Which of these transcendentalist ideas had the most direct impact on the civil rights movement of the 20th century?
god and nature are one and the same thing.
people should peacefully protest unjust laws.
self-reflection is the most direct way to find the truth.
individuals should make up their own minds about all matters.

The correct answer is B. People should peacefully protest unjust laws.

During the 20th-century, there were several civil rights movements influenced by Transcendentalist ideas taken from the writings of Henry David Thoreau and Ralph Waldo Emerson. These thinkers emphasized the notion of civil disobedience and peaceful protest in order to resist oppression and authoritarian and unjust governments. Examples of 20th-century movements that applied these ideas are the Indian independence movement led by Mahatma Gandhi, which ended in the liberation of India from British rule, and the American civil rights movements of the 60's led by Martin Luther King, which have fought against racism and oppression from the government towards African-American people.
