In traditional rhetorics, the uncertainty of any argument reflects the limits of the rhetor's knowledge base (the weight of the evidence) and the confidence with which a rhetor can argue a proposition.4 In a postmodern rhetoric where neither signifier nor signified can lay claim to fixed and certain meaning, it becomes easy to argue that any attempt to talk about the material world will be fraught with linguistic and discursive uncertainty. In a society without foundational truths, uncertainties also arise when individual subjects conceive different and thus potentially conflicting views of the same situation.
