Philanthropy and voluntarism have played a unique role in the development of American society, but Americans have always been uneasy about the influence of great private wealth on public policy. Eric John Abrahamson, co-author of the new book Democracy and Philanthropy, is principal historian and founder of Vantage Point Historical Services. He'll talk about this tension in American history and lead a general discussion of the role of philanthropy in South Dakota and the United States today this Sunday at 2:00 p.m. in the Wells Fargo Theater at The Journey Museum.
