“Command of the self is a goal of every person, because in absence of a personal identity and deprived of the ability to direct our actions we lack the means purposefully to interact with the external environment. Lacking self-control and deprived of the ability intentionally to engage with the world places us in a precarious position. Demonstrating self-doubt, personal ambivalence, and hesitation when action is called for endangers us, subjecting us to the capriciousness of the world filled with anarchy, chaos, and violence.”
