Boldly takes philosophy from the academy to the streets to show how great ideas are born through a profound engagement with the everyday. This companion to Astra Taylor's documentary film features interviews with eight iconoclastic and influential philosophers, conducted whilst on the move through places that hold special resonance for them and their ideas. Peter Singer's thoughts on consumption are amplified against the backdrop of Fifth Avenue; Michael Hardt ponders the nature of revolution; and Judith Butler ponders individualism.
