Arts and Sciences is a world of learning, a world where the pursuit for knowledge never ends, where endless opportunities begin. Arts and Sciences is a world where chemists and philosophers, linguists and mathematicians, social scientists and natural scientists, geologists and geographers, astronomers, anthropologists, statisticians and historians are united by a common purpose: to understand the forces that shape our lives and our universe, and to share their knowledge with current and future generations. Unlike other branches of the modern university, only Arts and Sciences is charged with exploring the full domain of knowledge.
What an Arts and Sciences education teaches is the ability to think critically -- to learn, to adapt to ever-changing environments, and to make informed judgements. Equipped with this fundamental life skill, Arts and Sciences graduates are well prepared not only for the next ripple of technological and cultural evolution, but for the endless waves of change that mark human progress.
