Final answer:
The 'gifted sister' faced discouragement from reading and writing due to societal expectations that women should focus on household duties, a reflection of the broader historical restrictions on women's education and literacy. This is exemplified in the experiences of both marginalized women and other oppressed groups throughout history, who faced barriers to education as a means of maintaining control by those in power.
Step-by-step explanation:
The "gifted sister" is discouraged from reading and writing because, throughout much of Western history, the societal expectations for women focused primarily on motherly and household duties. Women's access to education was severely limited, and it wasn't until the 19th century that they began attending college in significant numbers. This discouragement stemmed from long-standing beliefs that women's roles did not extend beyond the domestic sphere.
Furthermore, similar constraints were placed on other marginalized groups, such as enslaved Africans, who were often prevented from learning to read and write as a form of control. This not only hindered their ability to express themselves and share their stories but also served as a means to maintain existing power structures. Compelling figures like Virginia Woolf and Frederick Douglass highlight these struggles and the importance of access to education for self-expression and societal change.
It is clear from historical evidence that education and literacy have been essential to personal freedom and the ability to contribute to literature and culture. This is evident in Wheatley's and Douglass's writings, as they pushed against the oppressive norms of their times, showing the potential of those who were granted the opportunity to read and write freely.
