Abstract
Nostalgia is characterized by feelings of sentimentality and wistfulness. Once considered pathologic, nostalgia is now recognized as a normal and perhaps essential part of the human condition. Closely related to but distinct from nostalgia is a phenomenon known as "rosy retrospection." Rosy retrospection is a bias where individuals judge the past as being disproportionally superior to the present. Nostalgia plays a role in helping individuals and society gauge its progress and accomplishments. It also serves to offer comfort in difficult times. Individuals should be careful to understand the differences between nostalgia and rosy retrospection and make efforts to build nostalgic moments with colleagues and family members both inside and outside of the classroom.
