- IDEA 1 OF 8
Persuasion is an ancient art
Heinrichs argues that rhetoric, the art of persuasion taught by ancient thinkers such as Aristotle and Cicero, is useful in everyday life.
He uses examples from family arguments to politics.
- IDEA 2 OF 8
Arguing differs from fighting
Heinrichs distinguishes arguing, which aims to persuade, from fighting, which aims to win or hurt.
Good argument seeks agreement. In his account, a good arguer treats the other side as a person to persuade, not an enemy.
- IDEA 3 OF 8
Character persuades
Heinrichs explains ethos, persuasion based on the speaker's character and credibility.
People listen to those they trust. In his view, a speaker who shows good sense, goodwill and good values is heard more fairly than one who does not.
- IDEA 4 OF 8
Emotion persuades
Heinrichs explains pathos, persuasion through emotion.
Feelings often move people more than facts. In his view, a speaker who connects with how the listeners feel is more likely to be heard. Facts alone can pass by without notice.
- IDEA 5 OF 8
Logic persuades
Heinrichs explains logos, persuasion through reasoning and evidence.
A clear argument strengthens a case. In his view, strong evidence and a clear chain of steps help the audience see why a conclusion follows.
- IDEA 6 OF 8
Focus on the future
Heinrichs explains Aristotle's three tenses of argument: blame about the past, values about the present and choices about the future.
Choices, he argues, are best for agreement. He sees this as the way to move from quarrels to action.
- IDEA 7 OF 8
Fit the audience
Heinrichs explains decorum, adapting speech to suit the audience.
What works depends on who is listening. A joke that works with friends may fall flat in a meeting, and a formal speech may seem cold at a party.
- IDEA 8 OF 8
Spot the tricks
Heinrichs describes logical fallacies and tricks so readers can recognise them in others' arguments.
