Noam Chomsky debates Michel Foucault

"In the intellectual domain one is faced with the uncertainties that you pose. Our concept of human nature is limited, partial, socially conditioned, constrained by our own character defects, and the limitations of the intellectual culture in which we exist, yet at the same time it is of critical importance that we have some direction, that we know what impossible goals we’re trying to achieve if we hope to achieve some of the possible goals, we have to be bold enough to speculate and create social theories on the basis of partial knowledge while remaining open to the possiblity that in some respects we are way off the mark."
