 Moss contributed to experimental literary theory by introducing the metaphor of a fork to conceptualize how people internalize art and literature.The fork as a metaphor for understanding represents bifurcation, and Moss argues that the branching out of the mind to understand art mimics the branching tines of a fork.She uses the word "limited" to express that, though an observer gains understanding of art through these bifurcated systems of comprehension, the same systems limit their understanding.
