It is better to die for an idea that will live, than to live for an idea that will die. - Steve Biko

The most potent weapon of the oppressor is the mind of the oppressed.
So as a prelude whites must be made to realise that they are only human, not superior. Same with Blacks. They must be made to realise that they are also human, not inferior.

Black Consciousness is in essence the realization by the black man of the need to rally together with his brothers around the cause of their oppression.

At the time of his death, Biko had a wife and three children for which he left a letter that stated in one part: “I've devoted my life to see equality for blacks, and at the same time, I've denied the needs of my family. Please understand that I take these actions, not out of selfishness or arrogance, but to preserve a South Africa worth living in for blacks and whites.
