‘The problem’ asks: What are nations? What is nationalism? How do the two differ? Throughout history humans have grouped together into societies based on their ancestry and location, which engenders an ‘us’ versus ‘them’ mentality. However, they also coalesce on a global scale into organizations such as empires or religious groups, and cooperate through trade and scientific research. A nation is simply a particular kind of society. Nationalism, on the other hand, is the possession of beliefs about a nation, particularly the belief that the ‘nation’ is the only goal worthy of pursuit. This mindset can cause problems for societies on a local and global scale.
