Display theory predicts that no inferential relations among attitude attributions are based on the logical or semantic properties of the expressions in attribution complements. This chapter shows various ways in which there may be an illusion that such relations obtain. One common basis for the illusion is that we implicitly appeal to psychological facts. Since there is no reason to think these are necessary, the inferences are not truth preserving of necessity, even if they generally have true conclusions when they have true premises. They are examples of “plausible reasoning”. Wanting and fearing are discussed in detail as potential sources of the apparently inferential phenomena.

I have taught courses on political philosophy at four schools — the University of Chicago, Rosary College, Idaho State University, and Northern Illinois University. I have had to adjust the style of my teaching to conform to the distinctive character of each school. But I have found that the most fundamental obstacles to winning the attention of students have been the same.Many students have begun my courses with four unfavorable preconceptions. They believe that political philosophy is too abstract. And for that reason they also believe that it has no application to contemporary political issues. Moreover, many students assume that since the classic texts of political thought are old, the ideas they contain must therefore be obsolete. And finally they think that political philosophy is ultimately subjective because no philosopher can prove his ideas to be absolutely true.
