For 240 years, the nation has looked to the American Academy of Arts and Sciences to offer wisdom and insight into the most profound issues of the time. In 1780, that was the formation of a free republic. In the 1850s, it was understanding the changing natural environment through the theory of evolution. In 1960, it was the creation and exploration of a field called arms control – in fact, the Academy coined that term. Today, it includes such questions as how we can sustain the dream of American democracy in the face of widening divides; and how as citizens of our planet we can respond to environmental change and its implications for migration, conflict, public health, and natural resources in order to provide for a more promising global future.
