TL;DR Recommendation: Change definition of Stoic to:
A character who believes the greatest good is peace of mind obtained via mastery over one's desires and emotions, who can be disconcerted by nothing that lies outside the sphere of choice.
First, a Stoic is one who practices Stoicism, which is a philosophy which happens to be bound up with some ethical practices as well. So either all Ethics categories should refer to the person, i.e., Stoic, or an "-ist", or it should refer to the category of the trait, or an "-ism", IMO. Current definition on Litphoria:
A character who believes that the individual's will should be independent of concepts of good and bad, and inviolate.
A better rewording of what they wrote for Stoic is:
One who believes that the individual's will should be inviolate, and independent of concepts of good and bad.
This is an incorrect definition.
"Where is the good? In the will. Where is the evil? In the will. Where is neither of them? In those things that are independent of the will." --Epictetus
The Stoics believed Virtues were good, and that remaining virtuous, including chastity, was key to achieving peace of mind. Stoics, held that the good lies not in external events or objects but in the virtuous response of the moral agent to any situation.
What, more clearly, a Stoic really is:
One who believes the greatest good is peace of mind obtained via mastery over one's desires and emotions, who can be disconcerted by nothing that lies outside the sphere of choice.
Very Vulcan, I think.
