  However, Yablo (2001) emphasizes that the figuralist need not be committed to any psychological thesis about making-believe. We may not consciously pretend that there are propositions when we say that what we believe is true, just as we may not consciously pretend that there are such things as stomach butterflies when we say we have butterflies in our stomach. Figuralism requires only that there is a semantical distinction between literal content and figurative content, and that by asserting sentences with certain false or at least highly doubtful literal contents, we may also express genuine facts, which would be well nigh impossible to express literally.
