In Orson Scott Card's book "Empire," the idea of personal affection is explored through the lens of conflict and danger. The quote suggests that one can only truly afford to love others when they are no longer threatened by foes. Until then, caring for someone can become a liability, as those we love may be used against us, draining our strength and clouding our decision-making abilities.

This perspective highlights the tension between emotional connections and the harsh realities of survival. Relationships can be seen as vulnerabilities in a tumultuous environment, where the presence of enemies complicates the instinct to care for others. Ultimately, the notion implies that love must sometimes be delayed until safety is assured, emphasizing the struggle between personal desires and the need for security.
