In her third provocative CBC Massey lecture, Canadian-American filmmaker, writer, political organiser, rock musician  and self-described "feral intellectual" Astra Taylor argues our innate existential insecurity is vital to our curiosity,  creativity, compassion, and capacity to care. Drawing on her own childhood, she asks, how can educators better foster these? We're in the middle of an attack on our essential nature, Astra argues, with confronting consequences for our society and state of mind. In this 5 part CBC Massey lecture series, Astra explores how our society now runs on a sense of manufactured insecurity — and what needs to change.
