 The Stoics also discuss a notion of freedom that is rather more moral than metaphysical. This sense of freedom involves ‘the power to live as you will’ (Cicero, Stoic Paradoxes 5, 34). It turns out, for reasons that will be discussed below in the section on ethics, that only the Stoic wise man is truly free. All others are slaves. This notion of freedom and its relation to Kantian autonomy is discussed in Cooper (2004).
