During the 18th and 19th centuries, the term "Jew" was sometimes used to refer to people who were not Jewish but were thought to share certain characteristics, such as greed, craftiness, or dishonesty. This usage was often derogatory and reflected anti-Semitic prejudices that existed within society at the time.
It is worth noting that Charles Dickens was a vocal advocate for social reform and a critic of societal injustices, including anti-Semitism. His portrayal of Fagin, while influenced by the context of the era, was also nuanced and sympathetic. Fagin is a complex character who exhibits a range of emotions, including vulnerability and compassion. Dickens intended to create a multidimensional character rather than perpetuate negative stereotypes.
Modern editions of "Oliver Twist" frequently provide context and commentary regarding the use of the term "Jew" to ensure that readers understand the historical context and the author's intention in using this language.
