That description is one that Faber gives to Montag as one of the reasons that books are so wonderful. It's an interesting phrase, and takes a bit of thinking to get your brain around. Faber calls it quality. He states that a book has "features. This book can go under the microscope...The more pores, the more truthfully recorded details of life per square inch you can get on a sheet of paper." What he means by this is that books record every detail of life, even the ugly ones. Compare it to a magazine picture of a model, versus a snapshot you take of a friend. The model is gorgeous, make-up on, buffed, shined, air-brushed-and hence, not a true reflection of life. How many people actually look like that? Now consider your snapshot of a friend. You can see their pores, blemishes, and shiny spots-but at least it's real. Faber is stating that books don't shy away from presenting real life, and as a result, they have more quality. We can learn more from them because they are truthful and non-deceptive. He goes on to say that "the good writers touch life often. The mediocre ones run a quick hand over her." So, good writers do a good job of relaying life and all that it has to offer-good and bad. In Montag's society, nothing presented is quality or real; it's all fake, surface, dense, and shallow. Nothing has pores, nothing is real, and as a result, everyone is miserable. I hope that helps explain it a bit!
