Worth of an individual.

The angel and devil loved measurements for 'measurements are the blood of Science'.
"How do you measure the worth of an individual?"
"By the work he does. The way he works, his accomplishments."
"Work alone?"
"By the thoughts he disseminates. The way he analyses, his opinions."
"Only work and thought?"
"By the behavior he displays. The way he behaves, his rapport."
"Only work, thought and behavior?"
"By the appearance he carries. The way he looks, his hygiene."
"Only work, thought, behavior and appearance?"
"Ok, by many other factors too. Give me a break. What is your take on it? You don't agree with me?"
"No, I am afraid I asked the wrong question."
"Then what is your right question?"
"Who are we to measure the worth of an individual?"
