Meaning: This quote by John Buchan, a Scottish politician and writer, conveys the idea that the line between civilization and barbarism is much thinner and more fragile than we often perceive it to be. Buchan uses the metaphor of a wall, initially perceived as solid and impenetrable, to represent the perceived barrier between civilization and barbarism. However, he goes on to assert that this division is in fact more akin to a delicate thread or a sheet of glass, suggesting that it can be easily breached or broken with just a touch or a push. The mention of "the reign of Saturn" in the quote refers to a time of chaos and disorder in ancient Roman mythology, further emphasizing the fragility of the division between civilization and chaos.

The quote challenges the notion that civilization is inherently stable and secure, instead highlighting its vulnerability to external influences and internal disruptions. It serves as a reminder that the maintenance of civilization requires constant vigilance and effort, as well as an understanding of the potential for regression into chaos and barbarism.

In the context of history and politics, Buchan's quote can be interpreted as a commentary on the fragility of social order and the potential for a breakdown in civilized society. It suggests that the values and structures that underpin civilization are not as secure as they might seem, and that they require active protection and preservation. This idea has been echoed in various historical contexts, particularly during times of social and political upheaval when the stability of civilization has been called into question.

The quote also holds relevance in the contemporary world, particularly in discussions surrounding the potential for societal breakdown and the importance of upholding the principles of civilization. It serves as a cautionary reminder that the preservation of civilization is not a guaranteed outcome, but rather an ongoing process that requires attention and maintenance.

Buchan's background as a politician adds further depth to the quote, as it suggests an awareness of the intricacies of governance and the complexities of maintaining order within society. His experiences in politics likely informed his understanding of the delicate balance between civilization and chaos, and the potential for rapid shifts between the two states.

In conclusion, John Buchan's quote offers a thought-provoking perspective on the fragility of civilization and the potential for its disruption. By likening the division between civilization and barbarism to a fragile thread or a sheet of glass, he challenges the perception of civilization as an unassailable fortress, highlighting the need for ongoing vigilance and preservation. The quote serves as a reminder of the vulnerability of civilization and the imperative of safeguarding its principles in the face of potential regression into chaos and disorder.
