Mandela's statement:
Mandela meant to say that both the oppressed and the oppressor are stripped of their humanity. In the context of apartheid in South Africa, where Mandela fought against racial segregation and discrimination, this statement highlights the dehumanizing effects of oppression on both sides.

Dehumanization of the oppressed:
1. Loss of dignity: The oppressed, who are subjected to discrimination, violence, and segregation, are stripped of their dignity. They are treated as inferior beings, denied basic human rights, and forced to live in impoverished conditions.
2. Suppression of freedom: The oppressed are denied the freedom to express themselves, voice their opinions, and participate in the decision-making process. They are restricted in their movements and opportunities, leading to a sense of helplessness and frustration.
3. Psychological impact: The constant discrimination and marginalization faced by the oppressed can have severe psychological consequences. They may experience feelings of powerlessness, anger, and resentment, leading to a loss of self-esteem and a distorted self-identity.
4. Limited opportunities: The oppressed are often denied access to quality education, healthcare, and employment opportunities. This perpetuates a cycle of poverty and hinders their ability to improve their circumstances and fulfill their potential.

Dehumanization of the oppressor:
1. Moral degradation: The oppressor, who enforces and benefits from the system of oppression, becomes morally corrupted. They are forced to suppress their empathy and compassion towards their fellow human beings, contributing to a loss of moral values.
2. Erosion of conscience: The oppressor becomes desensitized to the suffering they inflict on others. They may justify their actions through ideologies of superiority or maintain a willful ignorance of the consequences of their oppression.
3. Loss of authentic relationships: The oppressor's relationships become superficial, built on power dynamics rather than genuine connection. They are unable to engage in meaningful interactions with the oppressed, leading to a loss of empathy and understanding.
4. Limitations on personal growth: The oppressor's participation in oppression inhibits their own personal growth and development. By perpetuating a system of inequality, they hinder their ability to foster a just and inclusive society.

Conclusion:
Mandela's statement emphasizes that oppression not only harms the oppressed but also erodes the humanity of the oppressor. It highlights the need to address and dismantle systems of oppression to restore the inherent dignity and humanity of all individuals.
