The 3 dimensions of argument

In this essay, I’m going to remind you of 3 ancient strategies for persuasion. 

When passionately arguing, it’s easy to feel that only a binary is possible - “yes, you’ve convinced me” or “no, I’m not persuaded”. The fundamentals of persuasion - logos, pathos and ethos - give you options. 

Despite making arguments everyday, most people don’t do it in 3 dimensions.

Making an argument is like driving a car 

You can drive without understanding how a car works. Driving becomes autonomic behaviour - spontaneous and involunatary. But unthinking behaviour leads to bad habits when driving or persuading.

  • Failing to personalise or bring to life

  • Not providing supporting facts or statistics

  • Unconsciously using logical fallacies

  • Not providing any credentials or sources

  • Failing to consider (and refute) opposing arguments

So meet your 3 new best friends and musketeers - pathos, logos and ethos.

Pathos: appeal to emotion

Evoke emotion to make your audience feel the way you want them to and “frame” their response.

“Imagine you are in a heated argument feeling more and more frustrated …”

Logos: appeal to logic

Ensure your argument is reasonable, connects to facts and analogies and avoids assumptions or weak connections.

“Bad arguments are like bad driving habits - they cause 60% of accidents”

Ethos: appeal to credibility

Finally, why should the audience trust you, no matter how good the argument? 

“As a consultant with 20 years experience I’ve persuaded a lot of people. Plus, who’s going to argue with the ancient Greeks?”
