Persuasion is achieved by the speaker's personal character when the speech is so spoken as to make us think him credible. We believe good men more fully and more readily than others: this is true generally whatever the question is, and absolutely true where exact certainty is impossible and opinions are divided.
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.
