Quote by Ralph Waldo Emerson
Every revolution was first a thought in one man's mind and when the same thought occurs in another man, it is the key to that era.
Summary
This quote suggests that revolutions or significant changes in society begin with a thought or a new idea in one person's mind. However, it only becomes significant and influences the era when that same thought is shared and embraced by others. It emphasizes the role of collective thinking and unity in bringing about meaningful societal transformations throughout history.
