JFK - 100 - May 29, 1917

"In a world of complex and continuing problems, in a world full of frustrations and irritations, America's leadership must be guided by the lights of learning and reason - or else those who confuse rhetoric with reality and the plausible with the possible will gain the popular ascendancy with their seemingly swift and simple solutions to every world problem."  
JFK. Remarks prepared for delivery at the Trade Mart in Dallas. November 22, 1963.
