"Proof . . . a play about scientists whose science matter less than their humanity . . . All four [characters]—whether loving, hating, encouraging or impeding one another--are intensely alive, complex, funny human." —John Simon, New York
"An exhilarating and assured new play . . . accessible and compelling as a detective story." —Bruce Weber, The New York Times
"Auburn has taken on some biggies here; what the link may be between genius and mental instability, why it is that lives get stuck, and how elusive the truth can be . . . [Proof's] level of accomplishment and the realness of its characters show that Auburn has both depth and a voice." —The New Yorker
