This brief text addresses the question of the formation of Portuguese national identity. The title "Portugal: a unity of differences" suggests that the country is constituted by diverse differences that, nevertheless, were united over time.
The central argument of the text is that the Portuguese language played a fundamental role in the construction of national unity. According to the author, this linguistic construction occurred quite early in Portuguese history, long before it happened in other modern nations.
The text further suggests that language was the primary factor of cohesion that maintained the country's unity, implying that Portugal would never have existed as a coherent national entity without its common language. This idea positions language as a constitutive element of the Portuguese nation itself.
