In her work, Dorsey draws from personal experience, contemporary Ikebana, and design principles.

Type “God” into Google and you’ll get nearly 2 billion search results. God even has His (or Her) own (unverified) Twitter feed. But despite the sophisticated arguments postulated by believers and non-believers, God’s existence remains in dispute. For Penn’s 2012-13 “Year of Proof,” the Rare Book & Manuscript Library presents “Resolved? God Does Not Exist,” a small exhibition selected from the Library’s primary source collections that shows examples of individual works that attempt to prove or disprove the existence of God. The exhibit, which runs through Feb. 24, 2013, is on display on the first floor of the Van Pelt-Dietrich Library Center, 3420 Walnut St, next to the Information Desk. For more information, call 215-898-7088 or email rbml@pobox.upenn.edu.
