During the 1918 flu epidemic, it became apparent that scientific research required different characteristics of scientists. In a selected passage from The Great Influenza, John M. Barry uses exemplification, powerful diction, and figurative language to portray the work of a scientist as challenging and to depict scientists as those who should hold the qualities that are necessary in order to accomplish their goals. Barry’s use of powerful diction allows the audience to understand his overall purpose of communicating the challenges of experimentation and the qualities that grow from the experience. When describing the decisions that scientists must make, Barry describes the work as “tedious” and “grunt”. By utilizing a powerful diction, the reader realizes that a scientist goes through rigorous workloads. In order to describe the characteristics needed to overcome the anticipated uncertainty that is so common in science, Barry uses words such as “strength” and “courage”. When describing a scientist’s trek into the “unknown”, he uses words such as “wilderness” and “frontier” which further illustrates the uncertainties mentioned. In concluding these examples of the powerful diction he uses, readers can see that Barry is very successful in exuding the intensity of fieldwork. Barry uses exemplification to identify obstacles in science and to describe the certain actions to overcome them. When describing the creativity to overcome difficulties, Barry uses the example of examining a rock- “Would a pick be best, or would dynamite be better?” This theoretical question portrays Barry’s claim that creativity is a recurrent problem that scientists come up against in their work. He goes on to utilize a series of rhetorical question to simulate the train of thought in a scientist. For example, “If the rock is impenetrable, if dynamite would destroy what one is looking for, is there another way of getting information about what the rock holds? There is a stream passing over the rock. Would analyzing the water after it passes over the rock reveal anything useful? How would one analyze it?”. The train of thought that Barry gives an example of shows the complicated thoughts scientists have. These examples accommodate Barry in supporting the idea that complications rise in which scientist must use creativity and curiosity to figure them out. Barry is able to further illustrate a researcher’s challenges by comparing them to other situation and ideas by using several devices of figurative language like metaphor, simile, and allusion. When examining the “unknown boundary” that scientists must persist, Barry describes a “wilderness region” that is foreign to him. He continues to show that scientists endeavor “through the looking glass” into a new frontier, using an allusion from Alice In Wonderland. These devices help to create familiar ideas that will help the audience understand the situation. Another technique used was a simile that equated research to a “crystal” by elucidating that “probing’ was to “precipitate an order out of chaos.” Barry then applies a metaphor in order to discuss what follows a discovery. He portrays “a flood of colleagues” that “pave roads over the path laid.” This tells how science changes continuously, and that scientist benefits from the research already done from previous work. One discovery after another reveals the patience, curiosity, and creativity that a scientist must have. The figurative language Barry applies teaches a new way of apprehending for an audience that is unaccustomed to the author’s theme. Barry successfully relays the various trials that scientists will sustain in their work and the qualities that are fundamental in scientists by using three rhetorical devices-exemplification, powerful diction, and figurative language. His personal experience during the flu epidemic along with rhetoric combines to prove his allegation that there is more to science than what is superficial.
