The story “No Witchcraft for Sale” by “Doris Lessing” mainly shows cultural differences about health between white settlers and native Africans. The story shows how each culture ignores other person's culture until he learns something from the other culture. Gideon faced peer pressure, but he did not succumb because of this. He remained silent and did what he wished to do. Gideon did not reveal the secret of his secret medicine because whites were ignorant and were only interested in the black culture for the medicine that could save eyes (just as Teddy's eyes were saved).
When Gideon did not tell the truth, they thought he was lying and Teddy became well not because of his remedy.
Teddy also made racist comment about his son. Gideon was touched by the same. Still, he cared for Teddy. This story shows that we should remain true to ourselves, that is the most important, like Gideon.
If you could send over a picture of the passage that'll be great but the answer is that he is most famous for his "I have a Dream" speech. He wanted the US to be void of segregation and racism.
