Written in the 1970 a historical account of why people think Puerto Ricans are a lazy docile creature. A clear depiction of how imperialism and colonialism oppressed the boricua and how it can destroy IF YOU LET IT. Silén gloriously teaches the boricua how to stand up and resist and outlines the Achilles heel of the US. This is a must read for anyone who calls themself an activist for the liberation of Puerto Rico.
