"I have never known anyone worth a damn who wasn't irascible"

This quote by Ezra Pound suggests that having a temper signifies worth. He implies that individuals who deserve something are typically irascible, or quickly outraged. This could be translated as a sign of enthusiasm and strength of character. People who deserve something are typically driven and identified, and this can manifest itself in a mood. It might likewise be translated as a sign of intelligence, as people who are smart typically have strong opinions and are not afraid to reveal them. In this way, Pound is recommending that having a temper suggests worth, which people who deserve something are frequently irascible.
