Spirituality 
In approximately 30 years as a college professor, I have taught biology (including evolution), the scientific method, and critical thinking to thousands of students. As students begin to understand the scientific worldview, they often have questions about how this relates to religion and spirituality in their lives. I heard stories such as the horrified reaction from family members when they returned home on breaks and told their grandmother they were studying evolution. It takes courage to question what you’ve long believed in the face of new knowledge. The willingness to be open to the possibility of changing your beliefs is a hallmark of scientific and critical thinking.
