The question must be rhetorical; it implies that there are in fact no grounds for fear. The audience’s foreknowledge that Iokaste’s argument must prove baseless will prompt it to overturn her reasoning point by point lest it find itself in a position as unsupportable as hers. To accept Iokaste’s false reasoning jeopardizes the audience’s reliance on its own capacity for reason. It is reasonable to fear prophecy. It is unreasonable to deny this fear. [Mpea] [Mi]
