Been too many changes in the Guild over the last few years—just look at the messy rise of Intuitionism, or the growing numbers of women and colored people in the Guild, shoot, just look at Lila Mae, flux itself, three times cursed.
This is from Colson Whitehead's The Intuitionist. While I'm reading this book, I found that the author often wrote what characters said or thought without quotation marks and it confused me sometimes. Do you think the bolded sentence here is what Chuck said so that it didn't make any difference if it was put in the double quotation marks?
