About
SAS Commons Overview
SAS Commons engages students, scholars, and the public with the goal of exploringa single theme across the arts and sciences over a two-year period. Through a variety of courses, programs, and events, the Commons fosters exchange across disciplines, the development of new ideas, and meaningful public dialogue.
Current Theme: Democracy and Knowledge
Can the arts and humanities, social sciences, and natural and physical sciences help us understand and even strengthen democratic practices and citizenship? Democracy and Knowledge explores the role that universities, and especially the forms of knowledge taught and produced across the liberal arts disciplines have to play in the present and future of democracy.
