Aristotle is
considered to be the “father” of modern speaking. He was a Greek philosopher
who lived in the 4th century BC and put forward three rules for
public speaking. They are ethos (human character), pathos (emotional appeal)
and logos (logical reason). All three should be included in any speech,
although Aristotle preferred to follow logical reasoning, saying that:
“An emotional
speaker always makes his audience feel with him, even when there is nothing in
his arguments; which is why many speakers try to overwhelm their audience by mere
noise.” (as cited on https://mannerofspeaking.org
