Themes

Folk Remedies Versus Science

Throughout the text, Murphy emphasizes the transitional state of the medical profession in 1793. While doctors at the end of the 18th century are beginning to seek out clear, science-backed understandings of diseases, they continue to prescribe treatments based on folk traditions, some of which date back to the ancient world. Murphy indicates that the transition is not necessarily a smooth one, as it brings controversies and disagreements that go unresolved. The arguments within the College of Physicians as to whether the sickness is yellow fever or whether it is imported are fundamentally divisive and only decided by majority vote, rather than by any scientific testing. It ultimately leads Benjamin Rush to resign from the College.

The strong adherence to folk remedies also opens the door to controversial cures like Rush’s “Ten-and-Ten,” which many found to be excessive. Anyone claiming a cure could potentially be taken seriously, leading to “quack” doctors and treatments, many of which Murphy describes. Efforts to treat the fever were essentially a guessing game, guided by the reigning principles of humoral theory rooted in ancient Greece. Balancing the body’s four humors, which were “phlegm, choler, bile, and blood” (15), required little understanding of human anatomy or physiology. The part of Rush’s cure that involves bloodletting is taught to volunteers from the Free African Society, who then perform the procedure over 800 times.

For Murphy, medical developments in the 1800s and early 1900s that determine the mosquito as the cause of yellow fever are a major step toward controlling the disease. It guarantees that a situation identical to the one in Philadelphia in 1793 will not be easily replicated. The discovery of bacteria and viruses in the late 1800s permanently upends humoral theory, allowing ideas regarding the relationship between mosquitoes and disease to be adequately explored. While Murphy clearly sees that scientific advancements are beneficial, he also notes that they are not without problems, as demonstrated by the indiscriminate spraying of the pesticide DDT in the 1940s.

Racial Dynamics in Philadelphia

Murphy examines much of the yellow fever epidemic in terms of racial dynamics, which at times were tense. The outbreak serves as a way for Murphy to explore the challenging and changing role of African Americans in Philadelphia in 1793. At the height of the outbreak, the Free African Society agrees to volunteer its services to help fever patients. Public reception to their assistance, however, is mixed, as reports spread that African American nurses are preying on the sick and dying by raising prices due to high demand. Although Mayor Clarkson appears to settle the matter by explaining that the higher prices are due to white patients outbidding one another, it resurfaces in the aftermath of the outbreak in Matthew Carey’s book.

While Absalom Jones and Richard Allen write a rebuttal to Carey that Murphy praises as “a remarkable essay, tightly argued and organized, passionate and unrelenting” (118), they remain the target of racial hostility that is not easily quelled. The city still has a small population of slaves, and free African Americans are only just starting to forge a strong community, establishing the Free African Society, for example, in 1787. However, Matthew Carey’s efforts to address and ameliorate the situation also demonstrate that the voices of some of the city’s more prominent African Americans are being taken seriously. Although Carey’s actions are inadequate, they reveal the complexity of racial dynamics in Philadelphia. Racism is very much present, but African Americans are making substantial inroads across various fields.

Murphy also stresses the extent to which the Free African Society is critical to the city’s efforts to manage the epidemic. The city would have been at a significant disadvantage had the Free African Society not agreed to help Mayor Clarkson. Murphy explains that all African Americans in Philadelphia at the time “had suffered in one way or another at the hands of whites, some of them in appalling ways” (44). Despite the many continued injustices against them, including the fact that some of them were enslaved, they make great sacrifices to care for the sick and dying during the epidemic. Murphy calls them a “battalion of heroes” (55).

Urban Class Structure

The social structure of Philadelphia in 1793 plays a major role in determining how the yellow fever epidemic plays out. Those who initially flee the city at the onset of the outbreak are generally wealthier people, or those who can afford to leave. It is the poor and destitute that are primarily left behind, except for a few individuals of means who choose to stay. Murphy consistently emphasizes the plight of poor people as the fever spreads, viewing those who stay to help them as courageous. For Murphy, a large part of their heroic actions stems from the fact that they are helping the destitute and disadvantaged.

Throughout the book, Murphy demonstrates the extent to which urban life in the young nation is defined by social and economic status. Most of the wealthiest citizens leave almost immediately, which includes many members of government. Even before the fever, there are very few organizations and individuals dedicated to helping the city’s large underclass. As thousands of people flee, the fever puts this group in an even more vulnerable position. Mayor Clarkson describes the situation as “grave” to the Guardians and Overseers of the poor, which at the start of the epidemic is “the only official group then dealing with the poor of Philadelphia” (38).

Murphy makes clear that those who step in to help the poor are mostly from the middle classes. Those with wealth and power do very little to help until the fever has dissipated, creating bigger problems by leaving. The end of the epidemic does little to change the heavy class stratification of the city, and the poor continue to be at risk.

Leadership in a Crisis

One of the main themes in Murphy’s work is how the yellow fever outbreak is handled by those in leadership positions. Most members of the federal, state, and local government abandon Philadelphia as the fever spreads, opening a power vacuum in the city. When Governor Mifflin leaves, he hands the problem over to Mayor Clarkson, who has no real power or authority. Although Clarkson must illegally create the committee to oversee the epidemic, Murphy praises his efforts and emphasizes “the courage of the committee members” (68), which is made even more commendable by the fact that “the majority of them are not wealthy” (68). For Murphy, the actions taken by Clarkson and the committee were both necessary and heroic. He views seizing control in a time of crisis as a justifiable act, even if the power grab is illegal.

When George Washington leaves in September, he creates another problem, opening up the question as to whether Congress can meet to enact legislation. The major figures in the federal government disagree over whether Congress can assemble outside of Philadelphia. Alexander Hamilton feels that they can, while Thomas Jefferson and James Madison believe doing so is unconstitutional. The issue stems from the actions of English monarchs, who would take Parliament to a remote location that was inaccessible to those challenging particular legislation. The US Constitution therefore gave special consideration to Congress’s location, which was bound to enact laws within the limits of the nation’s capital. Murphy indicates that their inability to resolve the question during the epidemic gives people like Matthew Clarkson, Stephen Girard, and Israel Israel no choice but to take control.

Murphy also emphasizes the degree to which an initial lack of leadership in the city causes panic, crime, and disarray. Without adequate leaders, the city is unable to function properly. The actions of the committee and Free African Society are even more notable given the chaos all around them as major leaders flee.
