In "A Long Way Down," Nick Hornby explores the complexities of human emotion and the struggles of individuals grappling with their decisions. The quote, "Consistency is the extreme refuge of men," reflects the idea that sticking rigidly to certain behaviors or beliefs may not be the best path for personal growth or freedom. It suggests that true freedom lies in the ability to adapt and be open to change.

The protagonist's realization about this notion leads to a deeper understanding of personal responsibility and the impact of one’s choices. Wilde's influence presents a challenge for the characters, as they navigate their intertwined lives and confront their respective dilemmas, questioning the need for consistency in a world that often demands flexibility.
