Stephen Jay Gould Quote

Bowing to the reality of harried lives, Rudwick recognizes that not everyone will read every word of the meaty second section; he even explicitly gives us permission to skip if we get bogged down in the narrative. Readers absolutely must not do such a thing; it should be illegal. The publisher should lock up the last 60 pages, and deny access to anyone who doesn't pass a multiple-choice exam inserted into the book between parts two and three.
