This quote from Evangeline Walton's Prince of Annwn highlights the immense power that questions hold, often surpassing the might of physical weapons. It compels us to consider that inquiry and curiosity can challenge established norms, provoke deep thought, and unleash transformative change. Unlike swords, which inflict immediate and visible damage, questions have a subtler, more enduring impact. They can erode outdated beliefs, spark revolutions, or reveal uncomfortable truths that some may prefer to keep hidden.

Moreover, questions are dangerous because they unsettle our sense of certainty and compel introspection. Asking 'Why?' or 'What if?' can disarm dogma and force societies or individuals to confront contradictions within themselves. In a way, questions disrupt complacency and demand progress, which can be threatening to those in power or to traditional systems.

This quote also reinforces the idea that knowledge and inquiry are forms of power. The danger of questions lies in their ability to provoke change, whether intellectual, social, political, or personal. In difficult times, the courage to ask the right questions is a catalyst for growth, even if it leads to discomfort or upheaval. Ultimately, questions can be a force for enlightenment and freedom, which are far more impactful than the transient damage of swords. The inherent 'danger' is a testament to their profound influence over minds and societies.
