The duty of rhetoric is to deal with such matters as we deliberate upon without arts or systems to guide us, in the hearing of persons who cannot take in at a glance a complicated argument or follow a long chain of reasoning.
Aristotle was an ancient Greek philosopher and polymath who made significant contributions to various fields, including philosophy, science, logic, and ethics. He was a student of Plato and a tutor to Alexander the Great. Aristotle's works, such as "Nicomachean Ethics" and "Metaphysics," explored fundamental questions about human nature, morality, and the nature of reality. His systematic approach to knowledge and his influential ideas have had a profound impact on Western philosophy and continue to be studied and debated today.
