The quote highlights the sea's unique role as a natural connector and separator between two significant European nations, France and England. The sea, in this context, becomes more than just a body of water; it symbolizes a bridge of possibilities, commerce, and cultural exchange, while also serving as a barrier that maintains distinct identities and sovereignty. This duality encapsulates how geographical features can profoundly influence relationships, politics, and perceptions. The sea has historically facilitated trade routes, enabling the exchange of goods, ideas, and people, which has substantially contributed to the development of both nations. At the same time, it acts as a formidable natural boundary that has, at times, fostered rivalry and conflict, emphasizing its complex role. The quote offers a poetic appreciation for the sea's significance—not just as a physical object but as a symbol of the nuanced relationship between neighboring countries. The notion that such a vast expanse of water can be considered a 'best thing' reflects an acknowledgment of its importance in shaping historical, economic, and cultural ties. It also implies a sense of beauty and admiration for the natural world, recognizing that despite differences and distances, the sea offers a form of unity and separation that many find profound. In a broader sense, the sea exemplifies how natural features can serve as metaphors for human relationships—highlighting the importance of boundaries, connection, and mutual respect. Overall, this quote encapsulates a romantic yet pragmatic view of one of nature's most enduring and influential elements.
