'Days of Endless Time' at the Hirshhorn examines our need for nature to soothe us

If you believe you have a soul, then likely you believe that Nature is a balm for all that ails it. But both are fictional constructs, drawing on ideas borrowed from religion, philosophy, poetry and the arts. Many of the works on view in the Hirshhorn Museum's exhibition "Days of Endless Time" reflect the sadness and anxiety we feel when we face up to these facts dispassionately and honestly.
