In Victor Hugo's "Les Miserables," the idea of a skeptic being drawn to a believer is likened to the concept of complementary colors in art. Just as complementary colors enhance each other, the contrast between belief and skepticism can create a dynamic interaction. This relationship illustrates how opposites can attract and enrich understanding.

The quote suggests that the elements we lack or oppose can often captivate our interest. This attraction to what we do not possess or believe in points to a deeper human tendency to explore and challenge our own perspectives, ultimately leading to personal growth and enlightenment.
