Answer:
Because the Auld's had different views on how slaves should be treated.
Explanation:
Mrs. Auld believed that slaves were human beings who should be treated with dignity and respect and to help them achieve this type of treatment, she wanted to teach them to read and write, thus allowing them to have a minimum of academic education. . However, his mario, Mr. Auld, did not believe that slaves should be treated with any kindness or compassion. For him, treating slaves as beings worthy of any kindness demoralizes whites and takes away their authority over blacks.
Although Mrs. Auld believed that Frederick (and other blacks) should learn to read and write, Mr. Auld forbade her to teach them, lest they believe they were of any value.
