The quote "If you break little promises, you'll break big ones" from Cormac McCarthy's novel "The Road" emphasizes the importance of integrity and the way small actions can reflect one’s character. It suggests that minor commitments may seem insignificant, but they lay the groundwork for larger obligations. When someone disregards small promises, it can lead to a pattern of unreliable behavior that affects significant relationships and responsibilities.

This idea speaks to the moral landscape of the novel, highlighting the struggle for survival amidst harsh circumstances. In a world where trust and loyalty are critical, adhering to even the smallest promises can reinforce one’s moral compass. Through this lens, McCarthy illustrates how maintaining one’s integrity can be pivotal in navigating the complexities of life, especially in dire situations.
