Values can be good or bad. Some people value peace, others war. Virtues, on the other hand, are absolute. Kindness is always good. Patience is always good.
Justice is always good.
Therefore, virtue is primary in importance, value is secondary. By confusing these categories, we frequently put values ahead of virtues. For example, present American culture places freedom ahead of responsibility. This is a disastrous view. Freedom is a value, something I very much want.
