How did nationalism blur the line between philosophies?

Nationalism blurred the line between philosophies by intertwining cultural identity with political ideologies, leading to a merging of concepts such as patriotism, socialism, and liberalism. It often emphasized the importance of a unified national identity, which could overshadow individual rights and class struggles, creating a sense of collective purpose. This fusion allowed for the adaptation of various philosophical ideas to serve nationalist agendas, resulting in diverse interpretations and implementations across different contexts. Ultimately, nationalism transformed philosophical debates by prioritizing national unity over philosophical purity.
