In "The Ruby in the Smoke," Philip Pullman delves into the complexities of emotions and mental states. The quote "She's mad. Best leave her be, in case it's catching" reflects a societal attitude towards madness, highlighting how fear can lead to isolation. It suggests that those who exhibit signs of distress are often misunderstood and avoided, revealing a deep-seated stigma surrounding mental health.
The phrase implies that madness is seen not only as an individual burden but also as something that can spread, creating an aversion among others. This perspective underscores the importance of compassion and understanding, urging society to reconsider its response to those struggling with their mental health rather than shunning them.
