The virtue of temperance is best described as governing yourself through reason, being content with your state and being able to tame your impulses and appetites.
We find a rich cluster of synonyms for temperance. Moderation regulates your attraction to pleasure and balances your use of the good things in creation. Self-control is when you are the owner of yourself, taming your will to produce right action. Abstinence is knowing how to govern your passions and desires and being able to say “no” at the appropriate times. Meekness is being self-possessed in mitigating your anger, and is the middle ground between the opposing vices of irascibility and indifference in the presence of evil.
Does this describe you? If so, well done, you are a temperate person.
The vices that oppose temperance are licentiousness and self-indulgence, seen, for example, in the capital sins of gluttony, where there is no control in our relationship to food, or in lust, where there are no limits placed on sexual impulses. There are also excesses of temperance which can lead to self-denial and to unwarranted asceticism in which all pleasure is avoided.
Do any of these describe you? If they do, and if your score in the Virtue Test was low in this virtue, then you may want to choose to work on the virtue of temperance in your character.
