In times of change and uncertainty, human minds turn towards the age-old questions that have plagued them since the beginning of human thought. Who are we? Why are we here? And what are we here for? Gereon Kopf, Luther College professor of religion, will discuss how we develop identities and their psychological, political, moral and religious dimensions at 6 p.m. Tuesday, Feb. 9, in the Center for Faith and Life Recital Hall on the Luther campus.
