Final answer:
The statement is true: like aspiring athletes learn from experts, those wishing to be virtuous should model their behavior on virtuous people. Virtues are developed through practice and habit, emulating good models and learning from observation and action.
Step-by-step explanation:
True: The statement that continent and incontinent people who wish to be virtuous should model their behavior on that of virtuous people is indeed true. This concept is echoed in various philosophical teachings which suggest that by mimicking those who exhibit virtuous behavior, we can cultivate such virtues within ourselves.
In the realm of virtue ethics, it is recognized that we develop virtues not simply by learning about them, but through practice and habituation. This is analogous to a quarterback learning the game by watching skilled players, or a builder becoming skilled only by the act of building.
According to Aristotle's philosophy, virtues are developed through repeated actions. Just as a builder becomes good by building well, a person becomes virtuous by performing virtuous acts.
Similarly, as stated by Epictetus, we learn and develop through imitation and practice. However, discernment is required, as highlighted by the example of Julian learning both what to do and what not to do by observing his father.
It is important, as well, to have good models for behavior, as underscored by the proverbs which suggest reflecting on others' qualities to either emulate them or to turn inward for self-improvement.
