Graham Bradshaw, Shakespeare’s Scepticism (Ithaca, NY: Cornell University Press, 1987)
Summary from the Publisher:
Explores the question of value in Shakespeare’s drama. Bradshaw maintains that Shakespeare was preoccupied with the question throughout his career, and the plays themselves show how opposing visions of nature yield opposing accounts of value. He believes that Shakespeare’s skepticism in respect to value represents a mode of dramatic thinking, which depends on the practices and conventions of poetic drama and must be distinguished from the processes of logical discursive argument.
