The ambition to think on the scale of thousands, millions, even billion of years emerged in the 19th century. Historian and author Caroline Winterer chronicles how the concept of “deep time” has inspired and puzzled thinkers in cognitive science, art, geology (and elsewhere) to become one of the most 
influential ideas of the modern era. Caroline Winterer is Anthony P. Meier Family Professor in the Humanities and Director of the Stanford Humanities Center.
