that if you see a castle and its many bricks, it's much easier to appreciate since you just have to look at the castle. But 32 chapters of words are meant to be read, which is an effort on its own.
