The plot of The World of Null-A is complicated. In order to show the advantages of non-Aristotelian logic, van Vogt places his ultimate Null-A philosopher Gosseyn under extreme stress, including enduring his own horrible murder. Gosseyn is flung from one suspenseful situation to another; the suspense simultaneously forces Gosseyn to use to the utmost his Null-A skills and serves to maintain reader interest. In addition, by putting forth a clear philosophical background for the action of the novel, van Vogt manages to keep his imaginative plot twists clear. Gosseyn's "Null-A pause" not only allows him to put his situation into clear perspective, it allows him to clarify the situation for readers, as well, without long, tedious explanations that would distract one from the plot.
