The radical ideas of one generation have become the common sense of the next. We all stand on the shoulders of earlier generations of reformers, radicals, and idealists who challenged the status quo of their day. They helped change America by organizing movements, pushing for radical reforms, popularizing progressive ideas, and spurring others to action.

I'm always frustrated that most Americans, even activists, know so little about the movements and people that have made America a better country. Yes, we still have plenty of problems and progressives have much more work to do, but we also need to celebrate the progressive pioneers who fought and won many victories that have made America a more democratic, inclusive country.

Unless we know history, we will have little understanding of how far we have come, how we got here, and what still needs to change to make America and the rest of the world more livable, humane, and democratic.
