C.S. Lewis, in "The Screwtape Letters," underscores the importance of action in maintaining emotional depth. He suggests that if someone repeatedly experiences feelings but chooses not to act on them, they gradually lose the capacity for both action and emotion. This cycle diminishes their ability to engage with their feelings meaningfully over time.

This idea reflects a broader theme of the human experience: the necessity of responding to emotions rather than suppressing them. By acting on feelings, individuals assert their presence and influence in the world, enriching their emotional lives. In contrast, inaction leads to emotional numbness, ultimately impairing one's ability to connect with oneself and others.
