Septimus Warren Smith is a quintessential INFP, with dominant Introverted Feeling (Fi) and auxiliary Extraverted Intuition (Ne). His entire existence is governed by a deep, internal value system (Fi) focused on authenticity, humanity, and profound emotional connection. His trauma stems from his failure to feel—his numbness at his friend Evans’s death—which violates his core Fi principles, leading to overwhelming guilt and a fractured sense of self. His Fi is not oriented toward societal norms but toward a private, intense morality, making him feel utterly alienated from the post-war world that values stoicism and convention. His auxiliary Ne manifests in his hallucinatory, symbolic perception of the world. He does not simply see trees or clouds; he sees intricate patterns, messages, and profound truths within them (‘Fear no more,’ the rustling leaves whisper). This Ne, untethered from healthy coping mechanisms, runs in a negative loop with his Fi, generating terrifying and ecstatic visions that are his attempts to process his internal agony and find meaning. His inferior Extraverted Thinking (Te) is critically weak. He is incapable of organizing his external world, relying on his wife Rezia to manage practicalities. The authoritative, logical Te of doctors Holmes and Bradshaw represents his inferior function in its destructive, persecutory form; their insistence on ‘proportion’ and institutionalization is the antithesis of his inner world and ultimately destroys him. His tertiary Introverted Sensing (Si) is negatively engaged, trapping him in vivid, intrusive flashbacks of the war and his failure, reinforcing his despair rather than providing comfort from the past.
