The quote reflects on the changing nature of mental health and societal perceptions of madness. The character suggests that Leland and his generation are disconnected from the traditional notion of going "mad." In the past, individuals could disappear from society when they became unhinged, almost romanticizing the experience. However, in modern times, self-awareness has changed the dynamic, making it more challenging for people to experience mental breakdowns in the classical sense.
Today, with increased accessibility to knowledge about psychological conditions, individuals are less likely to be completely taken by surprise by their own mental states. Leland and his peers are portrayed as overly aware of their emotions and symptoms, which diminishes the dramatic essence of losing touch with reality. This commentary highlights a significant cultural shift in how we approach mental health, suggesting that self-awareness may prevent the kind of "madness" that was once more common.
