1962, about this song, Bob Dylan said, "I think the people who feel most guilty are those who see something wrong and know it is wrong, but just don't want to face it." Therefore, the questions raised by Bob Dylan in this song are tantamount to questioning justice and conscience again and again. History always does. A generation has to face the difficulties and doubts that a generation will encounter. The key to the solution is to achieve the least damage and achieve something. As an outstanding poet and singer in 1960s, Bob Dylan keenly grasped the young people's skepticism about war, violence and racial discrimination, and faced the problem directly. His songs based on his own observation and enthusiasm are unparalleled in internal strength and enlightenment. But the questions he keeps asking in this song are difficult to answer, and the answer is never simple. They are somewhere, "floating in the wind", elusive and close at hand, making people eager to try. In our society, what we hope is to find the answer as soon as possible, preferably at once, the sooner the better, the crux of the problem should be solved immediately, and the physical and mental pain should be eliminated immediately. Although these are difficult to achieve, can we give up such efforts? Poverty, injustice and war exist in every period of history, which is followed by many doubts. Bob Dylan and his contemporaries participated in thinking and acting together. Many of his songs, including this one, became hymns of the civil rights movement and the anti-war movement in the 1960s and 1970s. Through their dedication and sacrifice, they played a positive role in ending apartheid in the United States and played a major role in ending the Vietnam War.
