Final answer:
Zola's perspective on medicine's role includes both the evolution of practices from simple herbal remedies to advanced pharmaceuticals and medical instruments, as well as the ethical dimensions introduced by modern medical technologies.
Step-by-step explanation:
According to Zola (1972), medicine's role was multifaceted, contributing not only to the treatment of diseases but also to the broader understanding of cultural and societal influences on health. Medical practices and knowledge advanced significantly over time, evolving from rudimentary and often ineffective treatments to more sophisticated, evidence-based interventions.
The use of medicinal plants and the development of pharmaceuticals and medical instruments, such as the ophthalmoscope and the x-ray, greatly enhanced diagnostic capabilities and treatment efficacy. The work of pioneers like Robert Koch and Louis Pasteur led to the germ theory of disease and the creation of vaccines that have saved countless lives. Moreover, the role of medicine extends into ethical realms, raising questions about end-of-life decisions and the application of medical technology.
