 There are two problems with this account. First, the understanding of the virtues may be thought too restrictive. As with loyalty, conscientiousness and sincerity can be directed to unworthy objects, but conscientiousness and sincerity do not for that reason fail as virtues. It is arguable that had Ewin given consideration to the view that virtues operate, as Philippa Foot puts it, “at a point at which there is some temptation to be resisted or deficiency of motivation to be made good” (Foot, 1978, 8)—he might have been able to accommodate them within a catalogue of virtues. Perseverance in human associations often requires individuals to make sacrifices for the good of the individual or group with whom the individual associates, sacrifices that self-interest naturally tempts us not to make.
