In This Much I Know, a psychology professor’s quest to find his missing wife sets off a mind-bending journey through time and memory. Intertwining personal and historical narratives—including Stalin’s daughter fleeing to America, a young man confronting the white supremacist ideology he was raised with, and the haunting weight of unintended consequences—the play explores how we make choices, shift beliefs, and confront the limits of our control. Inspired by Daniel Kahneman’s Thinking, Fast and Slow, playwright Jonathan Spector delivers a bold, theatrical examination of the human mind and the complexity of moral responsibility.
