Grids according to Boone allow for legibility, repetition and consistency. With grids, viewers easily grab the contents of the design as their attention is easily grabbed thus ensuring easy connection with the design. He equates grids to grammar in visual composition in which grids help in the design by acting as the grammar tool of telling a story in which the objective is easily executed and space defined.
He also mentions that he has used grids severally in his design works. However, the fact that he argues that grids hinder originality by restraining creativity is not logical because he does not expand on this argument. He should explain why he thinks that grids hinder originality not just mentioning it in the midst of so much praising of grids.
