For the fan of hard evidence
Education in the humanities also provides us with unique and powerful opportunities to hone our skills of critical analysis and develop clarity of thought and expression. In every pursuit and profession, the expression of ideas is inextricably linked to the formulation of ideas. It is through written and spoken communication that we shape and refine our thoughts.
Translation: humanities force us to practice critical thinking and analysis, and practice makes perfect.

Examining differences in values and reasoning enables us to reflect thoughtfully on the normative framework we have as individuals and as members of a society. The humanities challenge us to question our assumptions, examine our beliefs and develop new ways of thinking about “conventional” wisdom. This appreciation for other modes of thought enables us to see complexity and uncertainty as key elements in the process toward discovering new truths. When viewed in this context, the journey we travel becomes as important as the destinations we reach.
Translation: humanities makes us better people.
