While speaking of national liberation, Cabral uses culture to explore how ideas such as freedom, oppression and dominance can be sought and manipulated. He examines the power structures in place in colonial rule, both between the colonizers and colonized and within the natives and what part culture can play to either enforce or dismantle these relationships.
Cabral describes culture as something fluid that can be altered or controlled. According to him, the success of colonial powers depends on their ability to either crush the culture of their native subjects, or manipulate it to their use. He views the local culture as an extremely important force, as it is the driving factor behind the movements that seek to oppose and overthrow the foreign rulers. The culture is what unites and motivated the people, providing them the strength and inclination to stand up against colonial rule, which is why it must be disassembled as much as possible to ensure a successful reign. It can be manipulated to control the local population as well, such as the example given by Cabral of how Europeans ruled through chiefs and royals, using their already existing influence in their societies. Thus, Cabral defines the local cultures as weapons of both the oppressors and the oppressed.
Cabral also emphasizes on the importance of culture in terms of how it contributes to the society. He defines a dual relationship between the history and culture of the area, that is the past of the people of a particular region is what shapes the culture. The culture provides a lens through which we can view the past conflicts of our society, the struggles that have taken place and how they have been overcome. It shows the evolution of the society. To know and understand the culture of another region makes it easier to control, which is why Cabral states that there is a greater chance of success in ruling over people with a similar culture. Cabral speaks of it as one of the most important tools in the struggle between dominance and freedom.
