David's lessons, as well as Miss Murdstone's broader insistence that he be kept busy at all times, are a dark twist on the Victorian emphasis on personal responsibility and self-improvement. In both cases, the Murdstones' emphasis is less on the particular task being completed than it is on the work itself as a way of building character. This is consistent with an idea David repeatedly raises later in the novel—namely, that work is an inherently useful activity because it teaches qualities like patience and discipline. The Murdstones' actions, however, reveal the ways in which this ideology can be abused, or used to justify cruelty.
