Meaning: The quote you have provided touches upon the concept of international solidarity and the practice of worldwide division of labor, particularly emphasizing the role of free trade as a key component of internationalism. This idea is attributed to Christian Lange, a politician who was awarded the Nobel Peace Prize in 1921 for his efforts in promoting internationalism and disarmament.

The concept of international solidarity reflects the belief in a shared sense of responsibility and cooperation among nations, transcending geographical, cultural, and political boundaries. It signifies a commitment to upholding mutual support and assistance on a global scale, recognizing that the well-being of individuals and communities is interconnected across the world. This solidarity is expressed through various means, including economic collaboration, diplomatic relations, humanitarian aid, and the promotion of universal human rights.

One of the practical manifestations of international solidarity is the worldwide division of labor, which refers to the allocation of different stages of production and services across countries based on comparative advantages and specialization. This division of labor allows countries to focus on producing goods and services for which they have a competitive edge, thereby maximizing efficiency and productivity on a global scale. It also fosters interdependence and interconnectedness among nations, as they rely on each other's contributions to meet their diverse needs and demands.

At the core of this internationalist approach is the principle of free trade, which serves as a cornerstone of the program of internationalism, as mentioned in the quote. Free trade entails the exchange of goods and services between countries without the imposition of tariffs, quotas, or other barriers. It is based on the notion of comparative advantage, where each country specializes in producing the goods and services in which it is most efficient, and then engages in trade to obtain other goods and services that it cannot produce as effectively.

By facilitating the flow of goods and services across borders, free trade promotes economic growth, efficiency, and innovation, while providing consumers with a wider range of choices at competitive prices. Moreover, it fosters economic interdependence and cooperation among nations, as they engage in mutually beneficial trade relationships. Free trade also has the potential to reduce poverty, enhance global prosperity, and contribute to the overall well-being of societies by creating opportunities for economic development and job creation.

Christian Lange's emphasis on free trade as a principal point in the program of internationalism aligns with the broader perspective of promoting peace and cooperation among nations. His advocacy for free trade as a means of fostering international solidarity underscores the belief that economic interconnectedness can contribute to greater understanding, collaboration, and stability in the international arena.

In conclusion, the quote by Christian Lange encapsulates the idea of international solidarity and the practice of worldwide division of labor, with free trade serving as a key element in advancing the principles of internationalism. It underscores the interconnectedness of nations and the potential for economic cooperation to promote mutual prosperity and peace on a global scale. By embracing the concept of international solidarity and recognizing the significance of free trade, societies can work towards building a more interconnected and harmonious world.
