The Stoics, as we have seen, held a developmental model of morality, thinking that we naturally come equipped with the ability to have regard not just for ourselves but also for our caretakers and other people with whom we come into regular contact early on in life. Once the age of reason arrives, however, when we are about seven or eight years old, we can begin to further build our virtuous character by two means: habit and (more so later in life) explicit philosophical reflection.
