In this classic talk delivered at the Poetry Center, New York, on 16 February 1970, Noam Chomsky articulates a clear, uncompromising vision of social change. Chomsky contrasts the classical liberal, libertarian socialist, state socialist, and state capitalist world views and then defends a libertarian socialist vision as the proper and natural extension of classical liberalism into the era of advanced industrial society.' In his stirring conclusion Chomsky argues that the use of our material wealth and power is neither humane nor rational and he calls for radical change.'
