Step-by-step explanation:
The philosopher who argued that words have three types of rhetoric or persuasion was Aristotle.
Aristotle defined rhetoric as the ability to find the appropriate means of persuasion in any given situation, offering a systematic treatment of the subject in his work titled Rhetoric.
