In "The Ingenious Gentleman Don Quijote of La Mancha," Miguel de Cervantes illustrates a character deeply engrossed in reading. His commitment is so intense that he sacrifices sleep, choosing to read throughout the night while struggling to keep up with the day. This immense dedication leads to a blurring of reality, affecting his ability to think clearly.

The quote highlights the consequences of obsession with literature, suggesting that while knowledge can be enriching, it may also distort one’s judgment. Ultimately, the protagonist's fervent engagement with his books drives him to lose touch with reality, showcasing the fine line between passion and obsession.
