 A larger revision will be demanded by many Aristotelians, namely that the list of virtues include practical wisdom (Kristjánsson 2013: chapter 7). On traditional Aristotelian approaches, practical wisdom is necessary for the possession of any virtue. Leaving it off the list would be a serious omission, but again there is nothing about Peterson and Seligman’s framework that would preclude it from being added (for more on practical wisdom, see Russell 2009; Miller forthcoming).
