Final answer:
Professor M. Walden likely values the contributions of earlier scientists and understands their role in advancing knowledge. He likely supports the idea of scientists engaging in public education, similar to Carl Sagan, and sees it as part of a scientist's responsibility. Walden probably views his work as a continuation of the efforts of his intellectual predecessors.
Step-by-step explanation:
To understand Professor M. Walden's opinion of scientists that came before him, it is essential to consider the context in which scientists perceive and build upon the body of work left by their predecessors. Walden likely acknowledges that early figures like Marsh and Wallace are common intellectual ancestors who set the foundation for current fields, such as conservation biology, with their 19th-century perspectives on biodiversity and ecology. Walden would likely align with the idea that past scientists were instrumental in shaping not just the scientific domain but the public's perception of science. The reference to Carl Sagan suggests that Walden might appreciate those who popularize science and make it accessible, embodying the belief that scientists should communicate their research to the public. The mention of Alfred Russel Wallace denotes the earlier call for scientists to assume responsibility for knowledge dissemination and proactive stewardship—an attitude that seems to resonate with Walden's perceived view.
The discussion about understanding Shakespeare's art by using critics of the seventeenth and eighteenth centuries as an example shows an appreciation for historical context and a realization that interacting with past works enriches our present understanding of any subject. Walden would potentially see himself as part of the continuum in this effort, both contributing to and relying on the wider scientific dialogue. In summary, Professor M. Walden might value the contributions of earlier scientists, recognizing their integral role in advancing knowledge and shaping the conversation in their respective fields. Furthermore, the advancement of public understanding, demonstrated through figures such as Sagan, is likely seen by Walden as a crucial aspect of a scientist's work, thereby honoring his predecessors while continuing their legacy of inquiry and education.
