To the extent that the humanities are not "rational", whatever that means, they are a valuable and useful complement, and the world need not be driven by rationalism alone.

The humanities teach how to look from multiple perspectives, our values, what we believe and why, our self and our relation to society. It teaches critical thinking and analysis of complex, nonquantifiable factors, such as: should we declare war on North Korea? What does it mean to be Chinese American? Should I trust this person, website, or TV station? The humanities are about life, and virtually all the themes are immediately applicable in daily life.
