Choose some virtue not discussed by Aristotle (in Nicomachean Ethics) and present an Aristotelian analysis. Be sure to give a careful picture of what the virtue and its corresponding vices would look like.
When defining or identifying a virtue or vice not defined within Aristotle's Nicomachean Ethics, one must search hard. It seems,for some, that Aristotle was rather efficient in naming virtues and vices. That said, one virtue (which the defining of can tend to be rather subjective) he seems to have "forgotten" is accountability. While the recognition of virtues and vices is based upon one's ability to be accountable (or not accountable) for his or her actions, accountability fails to show up on Aristotle's list.
Using Aristotelian analysis (or logic), one remember that much of Aristotle's logic and reasoning revolved around deductions. (According to Aristotle, "a deduction is speech (logos) in which, certain things having been supposed, something different from those supposed results of necessity because of their being so" (Aristotle's Prior Analytics I.2).) Essentially, this ideology means that certain things are possible (let us say "Z") because of other things (let us say "Y"). Basically, "Y" brings about "Z," and (therefore) "Z" could not exist without "Y."
Under this logic, one possesses the virtue of accountability ("Z") based upon his or her recognition of that actions ("Y") brings about certain consequences (both positive and negative) under which a person accepts accountability.
The opposite of accountability, or the vice associated with accountability, is blameless or unaccountable. Under this, one would not recognize her or her responsibility associated with his or her actions.
