As per Aristotle, a good persuader needs to have the following 3 components in his speech
1. Ethos: Proving to the audience that he truly believes and follows what he/she says. Show them your authority.
2. Pathos: Appeal to the audience emotions. Charge them up.
3. Logos: Make a logical appeal. Give them some data, reason with them.
Only by using the 3 elements together, can one build a strong argument.
So which element do you normally use for arguing?
