Also, near the conclusion of the story, the "fits" of Silas seem to have subsided. This makes sense because since the bachelor weaver has recovered and Eppie has opened his eyes to the reality of the world again, his soul is no longer separate from his body. While before, his soul was exiled and held in a purgatory of sorts before he found Eppie, now his spirit is alive and well, living in the present. Yet he still has relapses, suggesting that the fifteen years of self-torture have left permanent scars on his troubled soul.

One lesser theme of the book is in regards to the Cass family. Eliot, through her portrayal of Godfrey and Dunstan as wealthy, selfish scoundrels who try to use one another and others to their personal advantage, asserts that the upper class has damaged society. While the Cass family, thinking that their wealth gives them undue privilege and rights to property (Godfrey’s attempt to seize Eppie from Silas), seems incredibly egocentric, Silas, representing the lower class, is seen as a humble victim of class bias.

Even religion is indicted in the novel, showed to be unjust and hypocritical during the casting of lots which finds Silas guilty. Yet the face of faith is recovered towards the end, following Silas’s return to church and baptism of Eppie. No matter what the circumstances, Silas learns that his faith can always be a pillar of strength.
