Wiener is “the most attractive figure at MIT” for John Nash, a polymath known as the “father of cybernetics” (“the scientific study of control and communication in the animal and the machine”). Wiener, like Nash, is famously eccentric and suffers from a mental illness; as a result, he has “an acute empathy for other people’s trials,” including Nash’s, and serves as a mentor to Nash, who views him as a “kindred spirit.”
