"Stirnerian self-mastery thus has both external and internal dimen­sions, demanding not only that we avoid subordinating ourselves to others, but also that we avoid submitting to our own appetites or ends. Stirner accepts the claim that if any idea or desire 'plants itself firmly in me, and becomes indissoluble', then I have 'become its prisoner and servant, a possessed man' (p. 127). This attack on the Christian 'fixedity' of ideas does not entail that the egoist can no longer allow herself to have ideas, but rather that she must never allow an idea to make her 'a tool of its realization' (p. 302). The egoist must exercise 'power' not only over 'the exactions and violences of the world', but also exercise this 'power over my nature' and avoid becoming the 'slave of my appetites' (p. 295). Stirner thus encourages the individual to cultivate and extend an ideal of emotional detach­ment towards both her passions and her ideas."
