If you argue to be dominate, to be right over another, you’re missing the point. The aim of discussing alternative points of view together is to arrive at the best answer, or a better answer for both. To do the right thing, not to be right.
If there is no exchange of knowledge, the argument is largely pointless. If emotions flare, a shared sense of objectivity has been lost. If neither learns to consider and accept an appreciation of each others point of view, the time was wasted.
Aim to progress a dialogue and the actions you will eventually come to take. Don’t engage to win by putting another in their place below you, engage to learn from one another. Know the point of argument so that you will gain something from it over time.
“It is better to debate a question without settling it than to settle a question with debating it.” — Joseph Joubert —
