Final answer:
Cicero's 'De Inventione' shares similarities with Aristotle's works in the emphasis on rhetorical techniques such as the modes of persuasion, the role of reason in understanding the universe, and the investigation of complex concepts through observation and categorization.
Step-by-step explanation:
The similarities between Cicero's 'De Inventione' and the works of Aristotle can be observed in their foundational influence on the fields of rhetoric and philosophy. Cicero's 'De Inventione' is a treatise on rhetoric that bears resemblance to Aristotle's works in several aspects.
For instance, Aristotle's articulation of the modes of persuasion—ethos, pathos, and logos—are essential to the art of rhetoric, which Cicero elaborates upon in his rhetorical framework. Moreover, both Aristotle and Cicero emphasize the importance of the invention (invention) aspect of rhetoric, which involves finding arguments.
Cicero's work is highly reminiscent of Aristotelian thought, embracing the idea that effective communication is grounded in an understanding of logic and ethical argumentation, elements that Aristotle explored in-depth within his discussions of metaphysics and ethics.
Additionally, both thinkers shared the belief that the universe was comprehensible, and that reason should guide life, a principle that underpins much of their philosophical and rhetorical work.
They also investigated concepts not easily reducible to simple forms, like 'the good', and stressed natural observation and categorization which is essential in Aristotle's biological classifications and in Cicero's rhetorical strategies. In summary, 'De Inventione' echoes the Aristotelian view that effective argumentation, ethics, and the structure of nature are interrelated and comprehensible through rational inquiry.
