Ever heard the term, "use it or lose it"? What better way to underscore the essence of "ability."
One might say "ability" is talent, skill, a possession of means toward an accomplishment. Another might say "ability" is an art or a power, which perhaps might be a better understanding of the sense.
"Ability" stands as a virtue because it is a gateway to virtues. It is the intentional use of all faculties, everything that goes into making worthwhile attributes.
"Ability" is the art of improvement, accomplishment, the bed-rock of progress.
"Inability," in contrast, reveals the condition of disuse, an "uncondition" as it were. Inability is powerlessness, ignorance, ineptitude.
You are able to do good. Inability to do good is a choice.
