How does silver symbolize corruption in Nostromo?

In Joseph Conrad’s Nostromo, silver serves as the central symbol around which the novel is organized, representing the corrupting influence of ambition.1

The silver, which constitutes the wealth of the fictional South American republic, acts as a catalyst for moral disaster among the characters. Conrad illustrates that the pursuit of this wealth—whether driven by simple greed or by idealistic desires for reform and justice—inevitably leads to corruption. The novel suggests that the nobler the initial ambition, the more profound the character's eventual self-disgust upon realizing their moral compromise. Ultimately, the silver functions as a destructive force that exposes the inherent vulnerability of human ideals when confronted with the corrupting power of material wealth.1
