Final answer:
Chief Joseph most likely feels strongly about preserving and maintaining his tribe's cultural traditions.
Step-by-step explanation:
In the excerpt from 'An Indian's View of Indian Affairs,' Chief Joseph highly values what his father has taught him. From this, we can infer that he most likely feels strongly about preserving and maintaining his tribe's cultural traditions. This is supported by the fact that many Native people today are actively seeking to reassociate themselves with their tribal cultures, recognizing this part of their heritage as a central part of their identity.
