In Howard Zinn's "A People's History of the United States," the author expresses a belief that the key to a hopeful future lies in the fleeting moments of kindness and empathy seen throughout history, rather than the enduring periods marked by conflict and violence. He suggests that looking back at these brief instances of compassion can inspire a more positive direction for society.

Zinn contrasts the transient nature of compassionate actions with the long-lasting impact of warfare, emphasizing that history is often dominated by the latter. By focusing on the moments of humanity and understanding that have occurred among people, he advocates for a shift in perspective that prioritizes peace and compassion over conflict, indicating that these values might guide future progress.
